Stunnel 5.59

Stunnel is developed to act like the wrapped SSL encryption between the remote client and a remote server or a remote server. It can be used to add SSL a wide range of possibilities for the internet service is mainly used as the server, POP2, POP3 and IMAP without modifying the code of the program. Stunnel use the OpenSSL library for cryptography, so it supports all encryption algorithms are assembled into the library.

Stunnel - SSL encryption easy to use

The characteristics of the software Stunnel

Mobility (threaded Model):

• - PTHREAD (Posix)
• - FORK (Unix tradition)
• - UCONTEXT (userlevel)
• - WIN32

Performance and scalability:

• - Load sharing between multiple backend servers
• - Buffer the external (to the cluster)
• - Compression (for narrow bandwidth)

Support for the security features of OpenSSL:

• - Access control with TLS-PSK and certificate
• - Remove the certificate CRL and OCSP
• - Support SNI (specify the name of the server) for virtual host based on name
• - PFS (security forwarding perfect) with
• lock mode DH or ECDH
• - Tools, OpenSSL, including CAPI (Microsoft CryptoAPI)

Features multi-platform other:

• - Remote method (socket) and local (type-inetd)
• - Load balance the remote targets with the strategy circle and priority
• - Navigation connect the SSL client when the verify failed
• - IPv6 support
