WebJun 6, 2024 · 1 Answer. Sorted by: 2. Theoretically as pointed out by @CodesInChaos there is no need to rotate keys as long as they remain secret. Also as @CodesInChaos points out, you need to architect the system for key rotation in the event of key compromise. The best way to do that is to build key rotation into the app and operational tooling, and then ... WebOne of the approved symmetric-key algorithms for encryption/decryption is the AES. AES is a block-cipher algorithm, which operates on blocks of data during encryption/decryption operations. The AES algorithm encrypts and decrypts information in 128-bit blocks while using 128, 196, or 256-bit keys, which are specified within FIPS PUB 197.
