Data Encryption Standard and Advanced Encryption Standard sound similar, and both are examples of symmetric block ciphers. That is where the similarities end, however. DES is an outdated method of data encryption, and development on AES began in the late 1990s when DES was deemed inadequate from a cybersecurity standpoint.

When it was initially developed, the DES symmetric-key algorithm was commonly used for data encryption. It was superseded by the more secure AES algorithm when AES became a federal government standard in 2002.

What is DES encryption?

DES is a block cipher, meaning, rather than encrypting one bit at a time, a cryptographic key and algorithm encrypt a block of data concurrently. When using DES, the same private key is used to encrypt and decrypt a message.
