The ssh library was designed to be used by programmers needing a working SSH

implementation by the mean of a library. The complete control of the client is

made by the programmer. With libssh, you can remotely execute programs, transfer

files, use a secure and transparent tunnel for your remote programs. With its

Secure FTP implementation, you can play with remote files easily, without

third-party programs others than libcrypto (from openssl).
