Crypt::Digest::MD5(3) User Contributed Perl DocumentationCrypt::Digest::MD5(3)

NAME
       Crypt::Digest::MD5 - Hash function MD5 [size: 128 bits]

SYNOPSIS
	  ### Functional interface:
	  use Crypt::Digest::MD5 qw( md5 md5_hex md5_b64 md5_b64u
				       md5_file	md5_file_hex md5_file_b64 md5_file_b64u	);

	  # calculate digest from string/buffer
	  $md5_raw  = md5('data	string');
	  $md5_hex  = md5_hex('data string');
	  $md5_b64  = md5_b64('data string');
	  $md5_b64u = md5_b64u('data string');
	  # calculate digest from file
	  $md5_raw  = md5_file('filename.dat');
	  $md5_hex  = md5_file_hex('filename.dat');
	  $md5_b64  = md5_file_b64('filename.dat');
	  $md5_b64u = md5_file_b64u('filename.dat');
	  # calculate digest from filehandle
	  $md5_raw  = md5_file(*FILEHANDLE);
	  $md5_hex  = md5_file_hex(*FILEHANDLE);
	  $md5_b64  = md5_file_b64(*FILEHANDLE);
	  $md5_b64u = md5_file_b64u(*FILEHANDLE);

	  ### OO interface:
	  use Crypt::Digest::MD5;

	  $d = Crypt::Digest::MD5->new;
	  $d->add('any data');
	  $d->addfile('filename.dat');
	  $d->addfile(*FILEHANDLE);
	  $result_raw  = $d->digest;	 # raw bytes
	  $result_hex  = $d->hexdigest;	 # hexadecimal form
	  $result_b64  = $d->b64digest;	 # Base64 form
	  $result_b64u = $d->b64udigest; # Base64 URL Safe form

DESCRIPTION
       Provides	an interface to	the MD5	digest algorithm.

EXPORT
       Nothing is exported by default.

       You can export selected functions:

	 use Crypt::Digest::MD5	qw(md5 md5_hex md5_b64 md5_b64u
					     md5_file md5_file_hex md5_file_b64	md5_file_b64u);

       Or all of them at once:

	 use Crypt::Digest::MD5	':all';

FUNCTIONS
   md5
       Logically joins all arguments into a single string, and returns its MD5
       digest encoded as a binary string.

	$md5_raw = md5('data string');
	#or
	$md5_raw = md5('any data', 'more data',	'even more data');

   md5_hex
       Logically joins all arguments into a single string, and returns its MD5
       digest encoded as a hexadecimal string.

	$md5_hex = md5_hex('data string');
	#or
	$md5_hex = md5_hex('any	data', 'more data', 'even more data');

   md5_b64
       Logically joins all arguments into a single string, and returns its MD5
       digest encoded as a Base64 string, with trailing	'=' padding.

	$md5_b64 = md5_b64('data string');
	#or
	$md5_b64 = md5_b64('any	data', 'more data', 'even more data');

   md5_b64u
       Logically joins all arguments into a single string, and returns its MD5
       digest encoded as a Base64 URL Safe string (see RFC 4648	section	5).

	$md5_b64url = md5_b64u('data string');
	#or
	$md5_b64url = md5_b64u('any data', 'more data',	'even more data');

   md5_file
       Reads file (defined by filename or filehandle) content, and returns its
       MD5 digest encoded as a binary string.

	$md5_raw = md5_file('filename.dat');
	#or
	$md5_raw = md5_file(*FILEHANDLE);

   md5_file_hex
       Reads file (defined by filename or filehandle) content, and returns its
       MD5 digest encoded as a hexadecimal string.

	$md5_hex = md5_file_hex('filename.dat');
	#or
	$md5_hex = md5_file_hex(*FILEHANDLE);

       BEWARE: You have	to make	sure that the filehandle is in binary mode
       before you pass it as argument to the addfile() method.

   md5_file_b64
       Reads file (defined by filename or filehandle) content, and returns its
       MD5 digest encoded as a Base64 string, with trailing '='	padding.

	$md5_b64 = md5_file_b64('filename.dat');
	#or
	$md5_b64 = md5_file_b64(*FILEHANDLE);

   md5_file_b64u
       Reads file (defined by filename or filehandle) content, and returns its
       MD5 digest encoded as a Base64 URL Safe string (see RFC 4648 section
       5).

	$md5_b64url = md5_file_b64u('filename.dat');
	#or
	$md5_b64url = md5_file_b64u(*FILEHANDLE);

METHODS
       The OO interface	provides the same set of functions as Crypt::Digest.

   new
	$d = Crypt::Digest::MD5->new();

   clone
	$d->clone();

   reset
	$d->reset();

   add
	$d->add('any data');
	#or
	$d->add('any data', 'more data', 'even more data');

   addfile
	$d->addfile('filename.dat');
	#or
	$d->addfile(*FILEHANDLE);

   add_bits
	$d->add_bits($bit_string);   # e.g. $d->add_bits("111100001010");
	#or
	$d->add_bits($data, $nbits); # e.g. $d->add_bits("\xF0\xA0", 16);

   hashsize
	$d->hashsize;
	#or
	Crypt::Digest::MD5->hashsize();
	#or
	Crypt::Digest::MD5::hashsize();

   digest
	$result_raw = $d->digest();

   hexdigest
	$result_hex = $d->hexdigest();

   b64digest
	$result_b64 = $d->b64digest();

   b64udigest
	$result_b64url = $d->b64udigest();
