WebThe first plaintext block is added XOR to a random initialization vector (commonly referred to as IV). The vector has the same size as a plaintext block. Encryption in CBC mode can only be performed by using one thread. Despite this disadvantage, this is a very popular way of using block ciphers. CBC mode is used in many applications.

"WebNov 14, 2024 · CBC In order to overcome the ECB weakness, CBC mode uses an Initialization Vector (IV) to augment the encryption. First, CBC uses the plaintext block xor with the IV. Then it encrypts the result to the ciphertext block. In the next block, it uses the encryption result to xor with the plaintext block until the last block. " - Blocks cbc
