WebCipher block chaining (CBC) is a mode of operation for a block cipher-- one in which a sequence of bits are encrypted as a single unit, or block, with a cipher key applied to the … WebNIST has approved 3DES-CBC (Cipher Block Chaining) as mentioned in this paper. In case you want to change your cryptography library check their FIPS 140 validation status. That way you can ensure that best practices are been followed. Crypto++ as suggested by @Kirill seems to have some FIPS validation passed for some algorithms. Share greenway farms conference center https://robina-int.com
