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,
                                                  unsigned int ousername_len,
                                                  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  LIB-
       SSH2_ERROR_EAGAIN  when  it   would   otherwise   block.   While   LIB-
       SSH2_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  combina-
       tion was invalid.

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