Module aes256 

Test the AES hardware for ECB, CBC, and CTR modes using NIST SP 800-38A vectors.

Each test struct runs the following steps in sequence:

1. StandardEnc — out-of-place encryption, full message
2. StandardEncInPlace — in-place encryption, full message
3. StandardDec — out-of-place decryption, full message (if test_decrypt)
4. StandardDecInPlace — in-place decryption, full message (if test_decrypt)
5. ChunkEnc1 — in-place encryption, first half
6. ChunkEnc2 — in-place encryption, second half (no re-init, tests IV chaining)
7. ChunkDec1 — in-place decryption, first half (if test_decrypt)
8. ChunkDec2 — in-place decryption, second half (if test_decrypt)
