WebMay 1, 2024 · Cryptography, at its most basic, is the science of using codes and ciphers to protect messages. Encryption is encoding messages with the intent of only allowing the intended recipient to understand the meaning of the message. It is a two way function (you need to be able to undo whatever scrambling you’ve done to the message). WebAlgorithms and key sizes have been selected for consistency with applicable federal standards and to ensure adequate cryptographic strength for PIV applications. All cryptographic algorithms employed in this specification provide at least 112 bits of security strength. For detailed guidance on the strength of cryptographic algorithms, see
