Subject: [PATCH v4 5/7] ssh signing: make verify-tag consider key lifetime
Date: Tue, 30 Nov 2021 15:11:10 +0100 [thread overview]
Message-ID: <20211130141112.78193-6-fs@gigacodes.de> (raw)
In-Reply-To: <20211130141112.78193-1-fs@gigacodes.de>
Set the payload_type for check_signature() when calling verify-tag.
Implements the same tests as for verify-commit.
