Authen::Simple::WebForm is a Perl library for simple authentication against existing Web based forms using the Authen::Simple framework. This wraps up the LWP (libwww-perl) calls needed to attempt a login to a site that uses an HTML form for logins. It supports logins that require cookies, various form variables, special headers, multi-stage logins, and more.
sec-wall is a feature-packed security proxy that supports SSL/TLS, WS-Security, HTTP Auth Basic/Digest, extensible authentication schemes based on custom HTTP headers and XPath expressions, powerful URL matching/rewriting, and an optional header enrichment. It's a security wall with which you can conveniently fence otherwise defenseless backend servers.
pysrp is a Python module that provides an implementation of the Secure Remote Password protocol (SRP), 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.
The HOTP Toolkit package contains tools that are useful when deploying the one-time password HOTP technology. It contains a shared library, a command-line tool to generate and validate one-time passwords, and a PAM module (pam_hotp) to make system login or SSH use HOTP one-time passwords for authentication.
