Re: Is guid_mode: sha1 really gone from imapd.conf?

Right. Sha1 is getting a bit ancient and Blake2 is used in Argon2 which won the most recent password hashing competition.

Thanks for your time and all your work.

For what it's worth, looking at commit history, it looks like it went

Yep, it's gone away - sha1 is the only mode right now.  We're going to
want to look at blake2 soon though I reckon.

So the subject is the question...

Running cyr_info conf-lint against our imapd.conf indicates "guid_mode"
is gone and indeed, the imapd.conf man page doesn't mention it now.

But many older versions of the man page do mention it and I can not find
any mention in past release notes at

http://www.cyrusimap.org/dev/imap/download/release-notes/index.html

of it being deprecated or removed.

So is it really gone or could it have been accidentally left out of the
man page and conf-lint check code? I agree that is very unlikely, but
with all the massive amount of excellent work that has been done by the
Cyrus team in the last few years, sometimes a small thing like this can
fall through a crack.

Hopefully it will be OK just to remove the "guid_mode" sha1" line and
restart and nothing will explode?

Thanks and my apologies if the above is a really dumb question.
