WebAug 26, 2024 · Encryption process in CBC mode is performed as C 1 = E n c k ( P 1 ⊕ I V) C i = E n c k ( P i ⊕ C i − 1), 1 < i ≤ n b, where n b is the number of blocks. CBC is designed for chaining, therefore while encryption, if there is one block error at position i, it will affect the rest of ciphertext. WebSpecifying TLS ciphers for etcd and Kubernetes.
