Comment 1 Randy Barlow 2018-03-25 15:22:54 UTC 
FESCo has declared this to be a F28 final blocker.
Comment 2 Florian Weimer 2018-03-25 21:31:30 UTC 
Is anyone working on the port?

> Is anyone working on the port?

I will take it. It seems the libxcrypt is nogo, thus we need to use openssl. There is already alternative openssl code in the pppcrypt.c, but unfortunately it seems unmaintained and for ancient openssl version. I will try to rewrite it for recent openssl during tomorrow (2018-03-27). It shouldn't be hard.

per #c1 . Randy, note for the future: marking it as Blocks: FinalBlocker only marks it as a *proposed* blocker, to mark it as *accepted*, you also need the whiteboard field.

Unit test

This is very simple unit test I used inline with hardcoded randomly generated plain text and key (I used several plain texts and keys, the following is result for the plain text and key which is currently hardcoded in the attachement).

Fedora 26 with libcrypt / glibc:
11b4ec5ab7bdb881
c060b3a810ef79fb
11b4ec5ab7bdb881

Fedora 29/rawhide with openssl:
11b4ec5ab7bdb881
c060b3a810ef79fb
11b4ec5ab7bdb881

The meaning:
plain text in hex
encrypted data in hex
decrypted plain text in hex

Of course the test could be polished, but it should be sufficient for the purpose of this bugzilla.

Comment 9 Florian Weimer 2018-03-27 15:31:05 UTC 
Would you please put the fix into Fedora 28 as well?  You will have to file a Bodhi update for this.
