A comprehensive list of standards related to cryptography, including encryption, hash, digital signature, public-key infrastructure, wireless, and government standards. Each standard is briefly described and linked to its source or reference.
AES is a symmetric-key algorithm for encrypting electronic data, established by NIST in 2001. It is a variant of Rijndael, a family of ciphers with different key and block sizes, and has been adopted by the U.S. government and other standards.
DES is a symmetric-key algorithm for encrypting digital data, developed in the 1970s and adopted as a US standard. It has been superseded by AES and is insecure due to its short key length and cryptanalysis.
