Detailed Description

Classes for the SM4 block cipher.

SM4 is a block cipher designed by Xiaoyun Wang, et al. The block cipher is part of the Chinese State Cryptography Administration portfolio. The cipher was formely known as SMS4.

SM4 encryption is accelerated on machines with AES-NI. Decryption is not acclerated because it is not profitable. Thanks to Markku-Juhani Olavi Saarinen for help and the code.
