Detailed Description

Encryption transformation.

Enc provides implementation for encryption transformation. All key sizes are supported.

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

Since
Crypto++ 6.0, AESNI encryption since Crypto++ 8.0
