Basic-auth is a project mainly written in C++ and C, it's free.
Squid Proxy server helper, for basic authentication type.
Current version: 3.0.2.2
A program to give basic authentication based on sqlite database. In particular it is written for Squid Proxy Server.
It parses the configuration file (YAML syntax) and then it opens a sqlite database connection. If everything gone well, it starts waiting for username and passwords on stdin. The expected syntax is: [username][space][password][return]
Configuration file example is in the root directory while there's another directory called "sql" containing the database setup. Remember to edit them according to what you need!
