/**
* End-to-end RSA encryption and decryption test using OTBN.
*
* IMPORTANT: This test is not a secure, complete, or reusable implementation of
* RSA; it is not even close to being production-ready. It is only meant as an
* end-to-end test for OTBN during the bringup phase.
*
* This test loads the RSA application into OTBN, sets all required input
* arguments, and performs the encryption and decryption operations.
*
* To keep the test execution time reasonable some parts of the test can be
* disabled with the `kTestDecrypt` and `kTestRsaGreater1k` constants.
*
* The test contains constants and expected output, which can be independently
* and conveniently verified using a Python script.
*
* <code>
* # Optional: generate a new key
* $ openssl genpkey -algorithm RSA -out otbn_rsa_test_private_key_1024.pem \
* -pkeyopt rsa_keygen_bits:1024
*
* # Create all constants/variables
* $ ./otbn_test_params.py rsa otbn_rsa_test_private_key_1024.pem \
* "Hello OTBN, can you encrypt and decrypt this for me?"
* </code>

/**
* Performs encrypt and decrypt operations. (Otherwise, only encrypt is done.)
*
* Encryption is reasonably fast in RSA, taking between 50 thousand instructions
* for RSA 512, up to 17 million instructions for RSA 4096.
* Assuming a typical Verilator-based simulation of Earl Grey at 5 kHz, this
* results in simulation times between a couple of seconds and an hour for RSA
* encrypt.
*
* Decryption, on the other hand, is much more computationally expensive.
* Decryption takes around 0.5 million instructions for RSA 512, up to
* 128 million instructions for RSA 4096. Assuming the same simulation at 5 kHz,
* this translates to a RSA 512 decode taking around two minutes to execute,
* and a RSA 4096 decode taking over seven hours.
