.TH libssh2_agent_sign 3 "1 Oct 2022" "libssh2" "libssh2" .SH NAME libssh2_agent_sign - sign data, with the help of ssh-agent .SH SYNOPSIS .nf #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); .fi .SH DESCRIPTION \fIagent\fP - ssh-agent handle as returned by .BR libssh2_agent_init(3) \fIidentity\fP - Public key to authenticate with, as returned by .BR libssh2_agent_get_identity(3) \fIsig\fP - A pointer to a buffer in which to place the signature. The caller is responsible for freeing the signature with LIBSSH2_FREE. \fIs_len\fP - A pointer to the length of the sig parameter. \fIdata\fP - The data to sign. \fId_len\fP - The length of the data parameter. \fImethod\fP - A buffer indicating the signing method. This should match the string at the start of identity->blob. \fImethod_len\fP - 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_set(3) using LIBSSH2_CALLBACK_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. .SH RETURN VALUE Returns 0 if succeeded, or a negative value for error. .SH AVAILABILITY Added in libssh2 1.11.0 .SH SEE ALSO .BR libssh2_agent_init(3) .BR libssh2_agent_get_identity(3) .BR libssh2_agent_userauth(3) .BR libssh2_session_callback_set(3)
