Linux Pluggable Authentication Modules (PAM) is a suite of libraries that allow a Linux system administrator to configure methods to authenticate users. It provides a flexible and centralized way to switch authentication methods for secured applications by using configuration files instead of changing application code. [ 1 ]
Encryption and/or sender authentication of e-mail messages (e.g., using OpenPGP or S/MIME); Encryption and/or authentication of documents (e.g., the XML Signature or XML Encryption standards if documents are encoded as XML); Authentication of users to applications (e.g., smart card logon, client authentication with SSL/TLS).
