• 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

• Key (cryptography) — In cryptography, a key is a piece of information (a parameter) that determines the functional output of a cryptographic algorithm or cipher. Without a key, the algorithm would produce no useful result. In encryption, a key specifies the… …   Wikipedia

• Key strengthening — In cryptography, key strengthening or key stretching refer to techniques used to make a possibly weak key, typically a password or passphrase, more secure against a brute force attack by increasing the time it takes to test each possible key.… …   Wikipedia

• Weak key — In cryptography, a weak key is a key which when used with a specific cipher, makes the cipher behave in some undesirable way. Weak keys usually represent a very small fraction of the overall keyspace, which usually means that if one generates a… …   Wikipedia
