DESCRIPTION
       These functions manipulate the X509_VERIFY_PARAM structure associated
       with a certificate verification operation.

       The X509_VERIFY_PARAM_set_flags() function sets the flags in param by
       oring it with flags. See the VERIFICATION FLAGS section for a complete
       description of values the flags parameter can take.

       X509_VERIFY_PARAM_get_flags() returns the flags in param.

       X509_VERIFY_PARAM_clear_flags() clears the flags flags in param.

       X509_VERIFY_PARAM_set_purpose() sets the verification purpose in param
       to purpose. This determines the acceptable purpose of the certificate
       chain, for example SSL client or SSL server.

       X509_VERIFY_PARAM_set_trust() sets the trust setting in param to trust.

       X509_VERIFY_PARAM_set_time() sets the verification time in param to t.
       Normally the current time is used.

       X509_VERIFY_PARAM_add0_policy() enables policy checking (it is disabled
       by default) and adds policy to the acceptable policy set.

       X509_VERIFY_PARAM_set1_policies() enables policy checking (it is
       disabled by default) and sets the acceptable policy set to policies.
       Any existing policy set is cleared. The policies parameter can be NULL
       to clear an existing policy set.

       X509_VERIFY_PARAM_set_depth() sets the maximum verification depth to
       depth.  That is the maximum number of untrusted CA certificates that
       can appear in a chain.

RETURN VALUES
       X509_VERIFY_PARAM_set_flags(), X509_VERIFY_PARAM_clear_flags(),
       X509_VERIFY_PARAM_set_purpose(), X509_VERIFY_PARAM_set_trust(),
       X509_VERIFY_PARAM_add0_policy() and X509_VERIFY_PARAM_set1_policies()
       return 1 for success and 0 for failure.

       X509_VERIFY_PARAM_get_flags() returns the current verification flags.

       X509_VERIFY_PARAM_set_time() and X509_VERIFY_PARAM_set_depth() do not
       return values.

       X509_VERIFY_PARAM_get_depth() returns the current verification depth.

VERIFICATION FLAGS
       The verification flags consists of zero or more of the following flags
       ored together.

       X509_V_FLAG_CRL_CHECK enables CRL checking for the certificate chain
       leaf certificate. An error occurs if a suitable CRL cannot be found.

       X509_V_FLAG_CRL_CHECK_ALL enables CRL checking for the entire
       certificate chain.

       X509_V_FLAG_IGNORE_CRITICAL disabled critical extension checking. By
       default any unhandled critical extensions in certificates or (if
       checked) CRLs results in a fatal error. If this flag is set unhandled
       critical extensions are ignored. WARNING setting this option for
       anything other than debugging purposes can be a security risk. Finer
       control over which extensions are supported can be performed in the
       verification callback.

       THe X509_V_FLAG_X509_STRICT flag disables workarounds for some broken
       certificates and makes the verification strictly apply X509 rules.

       X509_V_FLAG_ALLOW_PROXY_CERTS enables proxy certificate verification.

       X509_V_FLAG_POLICY_CHECK enables certificate policy checking, by
       default no policy checking is peformed. Additional information is sent
       to the verification callback relating to policy checking.

       X509_V_FLAG_EXPLICIT_POLICY, X509_V_FLAG_INHIBIT_ANY and
       X509_V_FLAG_INHIBIT_MAP set the require explicit policy, inhibit any
       policy and inhibit policy mapping flags respectively as defined in
       RFC3280. Policy checking is automatically enabled if any of these flags
       are set.

       If X509_V_FLAG_NOTIFY_POLICY is set and the policy checking is
       successful a special status code is set to the verification callback.
       This permits it to examine the valid policy tree and perform additional
       checks or simply log it for debugging purposes.

       By default some additional features such as indirect CRLs and CRLs
       signed by different keys are disabled. If
       X509_V_FLAG_EXTENDED_CRL_SUPPORT is set they are enabled.

       If X509_V_FLAG_USE_DELTAS ise set delta CRLs (if present) are used to
       determine certificate status. If not set deltas are ignored.

       X509_V_FLAG_CHECK_SS_SIGNATURE enables checking of the root CA self
       signed cerificate signature. By default this check is disabled because
       it doesn't add any additional security but in some cases applications
       might want to check the signature anyway. A side effect of not checking
       the root CA signature is that disabled or unsupported message digests
       on the root CA are not treated as fatal errors.

       The X509_V_FLAG_CB_ISSUER_CHECK flag enables debugging of certificate
       issuer checks. It is not needed unless you are logging certificate
       verification. If this flag is set then additional status codes will be
       sent to the verification callback and it must be prepared to handle
       such cases without assuming they are hard errors.

NOTES
       The above functions should be used to manipulate verification
       parameters instead of legacy functions which work in specific
       structures such as X509_STORE_CTX_set_flags().

BUGS
       Delta CRL checking is currently primitive. Only a single delta can be
       used and (partly due to limitations of X509_STORE) constructed CRLs are
       not maintained.

       If CRLs checking is enable CRLs are expected to be available in the
       corresponding X509_STORE structure. No attempt is made to download CRLs
       from the CRL distribution points extension.

EXAMPLE
       Enable CRL checking when performing certificate verification during SSL
       connections associated with an SSL_CTX structure ctx:

	 X509_VERIFY_PARAM *param;
	 param = X509_VERIFY_PARAM_new();
	 X509_VERIFY_PARAM_set_flags(param, X509_V_FLAG_CRL_CHECK);
	 SSL_CTX_set1_param(ctx, param);
	 X509_VERIFY_PARAM_free(param);
