The rsabigexponent test is used to check max-rsa-exponent-size.
We only run this test on builds without PKCS#11, as we have control over
the RSA exponent size with plain OpenSSL. We have not explored how to do
this with PKCS#11, which would require generating such a key and then
signing a zone with it. Additionally, even with control of the exponent
size with PKCS#11, generating a DNSKEY with this property and signing
such a zone would be slow and undesirable for each test run; instead, we
use a pregenerated DNSKEY and a saved signed zone. These are located in
rsabigexponent/ns2 and currently use RSASHA1 for the DNSKEY
algorithm; however, that may need to be changed in the future.
To generate the DNSKEY used in this test, we used bigkey.c, as
dnssec-keygen is not capable of generating such keys.
Do not remove bigkey.c as it may be needed to generate a new
DNSKEY for testing purposes.
bigkey is used to both test that we are not running under PKCS#11 and
generate a DNSKEY key with a large RSA exponent.
