IDEA (International Data Encryption Algorithm)

Developed in Switzerland and licensed for non-commercial use in PGP. IDEA uses a 128 bit user supplied key to perform a series of nonlinear mathematical transformations on a 64 bit data block. Compare the length of this key with the 56 bits in DES or the 80 bits in Clipper.
