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.

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.

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

What’s the difference? Public key cryptography (asymmetric encryption) involves a pair of keys, while private key cryptography (symmetric encryption) uses a single shared key. Understanding the ...
