About:
Libident is a lightweight C library that implements the Ident protocol (RFC 1413), allowing server applications to determine the user identity associated with a TCP connection. It provides a simple API for querying Ident servers, making it valuable for applications requiring user accountability or logging. The library is designed for integration into daemons and services where network identity verification is needed.

Key Features:

RFC 1413 compliant implementation
Lightweight C library suitable for embedded systems
Simple API for easy integration
Supports both synchronous and asynchronous queries
Minimal dependencies

Use Cases:

Adding user identification to IRC daemons and chat servers
Network monitoring and logging systems requiring user accountability
Mail servers verifying connecting users
Custom services needing TCP connection identity verification

Alternatives:

OpenSSL – Provides general network security but includes Ident client functionality as part of its library suite
Custom implementation – Writing RFC 1413 client code from scratch is an alternative but requires protocol expertise and maintenance
