NAME
gnutls_certificate_set_rawpk_key_mem - API function
SYNOPSIS
#include <gnutls/gnutls.h>
int gnutls_certificate_set_rawpk_key_mem(gnutls_certificate_credentials_t cred, const gnutls_datum_t *
spki, const gnutls_datum_t * pkey, gnutls_x509_crt_fmt_t format, const char * pass, unsigned int
key_usage, const char ** names, unsigned int names_length, unsigned int flags);
ARGUMENTS
gnutls_certificate_credentials_t cred
is a gnutls_certificate_credentials_t type.
const gnutls_datum_t * spki
contains a raw public key in PKIX.SubjectPublicKeyInfo format.
const gnutls_datum_t * pkey
contains a raw private key.
gnutls_x509_crt_fmt_t format
encoding of the keys. DER or PEM.
const char * pass
an optional password to unlock the private key pkey.
unsigned int key_usage
An ORed sequence of GNUTLS_KEY_* flags.
const char ** names
is an array of DNS names belonging to the public-key (NULL if none).
unsigned int names_length
holds the length of the names list.
unsigned int flags
an ORed sequence of gnutls_pkcs_encrypt_flags_t. These apply to the private key pkey.
DESCRIPTION
This function sets a public/private keypair in the gnutls_certificate_credentials_t type to be used for
authentication and/or encryption. spki and privkey should match otherwise set signatures cannot be
validated. In case of no match this function returns GNUTLS_E_CERTIFICATE_KEY_MISMATCH. This function
should be called once for the client because there is currently no mechanism to determine which raw
public-key to select for the peer when there are multiple present. Multiple raw public keys for the
server can be distinghuished by setting the names .
Note here that spki is a raw public-key as defined in RFC7250. It means that there is no surrounding
certificate that holds the public key and that there is therefore no direct mechanism to prove the
authenticity of this key. The keypair can be used during a TLS handshake but its authenticity should be
established via a different mechanism (e.g. TOFU or known fingerprint).
The supported formats are basic unencrypted key, PKCS8, PKCS12, and the openssl format and will be
autodetected.
If the raw public-key and the private key are given in PEM encoding then the strings that hold their
values must be null terminated.
Key usage (as defined by X.509 extension (2.5.29.15)) can be explicitly set because there is no
certificate structure around the key to define this value. See for more info
gnutls_x509_crt_get_key_usage().
Note that, this function by default returns zero on success and a negative value on error. Since 3.5.6,
when the flag GNUTLS_CERTIFICATE_API_V2 is set using gnutls_certificate_set_flags() it returns an index
(greater or equal to zero). That index can be used in other functions to refer to the added key-pair.
RETURNS
On success, GNUTLS_E_SUCCESS (0) is returned, in case the key pair does not match
GNUTLS_E_CERTIFICATE_KEY_MISMATCH is returned, in other erroneous cases a different negative error code
is returned.
SINCE
3.6.6
