java.security.InvalidKeyException：密钥库操作失败

Question

我得到java.security.InvalidKeyException: Keystore operation failed. 有没有人有想法？这是我的代码：

initDecodeCipher 的代码：

private static void initDecodeCipher(int mode) throws KeyStoreException, NoSuchAlgorithmException, UnrecoverableEntryException, InvalidKeyException, NoSuchPaddingException {

    KeyStore.PrivateKeyEntry privateKeyEntry = (KeyStore.PrivateKeyEntry) sKeyStore.getEntry(FINGERPRINT_KEY_NAME, null);
    Cipher output = Cipher.getInstance(TRANSFORMATION);
    output.init(Cipher.DECRYPT_MODE, privateKeyEntry.getPrivateKey());
}

initEncodeCipher 的代码：

private static void initEncodeCipher(int mode) throws KeyStoreException, InvalidKeySpecException, NoSuchAlgorithmException, InvalidKeyException, InvalidAlgorithmParameterException {
    PublicKey key = sKeyStore.getCertificate(FINGERPRINT_KEY_NAME).getPublicKey();

    PublicKey unrestricted = KeyFactory.getInstance(key.getAlgorithm()).generatePublic(new X509EncodedKeySpec(key.getEncoded()));
    OAEPParameterSpec spec = new OAEPParameterSpec("SHA-256", "MGF1", MGF1ParameterSpec.SHA1, PSource.PSpecified.DEFAULT);

    sCipher.init(mode, unrestricted, spec);
}

生成新密钥的代码：

@TargetApi(Build.VERSION_CODES.M)
private static boolean generateNewKey() {

    if (getKeyPairGenerator()) {

        try {
            sKeyPairGenerator.initialize(
                    new KeyGenParameterSpec.Builder(FINGERPRINT_KEY_NAME, KeyProperties.PURPOSE_ENCRYPT | KeyProperties.PURPOSE_DECRYPT)
                            .setDigests(KeyProperties.DIGEST_SHA256, KeyProperties.DIGEST_SHA512)
                            .setEncryptionPaddings(KeyProperties.ENCRYPTION_PADDING_RSA_OAEP)
                            .setUserAuthenticationRequired(true)
                            .build());
            sKeyPairGenerator.generateKeyPair();
            return true;
        } catch (InvalidAlgorithmParameterException e) {
            e.printStackTrace();
        }
    }
    return false;
}

错误：

使用的算法：

private static final String ALGORITHM= KeyProperties.KEY_ALGORITHM_RSA;
private static final String TRANSFORMATION = ALGORITHM+"/ECB/OAEPWithSHA-256AndMGF1Padding";

请不要评判我强，我是加密新手。我已经尝试了 Stackoverflow 的几个答案，但没有结果。

如果其他人通过 Google 到达这里：

在抛出的异常中，检查“原因”变量。这将为您提供所需的详细信息。在上面的例子中，问题很可能是“不兼容的填充模式”
