A block cipher takes a block of plaintext bits and generates a block of ciphertext bits, generally of same size. The size of block is fixed in the given scheme. The choice of block size does not directly affect to the strength of encryption scheme. The strength of cipher depends up on the key length.

Why are ciphers used?

Cryptographic ciphers are used to convert ciphertext to plaintext and back. Symmetric cryptography uses the same key to encrypt and decrypt data, while asymmetric cryptography, also known as public key cryptography, uses public and private keys to encrypt and decrypt data.

Although the pigpen cipher looks unintelligible, it is actually a fairly basic form of the substitution cipher. The letters of the alphabet are written out on 4 grids. To write your code, take the portion of the grid in which the letter you require is written. This then becomes your code!
