Subject: [PATCH] gpg-interface: trim CR from ssh-keygen -Y find-principals
Date: Fri, 03 Dec 2021 13:31:16 +0000 [thread overview]
Message-ID: <pull.1090.git.1638538276608.gitgitgadget@gmail.com> (raw)
From: pedro martelletto <pedro@yubico.com>
We need to trim \r from the output of 'ssh-keygen -Y find-principals' on
Windows, or we end up calling 'ssh-keygen -Y verify' with a bogus signer
identity. ssh-keygen.c:2841 contains a call to puts(3), which confirms this
hypothesis. Signature verification passes with the fix.

Allow for CR in the output of ssh-keygen
This came in via https://github.com/git-for-windows/git/pull/3561. It
affects current Windows versions of OpenSSH (but apparently not the
MSYS2 version included in Git for Windows).
