Do not load the trusted CA certificates from the default directory location
+=item B<-allow_proxy_certs>
+
+Allow the verification of proxy certificates
+
=item B<-attime timestamp>
Perform validation checks using time specified by B<timestamp> and not
Set policy variable inhibit-policy-mapping (see RFC5280).
+=item B<-no_check_time>
+
+This option suppresses checking the validity period of certificates and CRLs
+against the current time. If option B<-attime timestamp> is used to specify
+a verification time, the check is not suppressed.
+
=item B<-partial_chain>
Allow verification to succeed even if a I<complete> chain cannot be built to a
A B<file> of additional untrusted certificates (intermediate issuer CAs) used
to construct a certificate chain from the subject certificate to a trust-anchor.
The B<file> should contain one or more certificates in PEM format.
-This option can be specified more than once to include untrusted certiificates
+This option can be specified more than once to include untrusted certificates
from multiple B<files>.
=item B<-trusted file>
A B<file> of trusted certificates, which must be self-signed, unless the
B<-partial_chain> option is specified.
-The B<file> contain one or more certificates in PEM format.
+The B<file> contains one or more certificates in PEM format.
With this option, no additional (e.g., default) certificate lists are
consulted.
That is, the only trust-anchors are those listed in B<file>.
Print extra information about the operations being performed.
+=item B<-auth_level level>
+
+Set the certificate chain authentication security level to B<level>.
+The authentication security level determines the acceptable signature and
+public key strength when verifying certificate chains.
+For a certificate chain to validate, the public keys of all the certificates
+must meet the specified security B<level>.
+The signature algorithm security level is enforced for all the certificates in
+the chain except for the chain's I<trust anchor>, which is either directly
+trusted or validated by means other than its signature.
+See L<SSL_CTX_set_security_level(3)> for the definitions of the available
+levels.
+The default security level is -1, or "not set".
+At security level 0 or lower all algorithms are acceptable.
+Security level 1 requires at least 80-bit-equivalent security and is broadly
+interoperable, though it will, for example, reject MD5 signatures or RSA keys
+shorter than 1024 bits.
+
=item B<-verify_depth num>
-Limit the maximum depth of the certificate chain to B<num> certificates.
+Limit the certificate chain to B<num> intermediate CA certificates.
+A maximal depth chain can have up to B<num+2> certificates, since neither the
+end-entity certificate nor the trust-anchor certificate count against the
+B<-verify_depth> limit.
=item B<-verify_email email>
The process of 'looking up the issuers certificate' itself involves a number of
steps.
-Ater all certificates whose subject name matches the issuer name of the current
+After all certificates whose subject name matches the issuer name of the current
certificate are subject to further tests.
The relevant authority key identifier components of the current certificate (if
present) must match the subject key identifier (if present) and issuer and
then 1 for the CA that signed the certificate and so on. Finally a text version
of the error number is presented.
-An partial list of the error codes and messages is shown below, this also
+A partial list of the error codes and messages is shown below, this also
includes the name of the error code as defined in the header file x509_vfy.h
Some of the error codes are defined but never returned: these are described
as "unused".
