AES-ECB Encryption … WebA Stream Cipher is used for symmetric key cryptography, or when the same key is used to encrypt and decrypt data. Stream Ciphers encrypt pseudorandom sequences with bits of plaintext in order to generate ciphertext, usually with XOR. A good way to think about Stream Ciphers is to think of them as generating one-time pads from a given state.
