Non-stop authentication with Linux clusters
This documentation discusses how IBM uses an LDAP (Lightweight Directory Access Protocol) server to provide authentication services to which various applications can subscribe. It also discusses how they use the heartbeat package from the Linux-HA in
The GNU Transport Layer Security Library
GnuTLS is a project that aims to develop a library which provides a secure layer, over a reliable transport layer (ie. TCP/IP).
Policies, Procedures, and PKI
Excerpted from Planning for PKI: Best Practices Guide for Deploying Public Key Infrastructure by Russ Housley and Tim Polk. John Wiley & Sons 2001.
Linux VPN Masquerade
VPN Masquerade is the part of IP Masquerade which enables you to use IPsec-based and PPTP-based Virtual Private Network clients from behind a shared-access firewall.
Stegdetect
Stegdetect is an automated tool for detecting steganographic content in images. It is capable of detecting severval different steganographic methods to embed hidden information in JPEG images.
Secure Communication with GnuPG on Linux
This document discusses GnuPG, which is a tool for secure communication and data storage. It can be used to encrypt data and to create digital signatures. GnuPG is a complete and free replacement for PGP.
Conventional Public Key Infrastructure
This is a great document that explains public key infrastructure, X.509 and certificates, and the problems with existing methods.
Clear Text Communication - Slaying the Beast
In this document, several aspects of implementing a secure shell system with OpenSSH are discussed.
Encryption and Security-related Resources
Probably the most comprehensive list of crypto and security-related resources on the web. If you need it, it's here.
AES Report
This document describes the AES and Rijndael in great detail, including the selection process and technical details.
SSL and Certificates
The Secure Sockets Layer protocol provides one means for achieving these goals and is the subject of this article. This document introduces SSL by reviewing cryptographic techniques and by discussing certificates. It also describes SSL and packages f
mod_ssl
This module provides strong cryptography for the Apache 1.3 webserver via the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols by the help of the Open Source SSL/TLS toolkit OpenSSL, which is based on SSLeay from Eric
tinc VPN daemon
tinc is a Virtual Private Network (VPN) daemon that uses tunneling and encryption to create a secure private network between hosts on the Internet. Because the tunnel appears to the IP level network code as a normal network device, there is no need t
Commercial PGP
This is the commercial version of the Pretty Good Privacy package. PGP can be used to encrypt email documents and normal files using strong cryptography.
Dante proxy/firewall
Dante is a circuit-level firewall/proxy that can be used to provide convenient and secure network connectivity to a wide range of hosts while requiring only the server Dante runs on to have external network connectivity.
CIPE - Crypto IP Encapsulation
This is an ongoing project to build encrypting IP routers. The protocol used is as lightweight as possible. It is designed for passing encrypted packets between prearranged routers in the form of UDP packets. This is not as flexible as IPSEC but it i
OpenSSL Project
The OpenSSL Project is a collaborative effort to develop a robust, commercial-grade, full-featured, and Open Source toolkit implementing the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols as well as a full-strength g
The GNU Privacy Guard
GnuPG is a complete and free replacement for PGP. Because it does not use IDEA or RSA it can be used without any restrictions. GnuPG is a RFC2440 (OpenPGP) compliant application.
