WebNov 29, 2016 · A cryptographic key is data that is used to lock or unlock cryptographic functions such as encryption, authentication and authorization. Keys are typically designed to be both random and reasonably long such that they are difficult to guess. The following are common types of cryptographic key. WebThe most common keys are those used for data encryption; however, other types of keys exist for different purposes. A data encryption algorithm uses a (secret) key to convert a message into a ciphertext — that is, a scrambled, unreadable version of the message. One can recover the original message from the ciphertext by using a decryption key.
