+Digest::MD5 - Perl interface to the MD5 Algorithm

+=head1 SYNOPSIS

+ # Functional style
+ use Digest::MD5 qw(md5 md5_hex md5_base64);
+
+ $digest = md5($data);
+ $digest = md5_hex($data);

+
+=head1 DESCRIPTION
+
+The C<Digest::MD5> module allows you to use the RSA Data Security
+Inc. MD5 Message Digest algorithm from within Perl programs. The
+algorithm takes as input a message of arbitrary length and produces as
+output a 128-bit "fingerprint" or "message digest" of the input.
+
+Note that the MD5 algorithm is not as strong as it used to be. It has
+since 2005 been easy to generate different messages that produce the
+same MD5 digest. It still seems hard to generate messages that
+produce a given digest, but it is probably wise to move to stronger
+algorithms for applications that depend on the digest to uniquely identify
+a message.
+
+The C<Digest::MD5> module provide a procedural interface for simple
+use, as well as an object oriented interface that can handle messages
+of arbitrary length and which can read files directly.
+
+=head1 FUNCTIONS
+
+The following functions are provided by the C<Digest::MD5> module.
+None of these functions are exported by default.
+
+=over 4
+
+=item md5($data,...)
+
+This function will concatenate all arguments, calculate the MD5 digest
+of this "message", and return it in binary form. The returned string
+will be 16 bytes long.
+
+The result of md5("a", "b", "c") will be exactly the same as the
+result of md5("abc").
+
+=item md5_hex($data,...)
+
+Same as md5(), but will return the digest in hexadecimal form. The
+length of the returned string will be 32 and it will only contain
+characters from this set: '0'..'9' and 'a'..'f'.
+
+=item md5_base64($data,...)
+
+Same as md5(), but will return the digest as a base64 encoded string.
+The length of the returned string will be 22 and it will only contain
+characters from this set: 'A'..'Z', 'a'..'z', '0'..'9', '+' and
+'/'.
+
+Note that the base64 encoded string returned is not padded to be a
+multiple of 4 bytes long. If you want interoperability with other
+base64 encoded md5 digests you might want to append the redundant
+string "==" to the result.
+
+=back
+
+=head1 METHODS
+
+The object oriented interface to C<Digest::MD5> is described in this
+section. After a C<Digest::MD5> object has been created, you will add
+data to it and finally ask for the digest in a suitable format. A
+single object can be used to calculate multiple digests.
+
+The following methods are provided:
+
+=over 4
+
+=item $md5 = Digest::MD5->new
+
+The constructor returns a new C<Digest::MD5> object which encapsulate
+the state of the MD5 message-digest algorithm.
+
+If called as an instance method (i.e. $md5->new) it will just reset the
+state the object to the state of a newly created object. No new
+object is created in this case.
+
+=item $md5->reset
+
+This is just an alias for $md5->new.
+
+=item $md5->clone
+
+This a copy of the $md5 object. It is useful when you do not want to
+destroy the digests state, but need an intermediate value of the
+digest, e.g. when calculating digests iteratively on a continuous data
+stream. Example:
+
+ my $md5 = Digest::MD5->new;
+ while (<>) {
+ $md5->add($_);
+ print "Line $.: ", $md5->clone->hexdigest, "\n";
+ }
+
+=item $md5->add($data,...)
+
+The $data provided as argument are appended to the message we
+calculate the digest for. The return value is the $md5 object itself.
+
+All these lines will have the same effect on the state of the $md5
+object:
+
+ $md5->add("a"); $md5->add("b"); $md5->add("c");
+ $md5->add("a")->add("b")->add("c");
+ $md5->add("a", "b", "c");
+ $md5->add("abc");
+
+=item $md5->addfile($io_handle)
+
+The $io_handle will be read until EOF and its content appended to the
+message we calculate the digest for. The return value is the $md5
+object itself.
+
+The addfile() method will croak() if it fails reading data for some
+reason. If it croaks it is unpredictable what the state of the $md5
+object will be in. The addfile() method might have been able to read
+the file partially before it failed. It is probably wise to discard
+or reset the $md5 object if this occurs.
+
+In most cases you want to make sure that the $io_handle is in
+C<binmode> before you pass it as argument to the addfile() method.
+
+=item $md5->add_bits($data, $nbits)
+
+=item $md5->add_bits($bitstring)
+
+Since the MD5 algorithm is byte oriented you might only add bits as
+multiples of 8, so you probably want to just use add() instead. The
+add_bits() method is provided for compatibility with other digest
+implementations. See L<Digest> for description of the arguments
+that add_bits() take.
+
+=item $md5->digest
+
+Return the binary digest for the message. The returned string will be
+16 bytes long.
+
+Note that the C<digest> operation is effectively a destructive,
+read-once operation. Once it has been performed, the C<Digest::MD5>
+object is automatically C<reset> and can be used to calculate another
+digest value. Call $md5->clone->digest if you want to calculate the
+digest without resetting the digest state.
+
+=item $md5->hexdigest
+
+Same as $md5->digest, but will return the digest in hexadecimal
+form. The length of the returned string will be 32 and it will only
+contain characters from this set: '0'..'9' and 'a'..'f'.
+
+=item $md5->b64digest
+
+Same as $md5->digest, but will return the digest as a base64 encoded
+string. The length of the returned string will be 22 and it will only
+contain characters from this set: 'A'..'Z', 'a'..'z', '0'..'9', '+'
+and '/'.
+
+
+The base64 encoded string returned is not padded to be a multiple of 4
+bytes long. If you want interoperability with other base64 encoded
+md5 digests you might want to append the string "==" to the result.
+
+=back
+
+
+=head1 EXAMPLES
+
+The simplest way to use this library is to import the md5_hex()
+function (or one of its cousins):
+
+ use Digest::MD5 qw(md5_hex);
+ print "Digest is ", md5_hex("foobarbaz"), "\n";
+
+The above example would print out the message:
+
+ Digest is 6df23dc03f9b54cc38a0fc1483df6e21
+
+The same checksum can also be calculated in OO style:
+
+ use Digest::MD5;
+
+ $md5 = Digest::MD5->new;
+ $md5->add('foo', 'bar');
+ $md5->add('baz');
+ $digest = $md5->hexdigest;
+
+ print "Digest is $digest\n";
+
+With OO style you can break the message arbitrary. This means that we
+are no longer limited to have space for the whole message in memory, i.e.
+we can handle messages of any size.
+
+This is useful when calculating checksum for files:
+
+ use Digest::MD5;
+
+ my $file = shift || "/etc/passwd";
+ open(FILE, $file) or die "Can't open '$file': $!";
+ binmode(FILE);
+
+ $md5 = Digest::MD5->new;
+ while (<FILE>) {
+ $md5->add($_);
+ }
+ close(FILE);
+ print $md5->b64digest, " $file\n";
+
+Or we can use the addfile method for more efficient reading of
+the file:
+
+ use Digest::MD5;
+
+ my $file = shift || "/etc/passwd";
+ open(FILE, $file) or die "Can't open '$file': $!";
+ binmode(FILE);
+
+ print Digest::MD5->new->addfile(*FILE)->hexdigest, " $file\n";
+
+Perl 5.8 support Unicode characters in strings. Since the MD5
+algorithm is only defined for strings of bytes, it can not be used on
+strings that contains chars with ordinal number above 255. The MD5
+functions and methods will croak if you try to feed them such input
+data:
+
+ use Digest::MD5 qw(md5_hex);
+
+ my $str = "abc\x{300}";
+ print md5_hex($str), "\n"; # croaks
+ # Wide character in subroutine entry
+
+What you can do is calculate the MD5 checksum of the UTF-8
+representation of such strings. This is achieved by filtering the
+string through encode_utf8() function:
+
+ use Digest::MD5 qw(md5_hex);
+ use Encode qw(encode_utf8);
+
+ my $str = "abc\x{300}";
+ print md5_hex(encode_utf8($str)), "\n";
+ # 8c2d46911f3f5a326455f0ed7a8ed3b3

+=head1 ABSTRACT
+
+Digest::SHA is a complete implementation of the NIST Secure Hash
+Standard. It gives Perl programmers a convenient way to calculate
+SHA-1, SHA-224, SHA-256, SHA-384, and SHA-512 message digests.
+The module can handle all types of input, including partial-byte
+data.
+
+=head1 DESCRIPTION
+
+Digest::SHA is written in C for speed. If your platform lacks a
+C compiler, you can install the functionally equivalent (but much
+slower) L<Digest::SHA::PurePerl> module.
+
+The programming interface is easy to use: it's the same one found
+in CPAN's L<Digest> module. So, if your applications currently
+use L<Digest::MD5> and you'd prefer the stronger security of SHA,
+it's a simple matter to convert them.
+
+The interface provides two ways to calculate digests: all-at-once,
+or in stages. To illustrate, the following short program computes
+the SHA-256 digest of "hello world" using each approach:
+
+ use Digest::SHA qw(sha256_hex);
+
+ $data = "hello world";
+ @frags = split(//, $data);
+
+ # all-at-once (Functional style)
+ $digest1 = sha256_hex($data);
+
+ # in-stages (OOP style)
+ $state = Digest::SHA->new(256);
+ for (@frags) { $state->add($_) }
+ $digest2 = $state->hexdigest;
+
+ print $digest1 eq $digest2 ?
+ "whew!\n" : "oops!\n";
+
+To calculate the digest of an n-bit message where I<n> is not a
+multiple of 8, use the I<add_bits()> method. For example, consider
+the 446-bit message consisting of the bit-string "110" repeated
+148 times, followed by "11". Here's how to display its SHA-1
+digest:
+
+ use Digest::SHA;
+ $bits = "110" x 148 . "11";
+ $sha = Digest::SHA->new(1)->add_bits($bits);
+ print $sha->hexdigest, "\n";
+
+Note that for larger bit-strings, it's more efficient to use the
+two-argument version I<add_bits($data, $nbits)>, where I<$data> is
+in the customary packed binary format used for Perl strings.
+
+The module also lets you save intermediate SHA states to disk, or
+display them on standard output. The I<dump()> method generates
+portable, human-readable text describing the current state of
+computation. You can subsequently retrieve the file with I<load()>
+to resume where the calculation left off.
+
+To see what a state description looks like, just run the following:
+
+ use Digest::SHA;
+ Digest::SHA->new->add("Shaw" x 1962)->dump;
+
+As an added convenience, the Digest::SHA module offers routines to
+calculate keyed hashes using the HMAC-SHA-1/224/256/384/512
+algorithms. These services exist in functional form only, and
+mimic the style and behavior of the I<sha()>, I<sha_hex()>, and
+I<sha_base64()> functions.
+
+ # Test vector from draft-ietf-ipsec-ciph-sha-256-01.txt
+
+ use Digest::SHA qw(hmac_sha256_hex);
+ print hmac_sha256_hex("Hi There", chr(0x0b) x 32), "\n";
+
+=head1 NIST STATEMENT ON SHA-1
+
+I<NIST was recently informed that researchers had discovered a way
+to "break" the current Federal Information Processing Standard SHA-1
+algorithm, which has been in effect since 1994. The researchers
+have not yet published their complete results, so NIST has not
+confirmed these findings. However, the researchers are a reputable
+research team with expertise in this area.>
+
+I<Due to advances in computing power, NIST already planned to phase
+out SHA-1 in favor of the larger and stronger hash functions (SHA-224,
+SHA-256, SHA-384 and SHA-512) by 2010. New developments should use
+the larger and stronger hash functions.>

+=head1 PADDING OF BASE64 DIGESTS
+
+By convention, CPAN Digest modules do B<not> pad their Base64 output.
+Problems can occur when feeding such digests to other software that
+expects properly padded Base64 encodings.
+
+For the time being, any necessary padding must be done by the user.
+Fortunately, this is a simple operation: if the length of a Base64-encoded
+digest isn't a multiple of 4, simply append "=" characters to the end
+of the digest until it is:
+
+ while (length($b64_digest) % 4) {
+ $b64_digest .= '=';
+ }
+
+To illustrate, I<sha256_base64("abc")> is computed to be
+
+ ungWv48Bz+pBQUDeXa4iI7ADYaOWF3qctBD/YfIAFa0
+
+which has a length of 43. So, the properly padded version is
+
+ ungWv48Bz+pBQUDeXa4iI7ADYaOWF3qctBD/YfIAFa0=
+

+None by default.

+Provided your C compiler supports a 64-bit type (e.g. the I<long
+long> of C99, or I<__int64> used by Microsoft C/C++), all of these
+functions will be available for use. Otherwise, you won't be able
+to perform the SHA-384 and SHA-512 transforms, both of which require
+64-bit operations.

+I<OOP style>
+
+=over 4
+
+=item B<new($alg)>
+
+Returns a new Digest::SHA object. Allowed values for I<$alg> are
+1, 224, 256, 384, or 512. It's also possible to use common string
+representations of the algorithm (e.g. "sha256", "SHA-384"). If
+the argument is missing, SHA-1 will be used by default.
+
+Invoking I<new> as an instance method will not create a new object;
+instead, it will simply reset the object to the initial state
+associated with I<$alg>. If the argument is missing, the object
+will continue using the same algorithm that was selected at creation.
+
+=item B<reset($alg)>
+
+This method has exactly the same effect as I<new($alg)>. In fact,
+I<reset> is just an alias for I<new>.
+
+=item B<hashsize>
+
+Returns the number of digest bits for this object. The values are
+160, 224, 256, 384, and 512 for SHA-1, SHA-224, SHA-256, SHA-384,
+and SHA-512, respectively.
+
+=item B<algorithm>
+
+Returns the digest algorithm for this object. The values are 1,
+224, 256, 384, and 512 for SHA-1, SHA-224, SHA-256, SHA-384, and
+SHA-512, respectively.
+
+=item B<clone>
+
+Returns a duplicate copy of the object.
+
+=item B<add($data, ...)>
+
+Logically joins the arguments into a single string, and uses it to
+update the current digest state. In other words, the following
+statements have the same effect:
+
+ $sha->add("a"); $sha->add("b"); $sha->add("c");
+ $sha->add("a")->add("b")->add("c");
+ $sha->add("a", "b", "c");
+ $sha->add("abc");
+
+The return value is the updated object itself.
+
+=item B<add_bits($data, $nbits)>
+
+=item B<add_bits($bits)>
+
+Updates the current digest state by appending bits to it. The
+return value is the updated object itself.
+
+The first form causes the most-significant I<$nbits> of I<$data>
+to be appended to the stream. The I<$data> argument is in the
+customary binary format used for Perl strings.
+
+The second form takes an ASCII string of "0" and "1" characters as
+its argument. It's equivalent to
+
+ $sha->add_bits(pack("B*", $bits), length($bits));
+
+So, the following two statements do the same thing:
+
+ $sha->add_bits("111100001010");
+ $sha->add_bits("\xF0\xA0", 12);
+
+=item B<addfile(*FILE)>
+
+Reads from I<FILE> until EOF, and appends that data to the current
+state. The return value is the updated object itself.
+
+=item B<addfile($filename [, $mode])>
+
+Reads the contents of I<$filename>, and appends that data to the current
+state. The return value is the updated object itself.
+
+By default, I<$filename> is simply opened and read; no special modes
+or I/O disciplines are used. To change this, set the optional I<$mode>
+argument to one of the following values:
+
+ "b" read file in binary mode
+
+ "p" use portable mode
+
+The "p" mode is handy since it ensures that the digest value of
+I<$filename> will be the same when computed on different operating
+systems. It accomplishes this by internally translating all newlines in
+text files to UNIX format before calculating the digest. Binary files
+are read in raw mode with no translation whatsoever.
+
+For a fuller discussion of newline formats, refer to CPAN module
+L<File::LocalizeNewlines>. Its "universal line separator" regex forms
+the basis of I<addfile>'s portable mode processing.
+
+=item B<dump($filename)>
+
+Provides persistent storage of intermediate SHA states by writing
+a portable, human-readable representation of the current state to
+I<$filename>. If the argument is missing, or equal to the empty
+string, the state information will be written to STDOUT.
+
+=item B<load($filename)>
+
+Returns a Digest::SHA object representing the intermediate SHA
+state that was previously dumped to I<$filename>. If called as a
+class method, a new object is created; if called as an instance
+method, the object is reset to the state contained in I<$filename>.
+If the argument is missing, or equal to the empty string, the state
+information will be read from STDIN.
+
+=item B<digest>
+
+Returns the digest encoded as a binary string.
+
+Note that the I<digest> method is a read-once operation. Once it
+has been performed, the Digest::SHA object is automatically reset
+in preparation for calculating another digest value. Call
+I<$sha-E<gt>clone-E<gt>digest> if it's necessary to preserve the
+original digest state.
+
+=item B<hexdigest>
+
+Returns the digest encoded as a hexadecimal string.
+
+Like I<digest>, this method is a read-once operation. Call
+I<$sha-E<gt>clone-E<gt>hexdigest> if it's necessary to preserve
+the original digest state.
+
+This method is inherited if L<Digest::base> is installed on your
+system. Otherwise, a functionally equivalent substitute is used.
+
+=item B<b64digest>
+
+Returns the digest encoded as a Base64 string.
+
+Like I<digest>, this method is a read-once operation. Call

+=head1 DESCRIPTION
+
+The C<Digest::SHA1> module allows you to use the NIST SHA-1 message
+digest algorithm from within Perl programs. The algorithm takes as
+input a message of arbitrary length and produces as output a 160-bit
+"fingerprint" or "message digest" of the input.
+
+In 2005, security flaws were identified in SHA-1, namely that a possible
+mathematical weakness might exist, indicating that a stronger hash function
+would be desirable. The L<Digest::SHA> module implements the stronger
+algorithms in the SHA family.
+
+The C<Digest::SHA1> module provide a procedural interface for simple
+use, as well as an object oriented interface that can handle messages
+of arbitrary length and which can read files directly.
+
+=head1 FUNCTIONS
+
+The following functions can be exported from the C<Digest::SHA1>
+module. No functions are exported by default.
+
+=over 4
+
+=item sha1($data,...)
+
+This function will concatenate all arguments, calculate the SHA-1
+digest of this "message", and return it in binary form. The returned
+string will be 20 bytes long.
+
+The result of sha1("a", "b", "c") will be exactly the same as the
+result of sha1("abc").
+
+=item sha1_hex($data,...)
+
+Same as sha1(), but will return the digest in hexadecimal form. The
+length of the returned string will be 40 and it will only contain
+characters from this set: '0'..'9' and 'a'..'f'.
+
+=item sha1_base64($data,...)
+
+Same as sha1(), but will return the digest as a base64 encoded string.
+The length of the returned string will be 27 and it will only contain
+characters from this set: 'A'..'Z', 'a'..'z', '0'..'9', '+' and
+'/'.
+
+Note that the base64 encoded string returned is not padded to be a
+multiple of 4 bytes long. If you want interoperability with other
+base64 encoded sha1 digests you might want to append the redundant
+string "=" to the result.
+
+=item sha1_transform($data)
+
+Implements the basic SHA1 transform on a 64 byte block. The $data
+argument and the returned $digest are in binary form. This algorithm
+is used in NIST FIPS 186-2
+
+=back
+
+=head1 METHODS
+
+The object oriented interface to C<Digest::SHA1> is described in this
+section. After a C<Digest::SHA1> object has been created, you will add
+data to it and finally ask for the digest in a suitable format. A
+single object can be used to calculate multiple digests.
+
+The following methods are provided:
+
+=over 4
+
+=item $sha1 = Digest::SHA1->new
+
+The constructor returns a new C<Digest::SHA1> object which encapsulate
+the state of the SHA-1 message-digest algorithm.
+
+If called as an instance method (i.e. $sha1->new) it will just reset the
+state the object to the state of a newly created object. No new
+object is created in this case.
+
+=item $sha1->reset
+
+This is just an alias for $sha1->new.
+
+=item $sha1->clone
+
+This a copy of the $sha1 object. It is useful when you do not want to
+destroy the digests state, but need an intermediate value of the
+digest, e.g. when calculating digests iteratively on a continuous data
+stream. Example:
+
+ my $sha1 = Digest::SHA1->new;
+ while (<>) {
+ $sha1->add($_);
+ print "Line $.: ", $sha1->clone->hexdigest, "\n";
+ }
+
+=item $sha1->add($data,...)
+
+The $data provided as argument are appended to the message we
+calculate the digest for. The return value is the $sha1 object itself.
+
+All these lines will have the same effect on the state of the $sha1
+object:
+
+ $sha1->add("a"); $sha1->add("b"); $sha1->add("c");
+ $sha1->add("a")->add("b")->add("c");
+ $sha1->add("a", "b", "c");
+ $sha1->add("abc");
+
+=item $sha1->addfile($io_handle)
+
+The $io_handle will be read until EOF and its content appended to the
+message we calculate the digest for. The return value is the $sha1
+object itself.
+
+The addfile() method will croak() if it fails reading data for some
+reason. If it croaks it is unpredictable what the state of the $sha1
+object will be in. The addfile() method might have been able to read
+the file partially before it failed. It is probably wise to discard
+or reset the $sha1 object if this occurs.
+
+In most cases you want to make sure that the $io_handle is in
+C<binmode> before you pass it as argument to the addfile() method.
+
+=item $sha1->add_bits($data, $nbits)
+
+=item $sha1->add_bits($bitstring)
+
+This implementation of SHA-1 only supports byte oriented input so you
+might only add bits as multiples of 8. If you need bit level support
+please consider using the C<Digest::SHA> module instead. The
+add_bits() method is provided here for compatibility with other digest
+implementations. See L<Digest> for description of the arguments that
+add_bits() take.
+
+=item $sha1->digest
+
+Return the binary digest for the message. The returned string will be
+20 bytes long.
+
+Note that the C<digest> operation is effectively a destructive,
+read-once operation. Once it has been performed, the C<Digest::SHA1>
+object is automatically C<reset> and can be used to calculate another
+digest value. Call $sha1->clone->digest if you want to calculate the
+digest without reseting the digest state.
+
+=item $sha1->hexdigest
+
+Same as $sha1->digest, but will return the digest in hexadecimal
+form. The length of the returned string will be 40 and it will only
+contain characters from this set: '0'..'9' and 'a'..'f'.
+
+=item $sha1->b64digest
+
+Same as $sha1->digest, but will return the digest as a base64 encoded
+string. The length of the returned string will be 27 and it will only
+contain characters from this set: 'A'..'Z', 'a'..'z', '0'..'9', '+'
+and '/'.
+
+
+The base64 encoded string returned is not padded to be a multiple of 4
+bytes long. If you want interoperability with other base64 encoded
+SHA-1 digests you might want to append the string "=" to the result.

+This function will calculate and return the binary digest of the bytes
+of the given file. The function will croak if it fails to open or
+read the file.
+
+The $algorithm is a string like "MD2", "MD5", "SHA-1", "SHA-512".
+Additional arguments are passed to the constructor for the
+implementation of the given algorithm.
+
+=item digest_file_hex( $file, $algorithm, [$arg,...] )
+
+Same as digest_file(), but return the digest in hex form.
+
+=item digest_file_base64( $file, $algorithm, [$arg,...] )
+
+Same as digest_file(), but return the digest as a base64 encoded
+string.
