ECC signing + verification using sign_raw and verify_raw is flaky, it sometimes fails for no reason.
Steps to reproduce:
def test_ecc_sign_verify_raw_many():
for i in range(10000):
private_key = EccPrivate.make_key(48)
public_key = EccPublic()
qx, qy, _ = private_key.encode_key_raw()
public_key.decode_key_raw(qx, qy, curve_id=ECC_SECP384R1)
plaintext = "Everyone gets Friday off."
r, s = private_key.sign_raw(plaintext)
assert public_key.verify_raw(r, s, plaintext), f"signature should be valid (iteration {i})"Add this to test_ciphers.py. Observe that this test always fails, but the iteration number at which it fails varies, mostly within 150 attempts.
Expected behavior: sign + verify of the same data with the same key and signature is always successful.
