NAME
Crypt::Digest::Tiger192 - Hash function Tiger-192 [size: 192 bits]

SYNOPSIS
   ### Functional interface:
   use Crypt::Digest::Tiger192 qw( tiger192 tiger192_hex tiger192_b64 tiger192_b64u
                                tiger192_file tiger192_file_hex tiger192_file_b64 tiger192_file_b64u );

   # calculate digest from string/buffer
   $tiger192_raw  = tiger192('data string');
   $tiger192_hex  = tiger192_hex('data string');
   $tiger192_b64  = tiger192_b64('data string');
   $tiger192_b64u = tiger192_b64u('data string');
   # calculate digest from file
   $tiger192_raw  = tiger192_file('filename.dat');
   $tiger192_hex  = tiger192_file_hex('filename.dat');
   $tiger192_b64  = tiger192_file_b64('filename.dat');
   $tiger192_b64u = tiger192_file_b64u('filename.dat');
   # calculate digest from filehandle
   $tiger192_raw  = tiger192_file(*FILEHANDLE);
   $tiger192_hex  = tiger192_file_hex(*FILEHANDLE);
   $tiger192_b64  = tiger192_file_b64(*FILEHANDLE);
   $tiger192_b64u = tiger192_file_b64u(*FILEHANDLE);

   ### OO interface:
   use Crypt::Digest::Tiger192;

   $d = Crypt::Digest::Tiger192->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 Tiger192 digest algorithm.

EXPORT
Nothing is exported by default.

You can export selected functions:

  use Crypt::Digest::Tiger192 qw(tiger192 tiger192_hex tiger192_b64 tiger192_b64u
                                      tiger192_file tiger192_file_hex tiger192_file_b64 tiger192_file_b64u);

Or all of them at once:

  use Crypt::Digest::Tiger192 ':all';

FUNCTIONS

  tiger192
Logically joins all arguments into a single string, and returns its Tiger192 digest encoded as a binary string.

 $tiger192_raw = tiger192('data string');
 #or
 $tiger192_raw = tiger192('any data', 'more data', 'even more data');

  tiger192_hex
Logically joins all arguments into a single string, and returns its Tiger192 digest encoded as a hexadecimal string.

 $tiger192_hex = tiger192_hex('data string');
 #or
 $tiger192_hex = tiger192_hex('any data', 'more data', 'even more data');

  tiger192_b64
Logically joins all arguments into a single string, and returns its Tiger192 digest encoded as a Base64 string, with trailing '=' padding.

 $tiger192_b64 = tiger192_b64('data string');
 #or
 $tiger192_b64 = tiger192_b64('any data', 'more data', 'even more data');

  tiger192_b64u
Logically joins all arguments into a single string, and returns its Tiger192 digest encoded as a Base64 URL Safe string (see RFC 4648 section 5).

 $tiger192_b64url = tiger192_b64u('data string');
 #or
 $tiger192_b64url = tiger192_b64u('any data', 'more data', 'even more data');

  tiger192_file
Reads file (defined by filename or filehandle) content, and returns its Tiger192 digest encoded as a binary string.

 $tiger192_raw = tiger192_file('filename.dat');
 #or
 $tiger192_raw = tiger192_file(*FILEHANDLE);

  tiger192_file_hex
Reads file (defined by filename or filehandle) content, and returns its Tiger192 digest encoded as a hexadecimal string.

 $tiger192_hex = tiger192_file_hex('filename.dat');
 #or
 $tiger192_hex = tiger192_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.

  tiger192_file_b64
Reads file (defined by filename or filehandle) content, and returns its Tiger192 digest encoded as a Base64 string, with trailing '=' padding.

 $tiger192_b64 = tiger192_file_b64('filename.dat');
 #or
 $tiger192_b64 = tiger192_file_b64(*FILEHANDLE);

  tiger192_file_b64u
Reads file (defined by filename or filehandle) content, and returns its Tiger192 digest encoded as a Base64 URL Safe string (see RFC 4648 section 5).

 $tiger192_b64url = tiger192_file_b64u('filename.dat');
 #or
 $tiger192_b64url = tiger192_file_b64u(*FILEHANDLE);

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

  new
 $d = Crypt::Digest::Tiger192->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::Tiger192->hashsize();
 #or
 Crypt::Digest::Tiger192::hashsize();

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

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

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

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