[![Build Status](https://travis-ci.org/Kaiepi/p6-Crypt-CAST5.svg?branch=master)](https://travis-ci.org/Kaiepi/p6-Crypt-CAST5) 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 $out; # OUTPUT: sup my dudes DESCRIPTION =========== **Warning: this implementation is naive and is not implemented in constant time, thus it is vulnerable to side channel attacks. Do not use this library for any serious applications as it stands now!** Crypt::CAST5 is a library that handles encryption and decryption using the CAST5 algorithm. Currently, only the ECB block cipher mode is supported. METHODS ======= * **new**(Blob *$key*) Constructs a new instance of Crypt::CAST5 using the given block cipher mode and key. The key must be 5-16 bytes in length. * **encode**(Blob *$plaintext* --> Blob) Encodes `$plaintext` using CAST5 encryption. * **decode**(Blob *$ciphertext* --> Blob) Decodes `$ciphertext` using CAST5 encryption.
