📝 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);

⚙️ 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);
