+Hash: SHA256
+
+This is an example text file to demonstrate a problem.
+
+Using forged-keyring.gpg with signature cache, it looks like it is
+signed by the following key:
+
+    Echo Test (demo key) <echo at example.net>
+
+But actually not.
+
+It is signed by a key (steve.biko at example.net) distributed as:
+
+    gnupg/tests/openpgp/samplekeys/rsa-rsa-sample-1.asc
+
+in GnuPG.
+
+The forged-keyring.gpg file is created by a key in
+
+    gnupg/tests/openpgp/pubdemo.asc
+
+Replacing the raw key material packet by one of rsa-rsa-sample-1.asc.
