The '''S'''ecure '''S'''ocket '''L'''ayer is a way of doing secure communications without application programmers having to actually understand a lot about how cryptosystems work, which is good because implementing a truly secure crypto-engine is (by all reports) really hard indeed. Secure communication is also the purpose of [SSH], but that has its own encryption and authentication mechanisms, quite separate from those of SSL. The main Tcl package used to provide SSL support is [TLS]. [APN] [TWAPI] (as of V4.0b40) has the `tls_socket` command as a drop-in replacement for [socket] on Windows that supports SSL/TLS. Layered on CryptoAPI, it integrates with the certificate store on Windows. ---- [[...]] [AOLserver], [TclSOAP], [HTTPS], [channel implementations], ...

It is a thin layer over Eric Young's free SSLeay. Be sure to carefully research the import and export restrictions of your country before fetching and building this package. It requires Tcl 8 and either SSLeay-0.6.6 or SSleay-0.8.1.

SSL capability is added to the socket with a -ssl option.
