| |
| =head1 SYNOPSIS |
| |
| B<openssl> |
| I<command> |
| [ I<options> ... ] |
| [ I<parameters> ... ] |
| |
| =head1 DESCRIPTION |
| |
| OpenSSL provides fine-grain control over how the subject and issuer DN's are |
| displayed. |
| This is specified by using the B<-nameopt> option, which takes a |
| comma-separated list of options from the following set. |
| An option may be preceded by a minus sign, C<->, to turn it off. |
| The default value is C<utf8,sep_comma_plus_space>. |
| The first four are the most commonly used. |
| |
| =head1 OPTIONS |
| |
| =head2 Name Format Option Arguments |
| |
| The DN output format can be fine tuned with the following flags. |
| |
| =over 4 |
| |
| =item B<compat> |
| |
| Display the name using an old format from previous OpenSSL versions. |
| |
| =item B<RFC2253> |
| |
| Display the name using the format defined in RFC 2253. |
| It is equivalent to B<esc_2253>, B<esc_ctrl>, B<esc_msb>, B<utf8>, |
| B<dump_nostr>, B<dump_unknown>, B<dump_der>, B<sep_comma_plus>, B<dn_rev> |
| and B<sname>. |
| |
| =item B<oneline> |
| |
| Display the name in one line, using a format that is more readable |
| RFC 2253. |
| It is equivalent to B<esc_2253>, B<esc_ctrl>, B<esc_msb>, B<utf8>, |
| B<dump_nostr>, B<dump_der>, B<use_quote>, B<sep_comma_plus_space>, |
| B<space_eq> and B<sname> options. |
| |
| =item B<multiline> |
| |
| Display the name using multiple lines. |
| It is equivalent to B<esc_ctrl>, B<esc_msb>, B<sep_multiline>, B<space_eq>, |
| B<lname> and B<align>. |
| |
| =item B<esc_2253> |
| |
| Escape the "special" characters in a field, as required by RFC 2253. |
| That is, any of the characters C<,+"E<lt>E<gt>;>, C<#> at the beginning of |
| a string and leading or trailing spaces. |
| |
| =item B<esc_2254> |
| |
| Escape the "special" characters in a field as required by RFC 2254 in a field. |
| That is, the B<NUL> character and of C<()*>. |
| |
| =item B<esc_ctrl> |
| |
| Escape non-printable ASCII characters, codes less than 0x20 (space) |
| or greater than 0x7F (DELETE). They are displayed using RFC 2253 C<\XX> |
| notation where B<XX> are the two hex digits representing the character value. |
| |
| =item B<esc_msb> |
| |
| Escape any characters with the most significant bit set, that is with |
| values larger than 127, as described in B<esc_ctrl>. |
| |
| =item B<use_quote> |
| |
| Escapes some characters by surrounding the entire string with quotation |
| marks, C<">. |
| Without this option, individual special characters are preceded with |
| a backslash character, C<\>. |
| |
| =item B<utf8> |
| |
| Convert all strings to UTF-8 format first as required by RFC 2253. |
| If the output device is UTF-8 compatible, then using this option (and |
| not setting B<esc_msb>) may give the correct display of multibyte |
| characters. |
| If this option is not set, then multibyte characters larger than 0xFF |
| will be output as C<\UXXXX> for 16 bits or C<\WXXXXXXXX> for 32 bits. |
| In addition, any UTF8Strings will be converted to their character form first. |
| |
| =item B<ignore_type> |
| |
| This option does not attempt to interpret multibyte characters in any |
| way. That is, the content octets are merely dumped as though one octet |
| represents each character. This is useful for diagnostic purposes but |
| will result in rather odd looking output. |
| |
| =item B<show_type> |
| |
| Display the type of the ASN1 character string before the value, |
| such as C<BMPSTRING: Hello World>. |
| |
| =item B<dump_der> |
| |
| Any fields that would be output in hex format are displayed using |
| the DER encoding of the field. |
| If not set, just the content octets are displayed. |
| Either way, the B<#XXXX...> format of RFC 2253 is used. |
| |
| =item B<dump_nostr> |
| |
| Dump non-character strings, such as ASN.1 B<OCTET STRING>. |
| If this option is not set, then non character string types will be displayed |
| as though each content octet represents a single character. |
| |
| =item B<dump_all> |
| |
| Dump all fields. When this used with B<dump_der>, this allows the |
| DER encoding of the structure to be unambiguously determined. |
| |
| =item B<dump_unknown> |
| |
| Dump any field whose OID is not recognised by OpenSSL. |
| |
| =item B<sep_comma_plus>, B<sep_comma_plus_space>, B<sep_semi_plus_space>, |
| B<sep_multiline> |
| |
| Specify the field separators. The first word is used between the |
| Relative Distinguished Names (RDNs) and the second is between |
| multiple Attribute Value Assertions (AVAs). Multiple AVAs are |
| very rare and their use is discouraged. |
| The options ending in "space" additionally place a space after the separator to make it more readable. |
| The B<sep_multiline> starts each field on its own line, and uses "plus space" |
| for the AVA separator. |
| It also indents the fields by four characters. |
| The default value is B<sep_comma_plus_space>. |
| |
| =item B<dn_rev> |
| |
| Reverse the fields of the DN as required by RFC 2253. |
| This also reverses the order of multiple AVAs in a field, but this is |
| permissible as there is no ordering on values. |
| |
| =item B<nofname>, B<sname>, B<lname>, B<oid> |
| |
| Specify how the field name is displayed. |
| B<nofname> does not display the field at all. |
| B<sname> uses the "short name" form (CN for commonName for example). |
| B<lname> uses the long form. |
| B<oid> represents the OID in numerical form and is useful for |
| diagnostic purpose. |
| |
| =item B<align> |
| |
| Align field values for a more readable output. Only usable with |
| B<sep_multiline>. |
| |
| =item B<space_eq> |
| |
| Places spaces round the equal sign, C<=>, character which follows the field |
| name. |
