Intermodal transport (or intermodal transportation) involves the use of more than one mode of transport for a journey. See: Intermodal passenger transport; Intermodal freight transport
Encryption algorithms At the heart of every encrypted application is the algorithm, the math that scrambles and unscrambles data. In a nutshell, an encryption algorithm is a function which takes a string of data bytes and returns a new dataset containing unintelligible content. The same algorithm is used to decrypt data, which means encrypted data goes in from one side and the original data comes out the other.
Encryption. Traditionally, ciphers have used information contained in secret decoding keys to code and decode messages. The process of coding plaintext to create ciphertext is called encryption and the process of decoding ciphertext to produce the plaintext is called decryption. Modern systems of electronic cryptography use digital keys (bit strings) and mathematical algorithms (encryption algorithms) to encrypt and decrypt information.
