Re[2]: passing passphrase as parameter?

[alex rosky <alex22sky@xxxxxxx>]

Well I was not thinking about writing these passwords in the program itself but storing them somewhere on the disk, encrypted, simply as an extra protection. I've been studying the code for hours and it looks that I have to set a callback by using ssh_set_callbacks function, and I tried it but still prompts for passwords. pseudocode:

port = 5555;
hsession= ssh_new();
hbind= ssh_bind_new();
ssh_bind_options_set(hbind, SSH_BIND_OPTIONS_BINDPORT, &port);
ssh_bind_options_set(hbind, SSH_BIND_OPTIONS_DSAKEY, "ssh_host_dsa_key");
ssh_bind_options_set(hbind, SSH_BIND_OPTIONS_RSAKEY, "ssh_host_rsa_key");

memset(&cb, 0, sizeof(cb));
ssh_callbacks_init(&cb);
cb.auth_function = custom_auth;
ssh_set_callbacks(hbind, &cb);

ssh_bind_listen(hbind);

btw, I'm using 0.7.2.
