Encryption protects digital data secretly by converting plaintext to ciphertext. Two common encryption forms are Symmetric and Asymmetric Encryption.

The encryption process generates cryptographic keys that are used to lock (encrypt) and unlock (decrypt) data. There are two forms of encryption keys: symmetric and asymmetric ...

Symmetric encryption: uses an identical private key to encrypt and decrypt data. Examples: AES, DES, 3DES. Vulnerable to Grover's algorithm.
