.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_set2(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
