Sets which ssh backend should be used by default for the integrated ssh client.
Possible values are:
"Ssh2"- use libssh2
"LibSsh"- use libssh
Despite the naming,
libssh2 is not a newer version of
libssh, they are
completely separate ssh implementations.
In prior releases,
"Ssh2" was the only option.
"LibSsh" is the default
as it has broader support for newer keys and cryptography, and has clearer
feedback about authentication events that require entering a passphrase.
