I understand how a programming library works. By "option" I simply meant is there a way to force libssh2 to only one (or a subset) of the MACs it was compiled to support? I am using the library to do some specific compliance testing.

With the sftp command on Linux I can pass the -oMACs parameter to do this and I am wanting to do the same thing. Thanks.

Build libssh2 with the MACs you want it to use. It negotiates with the server using the algorithms it was built with.

What option? libssh2 is a programming library. It does not have options.
