Sean Parkinson c905033acf API tests: more cipher tests 
1. Unaligned Buffer Tests
Verify correct output when input/output buffers are byte-offset by 1,
2, and 3 bytes.
  - AES-CBC, AES-CTS, AES-CTR, AES-GCM, AES-CCM, AES-XTS
- ChaCha20, ChaCha20-Poly1305

2. In-Place (Overlapping) Buffer Tests
Verify correct output when out == in (same pointer for input and
output).
  - AES-CTS, AES-GCM, AES-CCM, AES-XTS
- ChaCha20, ChaCha20-Poly1305

3. Cross-Cipher Verification Tests
Verify that a higher-level mode produces identical output when
manually reconstructed from a lower-level primitive (typically AES-ECB +
XOR).
- AES-CBC (= ECB + XOR chaining)
- AES-CFB (= ECB(ciphertext feedback) + XOR)
  - AES-OFB (= ECB(output feedback) + XOR)
- AES-CTR (= ECB(counter) + XOR with big-endian increment)
  - AES-GCM (ciphertext portion = CTR starting at counter J0+1)
- ChaCha20-Poly1305 (ciphertext = raw ChaCha20 keystream XOR; tag =
independent Poly1305)

4. Counter Overflow Tests
Verify correct carry propagation when the internal block counter wraps
around.
  - AES-CTR (32-bit big-endian carry across 4 bytes: 0xFFFFFFFE → wrap)
- ChaCha20 (32-bit counter: 0xFFFFFFFF → 0x00000000)

5. AEAD Edge Case Tests
Verify correct behavior for empty inputs, empty AAD, and invalid auth
tag rejection.
  - Ascon-AEAD128
  - AES-CCM
  - ChaCha20-Poly1305

6. Non-Standard Parameter Tests
  Verify behavior outside the common fast path.
- AES-GCM: non-96-bit nonce lengths (1-byte, 60-byte, variable-length
loop, zero-length rejection)

7. Streaming API State Tests
Verify mid-stream state behavior and re-initialization after a final
call.
  - AES-GCM stream, AES-XTS stream
  - ChaCha20-Poly1305 stream

Sean Parkinson 59a17dd598 Unit testing: Add Monte Carlo testing to ciphers 
Monte Carlo testing is randomized test data.
These new tests have random keys, IVs, nonce, etc and random data to
encrypt.
100 sets of random test data are encrypted and decrypted with a check to
ensure the input to encrypt is the same as the output of decrypt.
Tags are generated and checked in the calls to encrypt and decrypt.

Sean Parkinson 883ceecf8a ChaCha20 Aarch64 ASM fix: 256-bit case fixed 
Fixed the 256-bits at a time crypt assembly code.

Add a chunking test for ChaCha20.

Sean Parkinson 663ca29a5d Split out tests: random, wolfmath, public key 
Improved testing of random APIs.
wolfmath tests moved out.
Public key algorithm testing moved out: RSA, DSA, DH, ECC, SM2,
Curve25519, Ed25519, Curve448, Ed448, ML-DSA.
Signature API tests moved out.

Fix for OCSP testing to ensure RSA is available.

Added group names to API test cases.
Can select groups to run with --group <name>. --groups lists all known
group names.

Added option to stop API testing on first failure: --stopOnFail.
