I run a small server "out in the cloud" on which I use fwknopd to enable SSH logins. Recently, on performing "emerge @world", dev-libs/libgcrypt was updated from version 1.6.5 to 1.7.0. This update caused my running instance of fwknopd to fail with the message:

Code:

gpg: Libgcrypt warning: AES-CTR-128 test failed (plaintext mismatch, diff: 0)

I verified that it was the updated version of libgcrypt by downgrading to version 1.6.5 and successfully decrypting the SPA packet sent by fwknop.

Needless to say, fwknopd did not open a hole in my firewall with dev-libs/libgcrypt-1.7.0 installed (fortunately, I have a VPN as a backup).

The warning message (above) doesn't make much sense to me and I didn't see any recent bugs on https://bugs.gentoo.org/buglist.cgi?quicksearch=ALL%20libgcrypt.

Has anyone else seen odd behavior in GnuPG since updating dev-libs/libgcrypt to version 1.7.0?

Thanks!
