+specifying an engine (by its unique B<id> string) will cause B<x509>
to attempt to obtain a functional reference to the specified engine,
thus initialising it if needed. The engine will then be set as the default

this option prevents output of the encoded version of the request.
+=item B<-pubkey>
+
+outputs the the certificate's SubjectPublicKeyInfo block in PEM format.
+
=item B<-modulus>
this option prints out the value of the modulus of the public key
outputs the "hash" of the certificate issuer name.
+=item B<-ocspid>
+
+outputs the OCSP hash values for the subject name and public key.
+
=item B<-hash>
synonym for "-subject_hash" for backward compatibility reasons.
+=item B<-subject_hash_old>
+
+outputs the "hash" of the certificate subject name using the older algorithm
+as used by OpenSSL versions before 1.0.0.
+
+=item B<-issuer_hash_old>
+
+outputs the "hash" of the certificate issuer name using the older algorithm

+
=item B<-subject>
outputs the subject name.
outputs the email address(es) if any.
+=item B<-ocsp_uri>
+
+outputs the OCSP responder address(es) if any.
+
=item B<-startdate>
prints out the start date of the certificate, that is the notBefore date.
prints out the start and expiry dates of a certificate.
+=item B<-checkend arg>
+
+checks if the certificate expires within the next B<arg> seconds and exits
+non-zero if yes it will expire or zero if not.

=item B<-fingerprint>
prints out the digest of the DER encoded version of the whole certificate

+
+the key password source. For more information about the format of B<arg>

=item B<-clrext>
delete any extensions from a certificate. This option is used when a

+=item B<-force_pubkey key>
+
+when a certificate is created set its public key to B<key> instead of the

Before OpenSSL 0.9.8, the default digest for RSA keys was MD5.
+The hash algorithm used in the B<-subject_hash> and B<-issuer_hash> options
+before OpenSSL 1.0.0 was based on the deprecated MD5 algorithm and the encoding
+of the distinguished name. In OpenSSL 1.0.0 and later it is based on a
+canonical version of the DN using SHA1. This means that any directories using
+the old form must have their links rebuilt using B<c_rehash> or similar.
