# ucspi-tools
The **UNIX Client/Server Program Interface Tool Suite** is bunch of tools to
handle UCSPI connections.
## sockc
*sockc* is an ucpi SOCKS client. It handles the socks protocol transparently
and establishes further connection through the corresponding SOCKS server.
*sockc* supports SOCKS version 5.
## httppc
*httppc* is an HTTP proxy client. It handles the HTTP protocol transparently
and establishes a tunnel via the HTTP CONNECT method.
## tlsc
*tlsc* establishes an TLS connection and builds an crypto interface between the
network side and program side of the exec-chain. It depends on libtls from
LibreSSL.
## tlss
*tlss* accepts server side tls connections. It also uses libtls for encryption.
## sslc
*sslc* is a legacy version of tlsc which just depends on plain old OpenSSL. It
just contains rudiment certificate checks.
## httpc
The HTTP client is just a stub for testing. It needs to be rewritten for
productive use.
## examples
Just open a tcp connection to google.de and make a fetch of the start page.
```shell
tcpclient www.google.de 80 http www.google.de
```
Get the google index page over a local socks proxy:
```shell
tcpclient 127.0.0.1 8080 socks www.google.de 80 ./http.sh www.google.de
```
If you have to use a socks proxy you could always use socks with the following
alias:
```shellscript
alias tcpclient="tcpclient 127.0.0.1 8080 socks"
tcpclient www.google.de 80
```
