csrp | Minimal C implementation of the Secure Remote Password | Authentication library

csrp is a C library typically used in Security, Authentication applications. csrp has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

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] The [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] is an excellent reference for understanding this library.
