NAME
       Crypt::Digest::RIPEMD160 - Hash function RIPEMD-160 [size: 160 bits]

SYNOPSIS
          ### Functional interface:
          use Crypt::Digest::RIPEMD160 qw( ripemd160 ripemd160_hex ripemd160_b64 ripemd160_b64u
                                       ripemd160_file ripemd160_file_hex ripemd160_file_b64 ripemd160_file_b64u );

          # calculate digest from string/buffer
          $ripemd160_raw  = ripemd160('data string');
          $ripemd160_hex  = ripemd160_hex('data string');
          $ripemd160_b64  = ripemd160_b64('data string');
          $ripemd160_b64u = ripemd160_b64u('data string');
          # calculate digest from file
          $ripemd160_raw  = ripemd160_file('filename.dat');
          $ripemd160_hex  = ripemd160_file_hex('filename.dat');
          $ripemd160_b64  = ripemd160_file_b64('filename.dat');
          $ripemd160_b64u = ripemd160_file_b64u('filename.dat');
          # calculate digest from filehandle
          $ripemd160_raw  = ripemd160_file(*FILEHANDLE);
          $ripemd160_hex  = ripemd160_file_hex(*FILEHANDLE);
          $ripemd160_b64  = ripemd160_file_b64(*FILEHANDLE);
          $ripemd160_b64u = ripemd160_file_b64u(*FILEHANDLE);

          ### OO interface:
          use Crypt::Digest::RIPEMD160;

          $d = Crypt::Digest::RIPEMD160->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 RIPEMD160 digest algorithm.

EXPORT
       Nothing is exported by default.

       You can export selected functions:

         use Crypt::Digest::RIPEMD160 qw(ripemd160 ripemd160_hex ripemd160_b64 ripemd160_b64u
                                             ripemd160_file ripemd160_file_hex ripemd160_file_b64 ripemd160_file_b64u);

       Or all of them at once:

         use Crypt::Digest::RIPEMD160 ':all';

FUNCTIONS
   ripemd160
       Logically joins all arguments into a single string, and returns its
       RIPEMD160 digest encoded as a binary string.

        $ripemd160_raw = ripemd160('data string');
        #or
        $ripemd160_raw = ripemd160('any data', 'more data', 'even more data');

   ripemd160_hex
       Logically joins all arguments into a single string, and returns its
       RIPEMD160 digest encoded as a hexadecimal string.

        $ripemd160_hex = ripemd160_hex('data string');
        #or
        $ripemd160_hex = ripemd160_hex('any data', 'more data', 'even more data');

   ripemd160_b64
       Logically joins all arguments into a single string, and returns its
       RIPEMD160 digest encoded as a Base64 string, with trailing '=' padding.

        $ripemd160_b64 = ripemd160_b64('data string');
        #or
        $ripemd160_b64 = ripemd160_b64('any data', 'more data', 'even more data');

   ripemd160_b64u
       Logically joins all arguments into a single string, and returns its
       RIPEMD160 digest encoded as a Base64 URL Safe string (see RFC 4648
       section 5).

        $ripemd160_b64url = ripemd160_b64u('data string');
        #or
        $ripemd160_b64url = ripemd160_b64u('any data', 'more data', 'even more data');

   ripemd160_file
       Reads file (defined by filename or filehandle) content, and returns its
       RIPEMD160 digest encoded as a binary string.

        $ripemd160_raw = ripemd160_file('filename.dat');
        #or
        $ripemd160_raw = ripemd160_file(*FILEHANDLE);

   ripemd160_file_hex
       Reads file (defined by filename or filehandle) content, and returns its
       RIPEMD160 digest encoded as a hexadecimal string.

        $ripemd160_hex = ripemd160_file_hex('filename.dat');
        #or
        $ripemd160_hex = ripemd160_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.

   ripemd160_file_b64
       Reads file (defined by filename or filehandle) content, and returns its
       RIPEMD160 digest encoded as a Base64 string, with trailing '=' padding.

        $ripemd160_b64 = ripemd160_file_b64('filename.dat');
        #or
        $ripemd160_b64 = ripemd160_file_b64(*FILEHANDLE);

   ripemd160_file_b64u
       Reads file (defined by filename or filehandle) content, and returns its
       RIPEMD160 digest encoded as a Base64 URL Safe string (see RFC 4648
       section 5).

        $ripemd160_b64url = ripemd160_file_b64u('filename.dat');
        #or
        $ripemd160_b64url = ripemd160_file_b64u(*FILEHANDLE);
