The 32 bits of the R 0 block are expanded to 48 bits thanks to a table called an expansion table denoted E , in which the 48 bits are mixed together and 16 of them are duplicated:. The algorithm below shows how to obtain, from a bit key made of any 64 alphanumeric characters , 8 different bit keys each used in the DES algorithm:. Cara M enginputkan M atrik.
