[Openca-Users] Definition of TEXT and LATIN1_LETTER syntax

[Joachim S. <js...@ac...>]

Hello,

In basic request creation and elsewhere, request fields are tagged as
being LATIN1_LETTER (if one doesn't use UTF-8).

In OpenCA::TRIStateCGI the corresponding check is defined. It excludes
the characters [\]^_`{|}~ from entries. The same is done for fields
with TEXT syntax.

Why?

This prevents the usage of basic requests for servers that may have an
underscore (_) in their cn. There is also no obvious reasoning behind
allowing ( and ), but not [ and ], or ' but not `. Can please somebody
explain this irregular behaviour?

According to RFC2252, these fields are printable strings. Therefore,
in theory, one should simply use the regexp [:print:]+ for them,
though this might need more control over locales. Therefore, I would
assume that [\x20-\x7E\xA0-\xFF]+ is the most robust regexp for
LATIN1_LETTER. Similar for TEXT, btw -- this regexp is also obviously
wrong. LETTER is also strange, as it contains punctuation signs from
\xA0 to \xBF.

I am highly interested in any enlightening comments, as I'll change
that for a deployment next Monday and would like to know if I destroy
here something, owing to my not-enough knowledge. ;-)

	Joachim
