   # calculate digest from filehandle
   $ripemd160_raw  = ripemd160_file(*FILEHANDLE);
   $ripemd160_hex  = ripemd160_file_hex(*FILEHANDLE);
   $ripemd160_b64  = ripemd160_file_b64(*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);
