should contain a gnutls_x509_crq_t structure
holds a private key
The message digest to use, GNUTLS_DIG_SHA1 is the safe choice unless you know what you're doing.
unsigned int flags
must be 0
This function will sign the certificate request with a private key.
This must be the same key as the one used in
gnutls_x509_crt_set_key() since a certificate request is self
This must be the last step in a certificate request generation
since all the previously set parameters are now signed.
GNUTLS_E_SUCCESS on success, otherwise an error.
GNUTLS_E_ASN1_VALUE_NOT_FOUND is returned if you didn't set all
information in the certificate request (e.g., the version using
