The key imposes a decryption algorithm onto the data. This decryption algorithm reverses the encryption algorithm, returning the data to plaintext. The longer the encryption key is, the more difficult it is to decode. For a 40-bit encryption key, over one trillion possible decryption keys exist...

RSA (Rivest-Shamir-Adleman): RSA is an asymmetric encryption algorithm that is named after its inventors. It relies on the mathematical complexity of prime numbers to generate key pairs. It uses a public-private key pair for encryption and decryption, making it suitable for secure data transmissi...
The other multiplications needed for the AES MixColumns routine in the encryption and decryption algorithm follow the same general pattern, as shown here: Copy b * 0x09 = b * (0x08 + 0x01) = (b * 0x02 * 0x02 * 0x02) + (b * 0x01) b * 0x0b = b * (0x08 + 0x02 + 0x01...
Since we have recovered our original text back, it’s a sign our encryption-decryption algorithm using a lookup table is works well! Let’s now see if we canextend the character setto include not just lowercase/uppercase characters but also digits and punctuations. ...
