Quizplus · Accepted Answer

AES (Advanced Encryption Standard) is the symmetric cipher that was approved by the NIST in late 2000 as a replacement for DES. It is currently the most widely used symmetric encryption algorithm and is considered secure for protecting sensitive data. 3DES and Twofish are also symmetric ciphers, but AES is considered to be more secure and efficient. RSA is an asymmetric encryption algorithm, which is used for key exchange and digital signatures, but not for data encryption.
