Editing Cryptography standards

{{Short description|Number of standards related to cryptography}}
There are a number of '''[[standardization|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 (algorithm)|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 (algorithm)|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* [[Wired Equivalent Privacy]] (WEP), severely flawed and superseded by WPA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 [[Advanced Encryption Standard|AES]] and other improvements on WEP
* [[A5/1]] and [[A5/2]] cell phone encryption for [[GSM]]
