如何在jruby9.1.2.0中使用gpg加密来加密文件?

Pra*_*vin 11 java encryption bouncycastle ruby-on-rails openpgp

我试图使用gpg加密加密文件,然后在我的jruby项目中发送它.但是我找不到足够的资源.我尝试使用ruby-gpgme,但jruby不支持C库.我试过阅读Bouncy Castle,但我被课程文档所震撼,并没有找到加密文件的简单文章.

Vivek在这个问题上的答案接近我的解决方案,但只有解密文件的解决方案.我目前正在关注这篇文章并试图在jruby中连接java代码无济于事.我认为encryptFile功能是我需要的,如下所示:

public static void encryptFile(
        OutputStream out,
        String fileName,
        PGPPublicKey encKey,
        boolean armor,
        boolean withIntegrityCheck)
        throws IOException, NoSuchProviderException, PGPException
    {
        Security.addProvider(new BouncyCastleProvider());

        if (armor) {
            out = new ArmoredOutputStream(out);
        }

        ByteArrayOutputStream bOut = new ByteArrayOutputStream();
        PGPCompressedDataGenerator comData = new PGPCompressedDataGenerator(PGPCompressedData.ZIP);

        PGPUtil.writeFileToLiteralData(
                comData.open(bOut),
                PGPLiteralData.BINARY,
                new File(fileName) );

        comData.close();

        BcPGPDataEncryptorBuilder dataEncryptor = new BcPGPDataEncryptorBuilder(PGPEncryptedData.TRIPLE_DES);
        dataEncryptor.setWithIntegrityPacket(withIntegrityCheck);
        dataEncryptor.setSecureRandom(new SecureRandom());

        PGPEncryptedDataGenerator encryptedDataGenerator = new PGPEncryptedDataGenerator(dataEncryptor);
        encryptedDataGenerator.addMethod(new BcPublicKeyKeyEncryptionMethodGenerator(encKey));

        byte[] bytes = bOut.toByteArray();
        OutputStream cOut = encryptedDataGenerator.open(out, bytes.length);
        cOut.write(bytes);
        cOut.close();
        out.close();
    }

我收到以下错误:

如果你可以在整个jruby中使用gpg帮助我使用代码或加密文件,那将是一个很大的帮助.

更新1 ZIP值结果为整数值的常量,并在页面中列出.

更新2 我直到功能:

PGPEncryptedDataGenerator encryptedDataGenerator = new PGPEncryptedDataGenerator(dataEncryptor);
    encryptedDataGenerator.addMethod(new BcPublicKeyKeyEncryptionMethodGenerator(encKey)); // encKey is class PGPPublicKey's instance

我有从OS生成的公钥.如何encKey从我拥有的公钥字符串创建PGPPublic Key实例?

我找不到足够的答案或 gem 来执行此操作,包括项目文件夹中的 pgp 库。因此,我将此存储库分叉到此存储库以连接 Rails 和系统的 gpg 库。它可以在 ubuntu 上运行。我没有在其他机器上测试过。

加密:

在安装了公钥的机器上

encryptObj = Gpgr::Encrypt::GpgFileForEncryption.new
encryptObj.email_address = <email_of_gpg_owner>
encryptObj.file = <path_to_file_to_encrypt>
encryptObj.file_output = <path_to_output_file>
encryptObj.encrypt

解密

在拥有私钥的机器中

decryptObj = Gpgr::Decrypt::GpgFileForDecryption.new
decryptObj.file = <path_to_file_to_decrypt>
decryptObj.file_output = <path_to_output_file>
decryptObj.decrypt
