+
+Digest - Modules that calculate message digests
+
+=head1 SYNOPSIS
+
+ $md5 = Digest->new("MD5");
+ $sha1 = Digest->new("SHA-1");
+ $sha256 = Digest->new("SHA-256");
+ $sha384 = Digest->new("SHA-384");
+ $sha512 = Digest->new("SHA-512");
+
+ $hmac = Digest->HMAC_MD5($key);
+
+=head1 DESCRIPTION
+
+The C<Digest::> modules calculate digests, also called "fingerprints"
+or "hashes", of some data, called a message. The digest is (usually)
+some small/fixed size string. The actual size of the digest depend of
+the algorithm used. The message is simply a sequence of arbitrary
+bytes or bits.
+
+An important property of the digest algorithms is that the digest is
+I<likely> to change if the message change in some way. Another
+property is that digest functions are one-way functions, that is it
+should be I<hard> to find a message that correspond to some given
+digest. Algorithms differ in how "likely" and how "hard", as well as
+how efficient they are to compute.
+
+Note that the properties of the algorithms change over time, as the
+algorithms are analyzed and machines grow faster. If your application
+for instance depends on it being "impossible" to generate the same
+digest for a different message it is wise to make it easy to plug in
+stronger algorithms as the one used grow weaker. Using the interface
+documented here should make it easy to change algorithms later.
+
+All C<Digest::> modules provide the same programming interface. A
+functional interface for simple use, as well as an object oriented
+interface that can handle messages of arbitrary length and which can
+read files directly.
+
+The digest can be delivered in three formats:
+
+=over 8
+
+=item I<binary>
+
+This is the most compact form, but it is not well suited for printing
+or embedding in places that can't handle arbitrary data.
+
+=item I<hex>
+
+A twice as long string of lowercase hexadecimal digits.
+
+=item I<base64>
+
+A string of portable printable characters. This is the base64 encoded
+representation of the digest with any trailing padding removed. The
+string will be about 30% longer than the binary version.
+L<MIME::Base64> tells you more about this encoding.
+
+=back
+
+
+The functional interface is simply importable functions with the same
+name as the algorithm. The functions take the message as argument and
+return the digest. Example:
+
+ use Digest::MD5 qw(md5);
+ $digest = md5($message);
+
+There are also versions of the functions with "_hex" or "_base64"
+appended to the name, which returns the digest in the indicated form.
+
+=head1 OO INTERFACE
+
+The following methods are available for all C<Digest::> modules:
+
+=over 4
+
+=item $ctx = Digest->XXX($arg,...)
+
+=item $ctx = Digest->new(XXX => $arg,...)
+
+=item $ctx = Digest::XXX->new($arg,...)
+
+The constructor returns some object that encapsulate the state of the
+message-digest algorithm. You can add data to the object and finally
+ask for the digest. The "XXX" should of course be replaced by the proper
+name of the digest algorithm you want to use.
+
+The two first forms are simply syntactic sugar which automatically
+load the right module on first use. The second form allow you to use
+algorithm names which contains letters which are not legal perl
+identifiers, e.g. "SHA-1". If no implementation for the given algorithm
+can be found, then an exception is raised.
+
+If new() is called as an instance method (i.e. $ctx->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, and the return value is the
+reference to the object (i.e. $ctx).
+
+=item $other_ctx = $ctx->clone
+
+The clone method creates a copy of the digest state object and returns
+a reference to the copy.
+
+=item $ctx->reset
+
+This is just an alias for $ctx->new.
+
+=item $ctx->add( $data )
+
+=item $ctx->add( $chunk1, $chunk2, ... )
+
+The string value of the $data provided as argument is appended to the
+message we calculate the digest for. The return value is the $ctx
+object itself.
+
+If more arguments are provided then they are all appended to the
+message, thus all these lines will have the same effect on the state
+of the $ctx object:
+
+ $ctx->add("a"); $ctx->add("b"); $ctx->add("c");
+ $ctx->add("a")->add("b")->add("c");
+ $ctx->add("a", "b", "c");
+ $ctx->add("abc");
+
+Most algorithms are only defined for strings of bytes and this method
+might therefore croak if the provided arguments contain chars with
+ordinal number above 255.
+
+=item $ctx->addfile( $io_handle )
+
+The $io_handle is read until EOF and the content is appended to the
+message we calculate the digest for. The return value is the $ctx
+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 $ctx
+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 $ctx object if this occurs.
+
+In most cases you want to make sure that the $io_handle is in
+"binmode" before you pass it as argument to the addfile() method.
+
+=item $ctx->add_bits( $data, $nbits )
+
+=item $ctx->add_bits( $bitstring )
+
+The add_bits() method is an alternative to add() that allow partial
+bytes to be appended to the message. Most users should just ignore
+this method as partial bytes is very unlikely to be of any practical
+use.
+
+The two argument form of add_bits() will add the first $nbits bits
+from $data. For the last potentially partial byte only the high order
+C<< $nbits % 8 >> bits are used. If $nbits is greater than C<<
+length($data) * 8 >>, then this method would do the same as C<<
+$ctx->add($data) >>.
+
+The one argument form of add_bits() takes a $bitstring of "1" and "0"
+chars as argument. It's a shorthand for C<< $ctx->add_bits(pack("B*",
+$bitstring), length($bitstring)) >>.
+
+The return value is the $ctx object itself.
+
+This example shows two calls that should have the same effect:
+
+ $ctx->add_bits("111100001010");
+ $ctx->add_bits("\xF0\xA0", 12);
+
+Most digest algorithms are byte based and for these it is not possible
+to add bits that are not a multiple of 8, and the add_bits() method
+will croak if you try.
+
+=item $ctx->digest
+
+Return the binary digest for the message.
+
+Note that the C<digest> operation is effectively a destructive,
+read-once operation. Once it has been performed, the $ctx object is
+automatically C<reset> and can be used to calculate another digest
+value. Call $ctx->clone->digest if you want to calculate the digest
+without resetting the digest state.
+
+=item $ctx->hexdigest
+
+Same as $ctx->digest, but will return the digest in hexadecimal form.
+
+=item $ctx->b64digest
+
+Same as $ctx->digest, but will return the digest as a base64 encoded
+string.
+
+=back
+
+=head1 Digest speed
+
+This table should give some indication on the relative speed of
+different algorithms. It is sorted by throughput based on a benchmark
+done with of some implementations of this API:

+
+These numbers was achieved Apr 2004 with ActivePerl-5.8.3 running

+pure perl implementations of the algorithms, which explains why they
+are so slow.

+=head1 NAME
+
+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);
+ $digest = md5_base64($data);
+
+ # OO style
+ use Digest::MD5;
+
+ $ctx = Digest::MD5->new;
+
+ $ctx->add($data);
+ $ctx->addfile(*FILE);
+
+ $digest = $ctx->digest;
+ $digest = $ctx->hexdigest;
+ $digest = $ctx->b64digest;
+
+=head1 DESCRIPTION
+
+The C<Digest::MD5> module allows you to use the RSA Data Security
+Inc. MD5 Message Digest algorithm from within Perl programs. The
+algorithm takes as input a message of arbitrary length and produces as
+output a 128-bit "fingerprint" or "message digest" of the input.
+
+Note that the MD5 algorithm is not as strong as it used to be. It has
+since 2005 been easy to generate different messages that produce the
+same MD5 digest. It still seems hard to generate messages that
+produce a given digest, but it is probably wise to move to stronger
+algorithms for applications that depend on the digest to uniquely identify
+a message.
+
+The C<Digest::MD5> module provide a procedural interface for simple
+use, as well as an object oriented interface that can handle messages
+of arbitrary length and which can read files directly.
+
+=head1 FUNCTIONS
+
+The following functions are provided by the C<Digest::MD5> module.
+None of these functions are exported by default.
+
+=over 4
+
+=item md5($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
