Encryption standards[edit]

·         Data Encryption Standard (DES, now obsolete)

·         Triple-DES

·         Advanced Encryption Standard (AES)

·         RSA the original public key algorithm

·         OpenPGP

·         CipherSaber

Hash standards[edit]

·         MD5 128-bit (obsolescent)

·         SHA-1 160-bit

·         SHA-2 available in 224, 256, 384 and 512-bit variants

·         HMAC keyed hash

·         PBKDF2 Key derivation function (RFC 2898)

Digital signature standards[edit]

·         Digital Signature Standard (DSS), based on the Digital Signature Algorithm (DSA)

·         RSA

Public-key infrastructure (PKI) standards[edit]

·         X.509 Public Key Certificates

Wireless Standards[edit]

·         Wired Equivalent Privacy (WEP), severely flawed and superseded by WPA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
