libssh2_agent_sign(3) libssh2 libssh2_agent_sign(3) NAME libssh2_agent_sign - sign data, with the help of ssh-agent SYNOPSIS #include <libssh2.h> int libssh2_agent_sign(LIBSSH2_AGENT *agent, struct libssh2_agent_publickey *identity, unsigned char **sig, size_t *s_len, const unsigned char *data, size_t d_len, const char *method, unsigned int method_len); DESCRIPTION agent - ssh-agent handle as returned by libssh2_agent_init(3) identity - Public key to authenticate with, as returned by lib- ssh2_agent_get_identity(3) sig - A pointer to a buffer in which to place the signature. The caller is responsible for freeing the signature with LIBSSH2_FREE. s_len - A pointer to the length of the sig parameter. data - The data to sign. d_len - The length of the data parameter. method - A buffer indicating the signing method. This should match the string at the start of identity->blob. method_len - The length of the method parameter. Sign data using an ssh-agent. This function can be used in a callback registered with libssh2_session_callback_set2(3) using LIBSSH2_CALL- BACK_AUTHAGENT_SIGN to sign an authentication challenge from a server. However, the client is responsible for implementing the code that calls this callback in response to a SSH2_AGENTC_SIGN_REQUEST message. RETURN VALUE Returns 0 if succeeded, or a negative value for error.
