在Android 6.0上抛出java.security.ProviderException:with KeyPairGenerator.generateKeyPair（）

在运行Android 6.0的设备上已经发生过多次崩溃，但以下情况除外。密钥生成方法正在崩溃，出现以下异常。keyPairGenerator.generateKeyPair（）方法调用正在发生

请查找下面的代码，它在keyPairGenerator.generateKeyPair（）方法处崩溃。

@TargetApi(Build.VERSION_CODES.M)
    static void createKeysM(String alias, boolean requireAuth) {
        try {
            KeyPairGenerator keyPairGenerator = KeyPairGenerator.getInstance(
                    KeyProperties.KEY_ALGORITHM_RSA, SecurityConstants.KEYSTORE_PROVIDER_ANDROID_KEYSTORE);
            keyPairGenerator.initialize(
                    new KeyGenParameterSpec.Builder(
                            alias,
                            KeyProperties.PURPOSE_ENCRYPT | KeyProperties.PURPOSE_DECRYPT)
                            .setAlgorithmParameterSpec(new RSAKeyGenParameterSpec(1024, F4))
                            .setBlockModes(KeyProperties.BLOCK_MODE_CBC)
                            .setEncryptionPaddings(KeyProperties.ENCRYPTION_PADDING_RSA_PKCS1)
                            .setDigests(KeyProperties.DIGEST_SHA256,
                                    KeyProperties.DIGEST_SHA384,
                                    KeyProperties.DIGEST_SHA512)
                            // Only permit the private key to be used if the user authenticated
                            // within the last five minutes.
                            .setUserAuthenticationRequired(requireAuth)
                            .build());
            KeyPair keyPair = keyPairGenerator.generateKeyPair();
            Log.d(TAG, "Public Key is: " + keyPair.getPublic().toString());

        } catch (NoSuchProviderException | NoSuchAlgorithmException | InvalidAlgorithmParameterException e) {
            throw new RuntimeException(e);
        }
    }
