Questions about using libssh as SFTP client

[Alan Ong <sarcasigan@xxxxxxxxx>]

Hello,

I have another newbie questions. I am creating a sftp client and I
want to use aes128-ctr cipher.
Does it mean I have to code it like this:

int nResult;
ssh_session session;

session = ssh_new();	
nResult = ssh_options_set(session, SSH_OPTIONS_HOST, "localhost");
nResult = ssh_options_set(session, SSH_OPTIONS_PORT, 22);
nResult = ssh_options_set(session, SSH_OPTIONS_CIPHERS_S_C, "aes128-ctr");
nResult = ssh_options_set(session, SSH_OPTIONS_CIPHERS_C_S, "aes128-ctr");'

Is the above code correct?

Another question is, how do i set in the code to use hmac-sha1?

Thank you for your time.
