libssh is a C library that enables you to write a program that uses the

The SSH protocol is encrypted, ensures data integrity, and provides strong

libssh is a Free Software / Open Source project. The libssh library
is distributed under LGPL license. The libssh project has nothing to do with
"libssh2", which is a completly different and independant project.
libssh can run on top of either libgcrypt (http://directory.fsf.org/project/libgcrypt/)
or libcrypto (http://www.openssl.org/docs/crypto/crypto.html), two general-purpose
This tutorial concentrates for its main part on the "client" side of libssh.
To learn how to accept incoming SSH connexions (how to write a SSH server),
you'll have to jump to the end of this document.
This tutorial describes libssh version 0.5.0. This version is the development
version and is *not* published yet. However, the examples should work with
little changes on versions like 0.4.2 and later.
