Current CMS en/decryption tests only validate that our current decyption
and encryption algorithms are compatible, but they say nothing about
correctness of the output for the given set of parameters.

As a partial fix in absence of proper KAT tests, we decrypt ciphertexts
generated with OpenSSL 1.1.1.
