Free ssl 13 software for linux

yaSSL is an SSL Library for programmers building security functionality into their applications and devices.
yaSSL has a dual licensing model, like MySQL, so it is available under GPL and commercial licenses. Support and consulting are also available for yaSSL.
Main features:
- SSL version 3 and TLS version 1 (client and server)
- OpenSSL compatibility layer
- MySQL integration
- Initial stunnel integration
- MD2, MD5, SHA-1, RIPEMD, HMAC, DES, 3DES, AES, ARC4, TWOFISH, BLOWFISH, RSA, DSS, DH, and PKCS#5 PBKDF2
- Simple API
- Interchangeable crypto and certificate libraries
- PEM and DER certificate support
- Very fast
- Multiple OS support: Win32, Linux, Solaris, FreeBSD, NetBSD, OpenBSD, and Mac OS X
Enhancements:
- This release of contains bugfixes and adds SHA-256, SHA-512, SHA-224, and SHA-384.

sslredir is a simple utility used for redirecting incoming non-SSL connections to outgoing SSL connections.

sslredir project is useful for enabling applications such as mail, news, or IRC clients, which do not support SSL, to connect to SSL servers. It also supports connecting to the remote host through a SOCKS4A proxy, so sslredir is ideal for use with Tor.

sslredir is similar to stunnel or socat, except that it is not as general-purpose as socat. It uses less than 450 lines of Python, so it is simple to audit (although it does rely on M2Crypto which relies on OpenSSL, both of which are rather more difficult to audit). sslredir is also designed to work nicely with Tor, whereas I had run into bugs with both socat and stunnel.

ssl-cert-check is a Bourne shell script that checks the expiration status of digital certificates on SSL servers.
It supports both interactive and batch modes and easily integrates with cron. It provides custom expiration thresholds and can be configured to send email if a certificate is close to expiring.
Enhancements:
- This release contains a new "-i" option to print the certificate issuer.
- The requirement to use GNU date has been removed (the program now uses a built-in Julian date routine).
- The documentation has also been significantly updated to include numerous useful examples.

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.

- An authentication scheme should be allowed to be primary if a secondary scheme also exists.
- Redirection when canceling out of selecting an authentication scheme at logon is incorrect.
Installer
- Stepping back through the installer and changing the certificate type causes unusual behaviour during installation.
- Installation of extensions step in installer is irrelevant.
- Insallation progress bar added.

SCMS project is a secure content management system. Some of its features are a role-based object-oriented design, conformance to XHTML 1.0 Transitional, strict I/O (input/output) validation, a custom session implementation, support for SSL and cookies (when run over SSL), session identifier regeneration, idle session expiration, account locking, account unlocking methods, encryption (with MD5, AES, SHA1, SHA256, SHA512, or WHIRLPOOL), and event logging.
Enhancements:
- The new permission system in users.php was implemented.
- The SCMS DB creation SQL was rewritten to include referential integrity for updates and deletes.

myqslBind manages multiple DNS/BIND (8 and 9) name servers. mysqlBind automates updates to multiple DNS servers, centralizes and stores all zone and resource records for sets of related name servers (ns0...nsN.yourisp.net), and even manages different name server sets from a single browser-based interface.
Unlimited master and slave name servers update their zone information via a job queue system that uses MySQL socket connections. Advanced operations can use mySQL replication clusters for high availability and redundancy.
Large ISPs and other organizations should note that they can easily add SQL functions to customize the program for their special needs.
It supports authentication via SSL Unix password login, SSL personal certificate, or IP-based access with multiple permission levels and individual record ownership.
It is also compatible with mysqlISP.
Enhancements:
- This release has changed to new RAD3 templates.
- These are for a new clean look with a two step action confirmation tab-based interface.
- Many bugs have been fixed.
- Errors in tool-tip documentation, most regarding SOA TTL explanations, have been fixed.
