NAME         top

       gnutls_pkcs11_privkey_generate3 - API function

SYNOPSIS         top

       #include <gnutls/pkcs11.h>

       int gnutls_pkcs11_privkey_generate3(const char * url,
       gnutls_pk_algorithm_t pk, unsigned int bits, const char * label,
       const gnutls_datum_t * cid, gnutls_x509_crt_fmt_t fmt,
       gnutls_datum_t * pubkey, unsigned int key_usage, unsigned int
       flags);

ARGUMENTS         top

       const char * url
                   a token URL

       gnutls_pk_algorithm_t pk
                   the public key algorithm

       unsigned int bits
                   the security bits

       const char * label
                   a label

       const gnutls_datum_t * cid
                   The CKA_ID to use for the new object

       gnutls_x509_crt_fmt_t fmt
                   the format of output params. PEM or DER

       gnutls_datum_t * pubkey
                   will hold the public key (may be NULL)

       unsigned int key_usage
                   One of GNUTLS_KEY_*

       unsigned int flags
                   zero or an OR'ed sequence of GNUTLS_PKCS11_OBJ_FLAGs

DESCRIPTION         top

       This function will generate a private key in the specified by the
       url token. The private key will be generate within the token and
       will not be exportable. This function will store the DER-encoded
       public key in the SubjectPublicKeyInfo format in  pubkey . The
       pubkey should be deinitialized using gnutls_free().

       Note that when generating an elliptic curve key, the curve can be
       substituted in the place of the bits parameter using the
       GNUTLS_CURVE_TO_BITS() macro.

       Since 3.6.3 the objects are marked as sensitive by default unless
       GNUTLS_PKCS11_OBJ_FLAG_MARK_NOT_SENSITIVE is specified.

RETURNS         top

       On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative
       error value.

SINCE         top

       3.4.0
