Can you replace this with a call to requireShake256?
| KeyPairGenerator keyPairGenerator = KeyPairGenerator.getInstance(curve); | ||
| keyPairGenerator.initialize(new NamedParameterSpec(curve), new SecureRandom() { | ||
| public void nextBytes(byte[] bytes) { | ||
| System.arraycopy(privateKey, 0, bytes, 0, privateKey.length); |
