There's more to correctly implementing RSA than simply
correctly implementing PKCS-1. Consequently, PKCS-1 test
vectors don't do the whole job.
The tricky bit is correctly generating the key. I don't know
of any test vectors for this, a la the test vectors in FIPS-186a
for DSS parameter and key generation.
