* Ciphertext stealing encrypts plaintext using a block cipher, without padding
* the message to a multiple of the block size, so the ciphertext is the same
* size as the plaintext.
* It does this by altering processing of the last two blocks of the message.
* The processing of all but the last two blocks is unchanged, but a portion of
* the second-last block's ciphertext is "stolen" to pad the last plaintext
* block. The padded final block is then encrypted as usual.
* The final ciphertext for the last two blocks, consists of the partial block
* (with the "stolen" portion omitted) plus the full final block,
* which are the same size as the original plaintext.
* Decryption requires decrypting the final block first, then restoring the
* stolen ciphertext to the partial block, which can then be decrypted as usual.
* AES_CBC_CTS has 3 variants:
* (1) CS1 The NIST variant.
* If the length is a multiple of the blocksize it is the same as CBC mode.
* otherwise it produces C1||C2||(C(n-1))*||Cn.
* Where C(n-1)* is a partial block.
* (2) CS2
* If the length is a multiple of the blocksize it is the same as CBC mode.
* otherwise it produces C1||C2||Cn||(C(n-1))*.
* Where C(n-1)* is a partial block.
* (3) CS3 The Kerberos5 variant.
* Produces C1||C2||Cn||(C(n-1))* regardless of the length.
* If the length is a multiple of the blocksize it looks similar to CBC mode
* with the last 2 blocks swapped.
* Otherwise it is the same as CS2.
