WebWhat is cryptography? Definition Cryptography provides for secure communication in the presence of malicious third-parties—known as adversaries. Encryption uses an algorithm and a key to transform an input (i.e., plaintext) into an encrypted output (i.e., ciphertext). WebWhat is a cryptographic key? In cryptography, it is common to talk about keys (usually a short piece of data) to refer to special inputs of a cryptographic algorithm. The most common keys are those used for data encryption; however, other types of keys exist for different purposes.
