| * 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> |

| * |
| * 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, |
