encryption
In Cryptography law, cryptography, encryption (more specifically, Code, encoding) is the process of transforming information in a way that, ideally, only authorized parties can decode. This process converts the original representation of the inf ...

key generation
Key generation is the process of generating keys in cryptography. A key is used to encrypt and decrypt whatever data is being encrypted/decrypted.
A device or program used to generate keys is called a key generator or keygen.

key agreement
In cryptography, a key-agreement protocol is a protocol whereby two (or more) parties generate a cryptographic Key (cryptography), key as a function of information provided by each honest party so that no party can predetermine the resulting value ...
