Free ssl software for linux

SSL-Explorer project is the worlds first open-source SSL VPN solution of its kind. This unique remote access solution provides users and businesses alike with a means of securely accessing network resources from outside the network perimeter using only a standard web browser.
SSL-based VPNs have become a hot topic in recent years. The benefits to productivity and the low maintenance overhead that comes with browser-based VPN solutions are something that cannot be overlooked by most businesses, though implementation costs can often be prohibitive.
In contrast to a conventional IPsec-based solution, no client side code needs to be installed on your end users systems. SSL VPNs rely on Javatm based technology and hence require only a standard web browser to operate.
Standard network protocols can be tunnelled through the SSL connection, meaning that email and intranet web/file resources are easily and securely accessible from outside the corporate network.
The use of SSL is highly beneficial in these circumstances since most firewall policies grant access to SSL traffic by default, meaning that no additional configuration is required. Our solution is not a firewall, but it effectively allows you to lock-down your network, leaving just a single port open on your firewall.

Bitgate Server Software Environment aims to build a multi-protocol environment in which server protocol handlers can be eventually loaded and unloaded on the fly using a center console or controller Web page.
Bitgate Server Software Environment aims to have 99.9% uptime, and have high-availability (Java 6) compliance. It is written in Java 5, and relies completely on Javas I/O functionality to provide non-blocking support for both SSL and non-SSL sockets (transparently).
All configuration is done via XML files, as this is easier to maintain. It includes a minimal demonstration HTTP server.
Enhancements:
- Modified HTTP directory listing to be a little more clean on the output of filenames; shows more information about each file in question as well.
- Added "reset" methods to the ClientContext objects so that Keep-Alive requests are now handled properly.
- Implemented 302 redirects and space encodings on filenames.

- HTTPS extensions to Pythons httplib, urllib, and xmlrpclib.
- Unforgeable HMACing AuthCookies for web session management.
- FTP/TLS client and server.
- S/MIME.
- ZServerSSL: A HTTPS server for Zope.
- ZSmime: An S/MIME messenger for Zope.

Configures your application for use within the Department of Defense.
Main features:
- urns on auto-updates
- Imports DoD Root Certificates
- Setup of CAC Reader driver
- Clarifies SSL error when Common Access Card (smartcard) not present (Firefox)

Root certificates can be verified upon install by clicking on the View option. The fingerprints and other information can be verified at https://crl.gds.disa.mil.

curl and libcurl is a tool for transferring files using URL syntax. It supports HTTP, HTTPS, FTP, FTPS, DICT, TELNET, LDAP, FILE, and GOPHER, as well as HTTP-post, HTTP-put, cookies, FTP upload, resumed transfers, passwords, portnumbers, SSL certificates, Kerberos, and proxies.

curl and libcurl is powered by libcurl, the client-side URL transfer library.

There are bindings to libcurl for over 20 languages and environments.
