I've been gone for a long while, so excuse me if I'm jumping in here
without knowing what it is I'm talking about. =) All my SVN email
is queued up and I'll try to get at it soon-ish.
Anyway, I'm not really sure what you are talking about. The digest
should be returned as "unsigned char digest[MD5_DIGESTSIZE]" which
is 16 7-bit chars (unless I'm doing my math wrong too). So, that
seems like the long format. What is the output that you are getting
and what would you like it to be?
I believe it can be any of the 7-bit chars, which may cause a problem
for XML - just passing it through the escaper should do the trick
before writing it out to a file, right? You could also translate
each 7-bit char into a corresponding hex digit (which is what
md5sum et al do). Therefore, all you have is [0-9a-f] which XML
won't have a problem with.
apr_xlate is for EBCDIC which is something I don't *think* we're
focusing on here in SVN. If one of the IBMers wants to make it
run on the Big Blue, they can do that, but I don't think that's
going to help you make it all nice and pretty. -- justin
