=head1 NAME
|
|
|
|
OSSL_CMP_validate_msg,
|
|
OSSL_CMP_validate_cert_path
|
|
- functions for verifying CMP message protection
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
#include <openssl/cmp.h>
|
|
int OSSL_CMP_validate_msg(OSSL_CMP_CTX *ctx, OSSL_CMP_MSG *msg);
|
|
int OSSL_CMP_validate_cert_path(const OSSL_CMP_CTX *ctx,
|
|
X509_STORE *trusted_store, X509 *cert);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
This is the API for validating the protection of CMP messages,
|
|
which includes validating CMP message sender certificates and their paths
|
|
while optionally checking the revocation status of the certificates(s).
|
|
|
|
OSSL_CMP_validate_msg() validates the protection of the given I<msg>,
|
|
which must be signature-based or using password-based MAC (PBM).
|
|
In the former case a suitable trust anchor must be given in the CMP context
|
|
I<ctx>, and in the latter case the matching secret must have been set there
|
|
using L<OSSL_CMP_CTX_set1_secretValue(3)>.
|
|
|
|
In case of signature algorithm, the certificate to use for the signature check
|
|
is preferably the one provided by a call to L<OSSL_CMP_CTX_set1_srvCert(3)>.
|
|
If no such sender cert has been pinned then candidate sender certificates are
|
|
taken from the list of certificates received in the I<msg> extraCerts, then any
|
|
certificates provided before via L<OSSL_CMP_CTX_set1_untrusted(3)>, and
|
|
then all trusted certificates provided via L<OSSL_CMP_CTX_set0_trustedStore(3)>,
|
|
where a candidate is acceptable only if has not expired, its subject DN matches
|
|
the I<msg> sender DN (as far as present), and its subject key identifier
|
|
is present and matches the senderKID (as far as the latter present).
|
|
Each acceptable cert is tried in the given order to see if the message
|
|
signature check succeeds and the cert and its path can be verified
|
|
using any trust store set via L<OSSL_CMP_CTX_set0_trustedStore(3)>.
|
|
|
|
If the option OSSL_CMP_OPT_PERMIT_TA_IN_EXTRACERTS_FOR_IR was set by calling
|
|
L<OSSL_CMP_CTX_set_option(3)>, for an Initialization Response (IP) message
|
|
any self-issued certificate from the I<msg> extraCerts field may also be used
|
|
as trust anchor for the path verification of an acceptable cert if it can be
|
|
used also to validate the issued certificate returned in the IP message. This is
|
|
according to TS 33.310 [Network Domain Security (NDS); Authentication Framework
|
|
(AF)] document specified by the The 3rd Generation Partnership Project (3GPP).
|
|
|
|
Any cert that has been found as described above is cached and tried first when
|
|
validating the signatures of subsequent messages in the same transaction.
|
|
|
|
OSSL_CMP_validate_cert_path() attempts to validate the given certificate and its
|
|
path using the given store of trusted certs (possibly including CRLs and a cert
|
|
verification callback) and non-trusted intermediate certs from the I<ctx>.
|
|
|
|
=head1 NOTES
|
|
|
|
CMP is defined in RFC 4210 (and CRMF in RFC 4211).
|
|
|
|
=head1 RETURN VALUES
