See Text Below for Licensing Declaration Licensing See Text Below for Licensing Declaration

Stanford University has a U.S. patent pending for the Secure Remote
Password (SRP) authentication and key-exchange system. To encourage widespread use of strong cryptographic authentication technologies, Stanford University is granting royalty-free licenses for SRP when used in its implicit server authenticating mode, such as implementations based on RFC 2945. Details will soon be available at

Stanford University will also offer non-exclusive licenses in a
nondiscriminatory manner for use of SRP in its bi-directional
authenticating mode (SRP-Z) under reasonable terms and conditions.

Please contact me with any questions regarding the licensing of SRP.

Licensing information, comments, notes, or URL for further information

The SRP Authentication and Key Exchange System, as specified in
RFC 2945, is available royalty-free worldwide for commercial and
non-commercial use.

Extended variants of SRP, such as those based on SRP-Z, may require
a license, which Stanford will grant on a non-exclusive basis, under
reasonable and non-discriminatory terms.
