csrp
|

====
|
||||
Tom Cocagne <tom.cocagne@gmail.com>
|
||||
|
||||
csrp is a minimal C implementation of the [Secure Remote Password
|
||||
protocol](http://srp.stanford.edu/). The project consists of a single
|
||||
C file and is intended for direct inclusion into utilizing programs.
|
||||
It's only dependency is OpenSSL.
|
||||
|
||||
*NOTE* This SRP implementation was created before the hashing algoritim specified
|
||||
in RFC 5054 became the de-facto standard for interoperable SRP implementations.
|
||||
The rfc5054_compat branch of this repository uses the RFC 5054 hashing algorithms
|
||||
and is known to be compatible with other SRP implementations. If this version works
|
||||
for you, please consider submitting a patch to this library that implements both the
|
||||
original default and the RFC 5054 implementation to allow a single mainline version
|
||||
of this library going forward.
|
||||
|
||||
|
||||
SRP Overview
|
||||
------------
|
||||
|
||||
SRP is a cryptographically strong authentication
|
||||
protocol for password-based, mutual authentication over an insecure
|
||||
network connection.
|
||||
|
||||
Unlike other common challenge-response autentication protocols, such
|
||||
as Kerberos and SSL, SRP does not rely on an external infrastructure
|
||||
of trusted key servers or certificate management. Instead, SRP server
|
||||
applications use verification keys derived from each user's password
|
||||
to determine the authenticity of a network connection.
|
||||
|
||||
SRP provides mutual-authentication in that successful authentication
|
||||
requires both sides of the connection to have knowledge of the
|
||||
user's password. If the client side lacks the user's password or the
|
||||
server side lacks the proper verification key, the authentication will
|
||||
fail.
|
||||
|
||||
Unlike SSL, SRP does not directly encrypt all data flowing through
|
||||
the authenticated connection. However, successful authentication does
|
||||
result in a cryptographically strong shared key that can be used
|
||||
for symmetric-key encryption.
|
||||
|
||||
This library serves as the basis for a compatible Python module called
|
||||
[pysrp](https://github.com/cocagne/pysrp). The
|
||||
[pysrp](https://github.com/cocagne/pysrp) project contains complete,
|
||||
user-friendly API documentation as well as a comprehensive overview of the SRP
|
||||
protocol. As the APIs are virtually identical, the [pysrp
|
||||
documentation](http://pythonhosted.org/srp/) is an excellent reference for
|
||||
understanding this library.

* Protocol version 6a as described by
|
||||
* http://srp.stanford.edu/design.html
|
||||
*
|
||||
* Author: tom.cocagne@gmail.com (Tom Cocagne)
|
||||
*
|
||||
* Dependencies: OpenSSL (and Advapi32.lib on Windows)
|
||||
*
|
||||
* Usage: Refer to test_srp.c for a demonstration
|
||||
*
|
||||
* Notes:
|
||||
* This library allows multiple combinations of hashing algorithms and
|
||||
* prime number constants. For authentication to succeed, the hash and
|
||||
* prime number constants must match between
|
||||
* srp_create_salted_verification_key(), srp_user_new(),
|
||||
* and srp_verifier_new(). A recommended approach is to determine the
|
||||
* desired level of security for an application and globally define the
|
||||
* hash and prime number constants to the predetermined values.
|
||||
*
|
||||
* As one might suspect, more bits means more security. As one might also
|
||||
* suspect, more bits also means more processing time. The test_srp.c
|
||||
* program can be easily modified to profile various combinations of
|
||||
* hash & prime number pairings.
