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.
