NAME

CSSM_CL_CertGroupFromVerifiedBundle — Verify the signature of a bundle (CDSA)

SYNOPSIS

# include <cssm.h>
API:
CSSM_RETURN CSSMAPI CSSM_CL_CertGroupFromVerifiedBundle
(CSSM_CL_HANDLE CLHandle,
CSSM_CC_HANDLE CCHandle,
const CSSM_CERT_BUNDLE *CertBundle,
const CSSM_DATA *SignerCert,
CSSM_CERTGROUP_PTR *CertGroup)
SPI:
CSSM_RETURN CSSMCLI CL_CertGroupFromVerifiedBundle
(CSSM_CL_HANDLE CLHandle,
CSSM_CC_HANDLE CCHandle,
const CSSM_CERT_BUNDLE *CertBundle,
const CSSM_DATA *SignerCert,
CSSM_CERTGROUP_PTR *CertGroup)

LIBRARY

Common Security Services Manager library (cdsa$incssm300_shr.exe)

PARAMETERS

CLHandle (input) 

The handle that describes the add-in certificate library module used to perform this function.

CCHandle (input/optional)
  

The handle of the cryptographic context to control the verification operation.

CertBundle (input)
  

A structure containing a reference to a signed, encoded bundle of certificates and to descriptors of the type and encoding of the bundle. The bundled certificates are to be separated into a certificate group (list of individual encoded certificates). If the bundle type and bundle encoding are not specified, the add-in module might either attempt to decode the bundle assuming a default type and encoding or might immediately fail.

SignerCert (input/optional)
  

The certificate to be used to verify the signature on the certificate bundle. If the bundle is signed but this field is not specified, then the module will assume a default certificate for verification.

CertGroup (output)
  

A pointer to the certificate group, represented as an array of individual, encoded certificates. The certificate group and CSSM_CERTGROUP substructures are allocated by the serivce provider and must be deallocated by the application. The group contains all certificates contained in the certificate bundle.

DESCRIPTION

This function accepts as input a certificate bundle (a codified and signed aggregation of the certificates in the group), verifies the signature of the bundle (if a signature is present), and returns a certificate group (as an array of individual certificates) including every certificate contained in the bundle. The signature on the certificate aggregate is verified using the cryptographic context and possibly using the input signer certificate. The CL module embeds the knowledge of the verification scope for the bundle types that it supports. A CL module's supported bundle types and encodings are available to applications by querying the CSSM registry. The type and encoding of the certificate bundle must be specified with the input bundle. If signature verification is successful, the certificate aggregate will be parsed into a certificate group whose order corresponds to the certificate aggregate ordering. This certificate group will then be returned to the calling application.

RETURN VALUE

A CSSM_RETURN value indicating success or specifying a particular error condition. The value CSSM_OK indicates success. All other values represent an error condition.

ERRORS

Errors are described in the CDSA Technical Standard.
