Package cts

Package cts implements the ciphertext stealing (CTS) mode of operation for block ciphers. The implementation uses the CTS-3 (Kerberos) variant for formatting the cipher text.

DecryptAES128 decrypts the data that is encrypted in AES-CTS mode. The key specifies the AES encryption key and iv is the random initialization vector used in encryption.

EncryptAES128 encrypts the data in AES-CTS mode. The key specifies the AES encryption key and iv is a random initialization vector.
