+Subject: [PATCH] tests: Modify sample key to be 2048 bit rather than only 2033
+ bit
+
+The generated sample keys started with 00010203, thus leaving the upper
+15 bits of the key as '0', which in turn causes gnutls to think that the
+key is only 2033 bit long, thus rejecting certificate verification once
+the min-verification-profile is set to 'medium' in gnutls's config file
+in /etc/crypto-policies/back-ends/gnutls.config.
+
+We now create sample keys starting with 800102, which sets the highest bit.
+
+This fixes test errors on Fedora Rawhide due to the change in the
+min-verification-profile setting in gnutls.config.
