The advantage transposition ciphers have over substitution is they are much harder to decode and have a higher probability of staying encoded from your enemy and even the intended recipient. Substitution on the other hand is easy to create but also means it could be easier to decipher. 2. WebCryptography is a continually evolving field that drives research and innovation.

There are two types of symmetric algorithms (or ciphers): stream and block. A block cipher divides the data into blocks (often 64-bit blocks, but newer algorithms sometimes use 128-bit blocks) and encrypts the data one block at a time.
