• 128 (number) — 128 (one hundred [and] twenty eight) is the natural number following 127 and preceding 129. ← 127 129 → 128 ← …   Wikipedia

• Key size — In cryptography, key size or key length is the size measured in bits[1] of the key used in a cryptographic algorithm (such as a cipher). An algorithm s key length is distinct from its cryptographic security, which is a logarithmic measure of the… …   Wikipedia

• Key schedule — In cryptography, the so called product ciphers are a certain kind of ciphers, where the (de )ciphering of data is done in rounds . The general setup of each round is the same, except for some hard coded parameters and a part of the cipher key,… …   Wikipedia
