swesven	6155634d3b	Add the SM4 block cipher, also a no-padding option for block ciphers. This adds an implementation of the SM4 block cipher, and operations to encrypt and decrypt using it with CBC,ECB,CFB,OFB,CTR modes. Also, a "no padding" option is added for AES,DES,3DES and SM4 decryption in ECB/CBC modes. This variant does not attempt to validate the last block as being PKCS#7 padded. This is useful, both since other padding schemes exist, and also for decrypting data where the final block is missing.	2021-03-24 00:58:54 +01:00
