Cryptography is the practice and study of techniques for secure communication in the presence of third-party adversaries. It involves the use of algorithms and protocols to protect the confidentiality, integrity, and authenticity of messages. DES (Data Encryption Standard): Adopted in the 1970s,

DES (Data Encryption Standard): Adopted in the 1970s, DES uses a 56-bit key. It operates on 64-bit blocks using Feistel network structures. Due to its short key length, DES is now considered insecure against brute-force attacks.
AES (Advanced Encryption Standard): The modern standard, AES uses key sizes of 128, 192, or 256 bits. It is faster and more secure than DES, utilizing substitution-permutation networks rather than Feistel structures.
