Block ciphers : work on plaintext of limited size = block. output ciphertexts of same size. David Froot. Protecting data By encryption . How do we transmit information and data, especially over the internet, in a way that is secure and unreadable by anyone but the sender and recipient?. Encryption is simply the process of transforming information, such as plain text or numbers, using an algorithm. Only those with the algorithm can decipher the encrypted information, and even a relatively simple encryption technique can be difficult to decode without the key. . Rainbows (a.k.a. Spectrums).
