Cryptography standards
From HandWiki
Short description: Number of standards related to cryptography
There are a number of standards related to cryptography. Standard algorithms and protocols provide a focus for study; standards for popular applications attract a large amount of cryptanalysis.
Encryption standards
- Data Encryption Standard (DES, now obsolete)
- Advanced Encryption Standard (AES)
- RSA the original public key algorithm
- OpenPGP
Hash standards
- MD5 128-bit (obsolete)
- SHA-1 160-bit (obsolete)
- SHA-2 available in 224, 256, 384, and 512-bit variants
- HMAC keyed hash
- PBKDF2 Key derivation function (RFC 2898)
Digital signature standards
- Digital Signature Standard (DSS), based on the Digital Signature Algorithm (DSA)
- RSA
- Elliptic Curve DSA
Public-key infrastructure (PKI) standards
- X.509 Public Key Certificates
Wireless Standards
- Wired Equivalent Privacy (WEP), severely flawed and superseded by WPA
- Wi-Fi Protected Access (WPA) better than WEP, a 'pre-standard' partial version of 802.11i
- 802.11i a.k.a. WPA2, uses AES and other improvements on WEP
- A5/1 and A5/2 cell phone encryption for GSM

- FIPS PUB 181 Automated Password Generator (APG) 1993
- FIPS PUB 185 Escrowed Encryption Standard (EES) 1994, a key escrow system that provides for decryption of telecommunications when lawfully authorized.
- FIPS PUB 186-2 Digital Signature Standard (DSS) 2000
- FIPS PUB 190 Guideline for the Use of Advanced Authentication Technology Alternatives 1994
- FIPS PUB 191 Guideline for the Analysis of local area network Security 1994
