NAME

Crypt::TC18 - Crypt::CBC compliant block cipher

ABSTRACT

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

    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.

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
