This paper proposes a high-throughput implementation of AES (Advanced Encryption Standard) supporting encryption and decryption with 128-bit cipher key.

Researchers at Fox-IT have developed a technique for cracking AES-256 encryption without the key and from up to a meter away.

Marriot revealed in a court case around a massive 2018 data breach that it had been using secure hash algorithm 1 and not the much more secure AES-1 encryption as it had earlier maintained.

About AES-256 Bit Encryption The technique of concealing plaintext data using the AES algorithm and a 256-bit AES key length is known as 256-bit AES encryption.
