"WitrynaUse of IVs in block ciphers and stream ciphers. A block cipher is a way to encrypt data in blocks simultaneously to produce ciphertext. In contrast, a stream cipher encrypts and decrypts data one bit at a time. Both stream and block ciphers use a symmetric key and algorithm for data encryption. IVs are implemented differently in both types of ... " - Importance of ciphers
