WebHow to find a modular inverse. A naive method of finding a modular inverse for A (mod C) is: step 1. Calculate A * B mod C for B values 0 through C-1. step 2. The modular inverse of A mod C is the B value that makes A * B mod C = 1. Note that the term B mod C can only have an integer value 0 through C-1, so testing larger values for B is redundant.

Cryptology is the study of both cryptography, the use of messages concealed by codes or ciphers, and cryptanalysis, or the breaking of coded messages. It is nearly as old as civilization itself, although ciphers and codes prior to the late medieval period in western Europe tended to be extremely simple by today's standards.

WebFixed tables are normally used, as in the Data Encryption Standard (DES), but in some ciphers the tables are generated dynamically from the key (e.g. the Blowfish and the Twofish encryption algorithms). Example [ edit] One good example of a fixed table is the S-box from DES (S 5 ), mapping 6-bit input into a 4-bit output: WebIn cryptography, an S-box (substitution-box) is a basic component of symmetric key algorithms which performs substitution.
