NAME

       libssh2_userauth_publickey_fromfile - authenticate a session with a public key, read from a file

SYNOPSIS

       #include <libssh2.h>

       int libssh2_userauth_publickey_fromfile_ex(LIBSSH2_SESSION *session,
						  const char *username,
						  const char *publickey,
						  const char *privatekey,
						  const char *passphrase);

DESCRIPTION

       session - Session instance as returned by libssh2_session_init_ex(3)

       username - Pointer to user name to authenticate as.

       username_len - Length of username.

       publickey  - Path name of the public key file.  (e.g. /etc/ssh/hostkey.pub). If libssh2 is built against OpenSSL, this option can be set to
       NULL.

       privatekey - Path name of the private key file. (e.g. /etc/ssh/hostkey)

       passphrase - Passphrase to use when decoding privatekey.

       Attempt public key authentication using a PEM encoded private key file stored on disk

RETURN VALUE

       Return 0 on success or negative on failure.  It returns LIBSSH2_ERROR_EAGAIN when it would otherwise block. While LIBSSH2_ERROR_EAGAIN is a
       negative number, it isn't really a failure per se.

ERRORS

       LIBSSH2_ERROR_ALLOC -  An internal memory allocation call failed.

       LIBSSH2_ERROR_SOCKET_SEND - Unable to send data on socket.

       LIBSSH2_ERROR_SOCKET_TIMEOUT -

       LIBSSH2_ERROR_PUBLICKEY_UNVERIFIED - The username/public key combination was invalid.

       LIBSSH2_ERROR_AUTHENTICATION_FAILED - Authentication using the supplied public key was not accepted.

NAME

       libssh2_userauth_password_ex - authenticate a session with username and password

SYNOPSIS

       #include <libssh2.h>
       int libssh2_userauth_password_ex(LIBSSH2_SESSION *session,
			   const char *username,
			   unsigned int username_len,
			   const char *password,
			   unsigned int password_len,
			   LIBSSH2_PASSWD_CHANGEREQ_FUNC((*passwd_change_cb)));

       #define libssh2_userauth_password(session, username, password) 
	libssh2_userauth_password_ex((session), (username), 
				     strlen(username), 
				     (password), strlen(password), NULL)

DESCRIPTION

       session - Session instance as returned by libssh2_session_init_ex(3)

       username - Name of user to attempt plain password authentication for.

       username_len - Length of username parameter.

       password - Password to use for authenticating username.

       password_len - Length of password parameter.

       passwd_change_cb - If the host accepts authentication but requests that the password be changed, this callback will be issued.  If no call-
       back is defined, but server required password change, authentication will fail.

       Attempt basic password authentication. Note that many SSH servers which appear to support ordinary password authentication actually have it
       disabled and use Keyboard Interactive authentication (routed via PAM or another authentication backed) instead.

RETURN VALUE

       Return 0 on success or negative on failure.  It returns LIBSSH2_ERROR_EAGAIN when it would otherwise block. While LIBSSH2_ERROR_EAGAIN is a
       negative number, it isn't really a failure per se.

ERRORS

       Some of the errors this function may return include:

       LIBSSH2_ERROR_ALLOC -  An internal memory allocation call failed.

       LIBSSH2_ERROR_SOCKET_SEND - Unable to send data on socket.

       LIBSSH2_ERROR_PASSWORD_EXPIRED -

       IBSSH2_ERROR_AUTHENTICATION_FAILED - failed, invalid username/password or public/private key.
