WebFeb 4, 2024 · 10. Written by Douglas Crawford. AES is a symmetric key encryption cipher, and it is generally regarded as the "gold standard” for encrypting data . AES is NIST-certified and is used by the US government for protecting "secure” data, which has led to a more general adoption of AES as the standard symmetric key cipher of choice by just about ... WebNov 14, 2024 · AES data encryption is a more mathematically efficient and elegant cryptographic algorithm, but its main strength rests in the option for various key lengths. AES allows you to choose a 128-bit, 192-bit or 256-bit key, making it exponentially stronger than the 56-bit key of DES. nova scotia halifax waterfront boardwalk
