Question

我正在尝试在android中使用jwt身份验证实现box-java-sdk。当sdk试图在这些行中解密私钥时：

InputDecryptorProvider pkcs8Prov = new JceOpenSSLPKCS8DecryptorProviderBuilder().setProvider("BC")
                                   .build(this.privateKeyPassword.toCharArray());
PrivateKeyInfo keyInfo =  ((PKCS8EncryptedPrivateKeyInfo) keyPair).decryptPrivateKeyInfo(pkcs8Prov);
decryptedPrivateKey = (new JcaPEMKeyConverter()).getPrivateKey(keyInfo);

发生以下异常：

虽然这个sdk在标准的java应用程序中运行良好。 Android的BountyCastle提供程序的实现有什么变化吗？这个问题有解决方法吗？

Answer 1

通过首先删除BountyCastle的Android实现来实现它：

Security.removeProvider(BouncyCastleProvider.PROVIDER_NAME);

因此注册BouncyCastleProvider的静态块变为：

static {
    Security.removeProvider(BouncyCastleProvider.PROVIDER_NAME);
    Security.addProvider(new BouncyCastleProvider());
}

Bouncy Castle提供程序在标准java中工作时抛出NoSuchAlgorithmException
