Class NistMCT

java.lang.Object
  gnu.crypto.tool.NistMCT

public class NistMCT

extends java.lang.Object

For a designated symmetric block cipher algorithm, this command generates and exercises Monte Carlo Tests data for both Encryption and Decryption in Electronic Codebook (ECB) and Cipher Block Chaining (CBC) modes.

NistMCT's output file format is in conformance with the layout described in Section 4 of NIST's document "Description of Known Answer Tests and Monte Carlo Tests for Advanced Encryption Standard (AES) Candidate Algorithm Submissions" dated January 7, 1998.

Method Detail

main

public static void main(java.lang.String[] args)

The main entry point for the tool.

 Usage:
    gnu.crypto.tool.NistKat (options) cipher [key-size]

 Where:
    cipher
       The canonical name of the cipher algorithm.
    key-size
       The key-size in bits to use for the algorithm.  If unspecified,
       then the three NIST key-sizes 128, 192 and 256 shall be used.

 Options:
    -E | -C | -A
       Generate Monte Carlo Test (MCT) data for ECB mode only, CBC mode
       only, or both.  For backward compatibility, if this option is
       unspecified, then -A (both modes) is activated.
    -e | -d | -a
       Generate Monte Carlo Test (MCT) data for a designated cipher in
       the selected mode(s), for Encryption only, Decryption only, or
       both.  For backward compatibility, if this option is unspecified,
       then -a (both states) is activated.
