=item B<RFC2253>
a oneline format which is more readable than RFC2253. It is equivalent to
specifying the B<esc_2253>, B<esc_ctrl>, B<esc_msb>, B<utf8>, B<dump_nostr>,

a multiline format. It is equivalent B<esc_ctrl>, B<esc_msb>, B<sep_multiline>,
-B<sp

+B<sp
ace_eq>, B<lname> and B<align>.
=item B<esc_2253>
Also if this option is off any UTF8Strings will be converted to their
character form first.
-=item B<no_type>
+=item B<ignore_type>
this option does not attempt to interpret multibyte characters in any
way. That is their content octets are merely dumped as though one octet
align field values for a more readable output. Only usable with
B<sep_multiline>.
-=item B<spc_eq>
+=item B<space_eq>
places spaces round the B<=> character which follows the field
name.
Display the certificate subject name in oneline form on a terminal
supporting UTF8:
- openssl x509 -in cert.pem -noout -subject -nameopt oneline,-escmsb
+ openssl x509 -in cert.pem -noout -subject -nameopt oneline,-esc_msb
Display the certificate MD5 fingerprint:
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.
