.SH NAME
gnutls_privkey_import_ext3 \- API function
.SH SYNOPSIS
.B #include <gnutls/abstract.h>
.sp
.BI "int gnutls_privkey_import_ext3(gnutls_privkey_t " pkey ", void * " userdata ", gnutls_privkey_sign_func " sign_fn ", gnutls_privkey_decrypt_func " decrypt_fn ", gnutls_privkey_deinit_func " deinit_fn ", gnutls_privkey_info_func " info_fn ", unsigned int " flags ");"
.SH ARGUMENTS
.IP "gnutls_privkey_t pkey" 12
The private key
.IP "void * userdata" 12
private data to be provided to the callbacks
.IP "gnutls_privkey_sign_func sign_fn" 12
callback for signature operations
.IP "gnutls_privkey_decrypt_func decrypt_fn" 12
callback for decryption operations
.IP "gnutls_privkey_deinit_func deinit_fn" 12
a deinitialization function
.IP "gnutls_privkey_info_func info_fn" 12
returns info about the public key algorithm (should not be \fBNULL\fP)
.IP "unsigned int flags" 12
Flags for the import
.SH "DESCRIPTION"
This function will associate the given callbacks with the
\fBgnutls_privkey_t\fP type. At least one of the two callbacks
must be non\-null. If a deinitialization function is provided
then flags is assumed to contain \fBGNUTLS_PRIVKEY_IMPORT_AUTO_RELEASE\fP.

Note that the signing function is supposed to "raw" sign data, i.e.,
without any hashing or preprocessing. In case of RSA the DigestInfo
will be provided, and the signing function is expected to do the PKCS \fB1\fP
1.5 padding and the exponentiation.

The  \fIinfo_fn\fP must provide information on the algorithms supported by
this private key, and should support the flags \fBGNUTLS_PRIVKEY_INFO_PK_ALGO\fP and
\fBGNUTLS_PRIVKEY_INFO_SIGN_ALGO\fP. It must return \-1 on unknown flags.
.SH "RETURNS"
On success, \fBGNUTLS_E_SUCCESS\fP (0) is returned, otherwise a
negative error value.
.SH "SINCE"
3.4.0
.SH "REPORTING BUGS"
