I am wondering: what is the most common, or most used, block cipher mode used that goes with CTS (CypherText Stealing)?

Is it or ?

    $\begingroup$ You should not use ECB at all (it is insecure), so I hope it is not "usual". $\endgroup$ Mar 8, 2013 at 20:24

There is a NIST definition of CTS (CipherText Stealing) mode in the addendum to NISTSP800-38A.

The title of that addendum answers the question:

"Recommendation for Block Cipher Modes of Operation: Three Variants of Ciphertext Stealing for CBC Mode".

The paper is also useful to understand that there are many different ways to do ciphertext stealing.
