Questions tagged [libssh]

libssh is a mulitplatform C library implementing the SSHv2 and SSHv1 protocol on client and server side.

libssh is a C library that enables you to write a program that uses the SSH protocol. With it, you can remotely execute programs, transfer files, or use a secure and transparent tunnel for your remote programs. The SSH protocol is encrypted, ensures data integrity, and provides strong means of authenticating both the server and the client. The library hides a lot of technical details from the SSH protocol, but this does not mean that you should not try to know about and understand these details.

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 completely different and independent project.

libssh can run on top of either libgcrypt or libcrypto, two general-purpose cryptographic libraries.
