gnutls_x509_crq_get_extension_by_oid(3) 			      gnutls				   gnutls_x509_crq_get_extension_by_oid(3)

NAME

       gnutls_x509_crq_get_extension_by_oid - API function

SYNOPSIS

       #include <gnutls/x509.h>

       int  gnutls_x509_crq_get_extension_by_oid(gnutls_x509_crq_t  crq, const char * oid, int indx, void * buf, size_t * buf_size, unsigned int *
       critical);

ARGUMENTS

       gnutls_x509_crq_t crq
		   should contain a gnutls_x509_crq_t structure

       const char * oid
		   holds an Object Identifier in a null terminated string

       int indx    In case multiple same OIDs exist in the extensions, this specifies which to get. Use (0) to get the first one.

       void * buf  a pointer to a structure to hold the name (may be null)

       size_t * buf_size
		   initially holds the size of	buf

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

DESCRIPTION

       This function will return the extension specified by the OID in the certificate.  The extensions  will  be  returned  as  binary  data  DER
       encoded, in the provided buffer.

RETURNS

       On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error code in case of an error.  If the certificate does not contain the
       specified extension GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned.

SINCE

       2.8.0

NAME

       gnutls_x509_crq_get_key_purpose_oid - API function

SYNOPSIS

       #include <gnutls/x509.h>

       int gnutls_x509_crq_get_key_purpose_oid(gnutls_x509_crq_t crq, int indx, void * oid, size_t * sizeof_oid, unsigned int * critical);

ARGUMENTS

       gnutls_x509_crq_t crq
		   should contain a gnutls_x509_crq_t structure

       int indx    This specifies which OID to return, use (0) to get the first one

       void * oid  a pointer to a buffer to hold the OID (may be NULL)

       size_t * sizeof_oid
		   initially holds the size of	oid

       unsigned int * critical
		   output variable with critical flag, may be NULL.

DESCRIPTION

       This  function  will  extract  the  key purpose OIDs of the Certificate specified by the given index.  These are stored in the Extended Key
       Usage extension (2.5.29.37).  See the GNUTLS_KP_* definitions for human readable names.

RETURNS

       GNUTLS_E_SHORT_MEMORY_BUFFER if the provided buffer is not long enough, and in that case the * sizeof_oid will be updated with the required
       size.  On success 0 is returned.
