          ### 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();
