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.
II. Symmetric algorithms: As the name suggests, symmetric key algorithms use the same key to encrypt as well as decrypt message. Some of the commonly used symmetric key algorithms are: DES (Data Encryption Standard): DES uses a 56-bit key on each 64-bit chunk of data. It is limited in used due to its short key length.
