Web16 mrt. 2024 · In cryptography, we have two important methods to encrypt messages: symmetric encryption and asymmetric encryption. In the symmetric case, both parties share the same key. We use the same key to encrypt and decrypt a message. 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.
