libssh2_userau...ckey_frommemory(3) libssh2libssh2_userau...ckey_frommemory(3) 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 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 either a public key file or a PEM encoded private key file stored in memory. When providing a private key, the public key is automatically extracted from it. When providing both, the passed public key takes precedence. RETURN VALUE Return 0 on success or negative on failure. It returns LIBSSH2_ER- ROR_EAGAIN when it would otherwise block. While LIBSSH2_ERROR_EAGAIN is a negative number, it is not 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. AVAILABILITY libssh2_userauth_publickey_frommemory was added in libssh2 1.6.0 Sup- ported with OpenSSL, WinCNG, mbedTLS, OS/400 crypto backends.
