This article is about algorithms for encryption and decryption. For an overview of cryptographic technology in general, see Cryptography. In cryptography, encryption is the process of encoding messages or information in such a way that only authorized parties can read it. Encryption does not of itself prevent interception, but denies the message content to the interceptor.
In computer cryptography, a key is a long sequence of bits used by encryption and decryption algorithms. An encryption algorithm takes the original un-encrypted message, and a key like the above, and alters the original message mathematically based on the key's bits to create a new encrypted message.
