3.2.17 Is RSA an official standard today?

RSA is part of many official standards worldwide. The ISO (International Standards Organization) 9796 standard lists RSA as a compatible cryptographic algorithm, as does the Consultative Committee in International Telegraphy and Telephony (CCITT) X.509 security standard. RSA is part of the Society for Worldwide Interbank Financial Telecommunications (SWIFT) standard, the French financial industry's ETEBAC 5 standard, and the ANSI X9.31 draft standard for the U.S. banking industry. The Australian key management standard, AS2805.6.5.3, also specifies RSA.

RSA is found in Internet's proposed PEM (Privacy Enhanced Mail) standard (see Question 3.8.7) and the PKCS standard for the software industry (see Question 3.8.9). The OSI Implementors' Workshop (OIW) has issued implementers' agreements referring to PKCS and PEM, which each include RSA.

A number of other standards are currently being developed and will be announced over the next couple of years; many are expected to include RSA as either an endorsed or a recommended system for privacy and/or authentication.
