NAME

       libssh2_userauth_publickey_frommemory  -  authenticate  a  session with a public key, read
       from memory

SYNOPSIS

       #include <libssh2.h>

       int libssh2_userauth_publickey_frommemory(LIBSSH2_SESSION *session,
                                                  const char *username,
                                                  size_t username_len,
                                                  const char *publickeydata,
                                                  size_t publickeydata_len,
                                                  const char *privatekeydata,
                                                  size_t privatekeydata_len,
                                                  const char *passphrase);

DESCRIPTION

       This function allows to authenticate a session with a public key read from  memory.   It's
       only  supported when libssh2 is backed by OpenSSL.  session - Session instance as returned
       by libssh2_session_init_ex(3)

       username - Remote user name to authenticate as.

       username_len - Length of username.

       publickeydata - Buffer containing the contents of a public key file.

       publickeydata_len - Length of public key data.

       privatekeydata - Buffer containing the contents of a private key file.

       privatekeydata_len - Length of private key data.

       passphrase - Passphrase to use when decoding private key file.

       Attempt public key authentication using a PEM encoded private key file stored in memory.

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.

AVAILABILITY

       libssh2_userauth_publickey_frommemory was added in libssh2 1.6.0
