OSSL_ESS_CHECK_SIGNING_CERTS(3ossl) OpenSSL
NAME
OSSL_ESS_signing_cert_new_init, OSSL_ESS_signing_cert_v2_new_init,
OSSL_ESS_check_signing_certs - Enhanced Security Services (ESS)
functions
SYNOPSIS
#include <openssl/ess.h>
ESS_SIGNING_CERT *OSSL_ESS_signing_cert_new_init(const X509 *signcert,
const STACK_OF(X509) *certs,
int set_issuer_serial);
ESS_SIGNING_CERT_V2 *OSSL_ESS_signing_cert_v2_new_init(const EVP_MD *hash_alg,
const X509 *signcert,
const
STACK_OF(X509) *certs,
int set_issuer_serial);
int OSSL_ESS_check_signing_certs(const ESS_SIGNING_CERT *ss,
const ESS_SIGNING_CERT_V2 *ssv2,
const STACK_OF(X509) *chain,
int require_signing_cert);
DESCRIPTION
OSSL_ESS_signing_cert_new_init() generates a new ESS_SIGNING_CERT
structure referencing the given signcert and any given further certs
using their SHA-1 fingerprints. If set_issuer_serial is nonzero then
also the issuer and serial number of signcert are included in the
ESS_CERT_ID as the issuerSerial field. For all members of certs the
issuerSerial field is always included.
OSSL_ESS_signing_cert_v2_new_init() is the same as
OSSL_ESS_signing_cert_new_init() except that it uses the given hash_alg
and generates a ESS_SIGNING_CERT_V2 structure with ESS_CERT_ID_V2
elements.
OSSL_ESS_check_signing_certs() checks if the validation chain chain
contains the certificates required by the identifiers given in ss
and/or ssv2. If require_signing_cert is nonzero, ss or ssv2 must not
be NULL. If both ss and ssv2 are not NULL, they are evaluated
independently. The list of certificate identifiers in ss is of type
ESS_CERT_ID, while the list contained in ssv2 is of type
ESS_CERT_ID_V2. As far as these lists are present, they must be
nonempty. The certificate identified by their first entry must be the
first element of chain, i.e. the signer certificate. Any further
certificates referenced in the list must also be found in chain. The
matching is done using the given certificate hash algorithm and value.
In addition to the checks required by RFCs 2624 and 5035, if the
issuerSerial field is included in an ESSCertID or ESSCertIDv2 it must
match the certificate issuer and serial number attributes.
NOTES
ESS has been defined in RFC 2634, which has been updated in RFC 5035
(ESS version 2) to support hash algorithms other than SHA-1. This is
used for TSP (RFC 3161) and CAdES-BES (informational RFC 5126).
RETURN VALUES
OSSL_ESS_signing_cert_new_init() and
TS_VERIFY_CTX_set_certs(3), CMS_verify(3)
