Instead, use TEA or Blowfish, which are both reasonably fast. Tiny Encryption Algorithm is a very fast and moderately secure cipher produced by David Wheeler and Roger Needham of Cambridge ...

Padding is the process of adding extra data to the plaintext to make it a multiple of the block size of the encryption algorithm. This is necessary for some block cipher algorithms, such as AES ...

Beaufort cipher The Beaufort ... uses a tableau (shown below) and a keyword to encipher the plaintext. The keyword should be repeated in order to make a key that matches the size of the plaintext. The ...

For example: A weak cipher is defined as an encryption/decryption algorithm that uses a key of insufficient length. Using an insufficient length for a key in an encryption/decryption algorithm opens ...
