Crypt::TC18 1.0.0

Crypt::TC18 is a Crypt::CBC compliant block cipher.

ABSTRACT

TC18 is 128-bit block cipher that accepts a 64-bit key. TC18 is also known as XSM.

SYNOPSIS

    use Crypt::TC18;

    $cipher = new Crypt::TC18 $key;

    $ciphertext = $cipher->encrypt($plaintext);
    $plaintext  = $cipher->decrypt($ciphertext);

    $bs = $cipher->blocksize;
    $ks = $cipher->keysize;
    $r = $cipher->rounds;

TC18 is 128-bit block cipher that accepts a 64-bit key. It was designed by Tom St. Denis.

This module supports the Crypt::CBC interface, with the following functions.
Functions

blocksize

    Returns the size (in bytes) of the block (16, in this case)
keysize

    Returns the size (in bytes) of the key (8, in this case)
rounds

    Returns the number of rounds used by TC18 (16, in this case)
encrypt($data)

    Encrypts 16 bytes of $data and returns the corresponding ciphertext
decrypt($data)

    Decrypts 16 bytes of $data and returns the corresponding plaintext
