The MARS encryption algorithm (AES candidate) (Menu Crypt/Decrypt \ Symmetric (modern) \ Further)

The MARS encryption algorithm works with a block length of 128 bits and a variable key length, which can be 128, 192 or 256 bits.

The key is entered in the Key entry dialog.

CrypTool contains a tool which performs a Brute-force attack on the MARS encryption algorithm.
