Kerberos
Kerberos is a network authentication system developed by Project Athena at MIT. It uses secret keys for both encryption and authentication. It does not provide digital signatures: its purpose is to authenticate requests for network resources rather than t ...
Key
In cryptography, a key is a large number used (in conjunction with a cryptographic algorithm) to lock plaintext into ciphertext, and unlock ciphertext into plaintext.
Key Distribution
One of the biggest practical problems in symmetric cryptography (and perhaps the driving force behind the development of asymmetric public key cryptography) is the secure distribution of keys. There are two elements to the problem: how do you distribute t ...
Key File
Some encryption programs store your encryption keys in a file where they can be conveniently accessed. Usually, the keys are themselves strongly encrypted -- this means that you need to enter a pass-phrase to begin using the key file, but you do not then ...
