我正在尝试使用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。我尝试阅读Bouncy Castle,但我被课程文档所震撼,并没有找到一篇加密文件的简单文章。
Vivek在this问题中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this article并试图在jruby中连接java代码无济于事。我认为encryptFile
函数是我需要的函数,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:
NoMethodError: undefined method `ZIP' for Java::OrgBouncycastleOpenpgp::PGPCompressedData:Class
at
PGPCompressedDataGenerator comData = new PGPCompressedDataGenerator(PGPCompressedData.ZIP);
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,并列在this页面中。
更新2 我做到了这个功能:
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。如何从我拥有的公钥字符串创建PGPPublic Key实例encKey
?
