.SH NAME
|
|
libssh2_userauth_publickey_fromfile_ex - authenticate a session with a public key, read from a file
|
|
.SH SYNOPSIS
|
|
.nf
|
|
#include <libssh2.h>
|
|
|
|
int
|
|
libssh2_userauth_publickey_fromfile_ex(LIBSSH2_SESSION *session,
|
|
const char *username,
|
|
unsigned int username_len,
|
|
const char *publickey,
|
|
const char *privatekey,
|
|
const char *passphrase);
|
|
.fi
|
|
.SH DESCRIPTION
|
|
\fIsession\fP - Session instance as returned by
|
|
\fBlibssh2_session_init_ex(3)\fP
|
|
|
|
\fIusername\fP - Pointer to user name to authenticate as.
|
|
|
|
\fIusername_len\fP - Length of \fIusername\fP.
|
|
|
|
\fIpublickey\fP - Path name of the public key file.
|
|
(e.g. /etc/ssh/hostkey.pub). If libssh2 is built against OpenSSL, this option
|
|
can be set to NULL.
|
|
|
|
\fIprivatekey\fP - Path name of the private key file. (e.g. /etc/ssh/hostkey)
|
|
|
|
\fIpassphrase\fP - Passphrase to use when decoding \fIprivatekey\fP.
|
|
|
|
Attempt public key authentication using either a public key file or a PEM
|
|
encoded private key file stored on disk. When providing a private key, the
|
|
public key is automatically extracted from it. When providing both, the
|
|
passed public key takes precedence.
|
|
.SH 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 is not really a failure per se.
|
|
.SH ERRORS
|
|
\fILIBSSH2_ERROR_FILE\fP - An issue opening, reading or parsing the disk file.
|
|
|
|
\fILIBSSH2_ERROR_ALLOC\fP - An internal memory allocation call failed.
|
|
|
|
\fILIBSSH2_ERROR_SOCKET_SEND\fP - Unable to send data on socket.
|
|
|
|
\fILIBSSH2_ERROR_SOCKET_TIMEOUT\fP -
|
|
|
|
\fILIBSSH2_ERROR_PUBLICKEY_UNVERIFIED\fP - The username/public key
|
|
combination was invalid.
|
|
|
|
\fILIBSSH2_ERROR_AUTHENTICATION_FAILED\fP - Authentication using the supplied
|
|
public key was not accepted.
