gnutls_x509_crq_get_basic_constraints(3)			      gnutls				  gnutls_x509_crq_get_basic_constraints(3)

NAME

       gnutls_x509_crq_get_basic_constraints - get certificate's basic constraints

SYNOPSIS

       #include <gnutls/x509.h>

       int gnutls_x509_crq_get_basic_constraints(gnutls_x509_crq_t cert, unsigned int * critical, int * ca, int * pathlen);

ARGUMENTS

       gnutls_x509_crq_t cert
		   should contain a gnutls_x509_crq_t structure

       unsigned int * critical
		   will be non zero if the extension is marked as critical

       int * ca    pointer to output integer indicating CA status, may be NULL, value is 1 if the certificate CA flag is set, 0 otherwise.

       int * pathlen
		   pointer  to output integer indicating path length (may be NULL), non-negative values indicate a present pathLenConstraint field
		   and the actual value, -1 indicate that the field is absent.

DESCRIPTION

       This function will read the certificate's basic constraints, and return the certificates CA status.  It reads  the  basicConstraints  X.509
       extension (2.5.29.19).

RETURN VALUE

       If  the	certificate is a CA a positive value will be returned, or zero if the certificate does not have CA flag set.  A negative value may
       be returned in case of errors.  If the certificate does not contain the	basicConstraints  extension  GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE
       will be returned.

NAME

       gnutls_x509_crq_get_key_usage - API function

SYNOPSIS

       #include <gnutls/x509.h>

       int gnutls_x509_crq_get_key_usage(gnutls_x509_crq_t crq, unsigned int * key_usage, unsigned int * critical);

ARGUMENTS

       gnutls_x509_crq_t crq
		   should contain a gnutls_x509_crq_t structure

       unsigned int * key_usage
		   where the key usage bits will be stored

       unsigned int * critical
		   will be non-zero if the extension is marked as critical

DESCRIPTION

       This function will return certificate's key usage, by reading the keyUsage X.509 extension (2.5.29.15).	The key usage value will ORed val-
       ues  of	 the:	GNUTLS_KEY_DIGITAL_SIGNATURE,	GNUTLS_KEY_NON_REPUDIATION,   GNUTLS_KEY_KEY_ENCIPHERMENT,   GNUTLS_KEY_DATA_ENCIPHERMENT,
       GNUTLS_KEY_KEY_AGREEMENT, GNUTLS_KEY_KEY_CERT_SIGN, GNUTLS_KEY_CRL_SIGN, GNUTLS_KEY_ENCIPHER_ONLY, GNUTLS_KEY_DECIPHER_ONLY.

RETURNS

       the  certificate  key usage, or a negative error code in case of parsing error.	If the certificate does not contain the keyUsage extension
       GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned.
