Algorithms for encrypting computer data come in two main varieties: symmetric and asymmetric. Each encryption type has inherent strengths and weaknesses. Symmetric algorithms convert plain-text ...

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

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

DES (Data Encryption Standard): An older symmetric algorithm now largely replaced by AES due to vulnerabilities, DES was a standard for encryption in the 20th century.

It is a symmetric encryption algorithm that uses keys up to 256 bits in length. It is not only fast and secure, but it’s in the public domain, just like its predecessor.
