Difference between block cipher and stream cipher

Stream cipher algorithm :it must follow XOR. The plain text is encrypted by 1 byte at a time. A stream cipher is a symmetric key cipher. Where a plain text digits are combined with a pseudo random cipher digits stream(key stream), in a stream c...See more

ipher each plain text digit is encrypted 1 at a time with the corresponding digits of the key stream to give digits of the cipher text stream. Block cipher:block cipher operates on large block of digits with a fixed size. It follows XOR logic .block cipher techniques involves encryption of one block of text at a time. Decryption also takes one block of encrypted text at a time.
