- * Trouble with Ciphertext Stealing, CTS, mode is that there is no
- * common official specification, but couple of cipher/application
- * specific ones: RFC2040 and RFC3962. Then there is 'Proposal to
- * Extend CBC Mode By "Ciphertext Stealing"' at NIST site, which
- * deviates from mentioned RFCs. Most notably it allows input to be
- * of block length and it doesn't flip the order of the last two
- * blocks. CTS is being discussed even in ECB context, but it's not
- * adopted for any known application. This implementation provides
- * two interfaces: one compliant with above mentioned RFCs and one
- * compliant with the NIST proposal, both extending CBC mode.
