使用Bouncy Castle从.pfx文件读取私钥-获取java.lang.VerifyError

Question

当我从.pfx文件中读取私钥以对字符串进行签名时，必须在其中使用BouncyCastleProvider作为安全提供程序。

错误抛出位置：
KeyStore.getInstance（“ PKCS12”，新的BouncyCastleProvider（）。getName（））

代码段：

        String message = jsonString;
        String password = "XXXX";
        Security.addProvider(new BouncyCastleProvider());
        logger.severe("message : " + message);
        File pfxFile = new file("/XXXX/XXXX/XXXX.pfx");
        KeyStore keyStore = KeyStore.getInstance("PKCS12", new BouncyCastleProvider().getName()); //here getting error
        logger.severe("keyStore : " + keyStore);
        keyStore.load(new FileInputStream(pfxFile), password.toCharArray());
        String alias = (String) keyStore.aliases().nextElement();
        PrivateKey privateKey = (PrivateKey) keyStore.getKey(alias, password.toCharArray());
        Signature privateSignature = Signature.getInstance("SHA256withRSA");
        privateSignature.initSign(privateKey);
        privateSignature.update(message.getBytes("UTF-8"));
        byte[] signature2 = privateSignature.sign();
        String smsgContent = SHA256SignerUtil.encodeBase64String(signature2);

错误摘要：
