About:
Cyrus SASL is an implementation of the Simple Authentication and Security Layer framework. It provides a generic way for applications to add authentication support to their protocols, decoupling the authentication mechanism from the application logic. This allows clients and servers to negotiate various authentication methods, including Kerberos, OTP, and PLAIN, for secure communication.

Key Features:

Supports multiple authentication mechanisms (GSSAPI, PLAIN, LOGIN, CRAM-MD5, etc.)
Decouples application logic from authentication protocols
Provides a plugin architecture for extensibility
Integrates with Kerberos for secure network authentication

Use Cases:

Authenticating SMTP, IMAP, and POP3 connections in mail servers and clients
Securing custom network daemons and services
Implementing single sign-on (SSO) in network applications using Kerberos

Alternatives:

GnuTLS – Focuses on TLS protocol implementation rather than generic SASL authentication.
OpenSSL – Provides cryptographic primitives and TLS, but does not offer a generic SASL framework.
