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
This function allows to authenticate a session with a public key read
from memory. It's only supported when libssh2 is backed by OpenSSL.
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 a PEM encoded private key file
stored in memory.
RETURN VALUE
Return 0 on success or negative on failure. It returns LIB‐
SSH2_ERROR_EAGAIN when it would otherwise block. While LIB‐
SSH2_ERROR_EAGAIN is a negative number, it isn't really a failure per
se.
