NAME

Crypt::CAST5 - CAST5 encryption library

SYNOPSIS

use Crypt::CAST5;

my Crypt::CAST5 $cast5   .= new: 'ayy lmao'.encode;
my Str          $in       = 'sup my dudes';
my Blob         $encoded  = $cast5.encode: $in.encode;
my Blob         $decoded  = $cast5.decode: $encoded;
my Str          $out      = $decoded.decode;

say $out; # OUTPUT: sup my dudes

DESCRIPTION

Warning: this implementation is naive and is not implemented in constant time, thus it is vulnerable to side channel attacks. Do not use this library for any serious applications as it stands now!

Crypt::CAST5 is a library that handles encryption and decryption using the CAST5 algorithm. Currently, only the ECB block cipher mode is supported.

METHODS

Constructs a new instance of Crypt::CAST5 using the given block cipher mode and key. The key must be 5-16 bytes in length.

Encodes $plaintext using CAST5 encryption.

Decodes $ciphertext using CAST5 encryption.
