WSO2 encrypt/decrypt 密码（字符串）和 public-私钥

Question

在 BAM 配置文件中的 WSO2 ESB (4.8.1) 中，当我导出它（BAM 配置文件）时，我注意到密码已加密。我发现如果我有私钥和 public 密钥，我可以 encrypt/decrypt 密码，所以我这样写：

import org.apache.commons.codec.binary.Base64;
import org.bouncycastle.jce.provider.BouncyCastleProvider;

import javax.crypto.Cipher;
import java.io.FileInputStream;
import java.security.*;
import java.security.cert.Certificate;

public class Main {
    public static void main(String[] argv) throws Exception {
        Security.addProvider(new BouncyCastleProvider());
        FileInputStream is = new FileInputStream("wso2carbon.jks");

        KeyStore keystore = KeyStore.getInstance(KeyStore.getDefaultType());
        keystore.load(is, "wso2carbon".toCharArray());

        String alias = "wso2carbon";

        Key key = keystore.getKey(alias, "wso2carbon".toCharArray());
        if (key instanceof PrivateKey) {
            Certificate cert = keystore.getCertificate(alias);

            PublicKey publicKey = cert.getPublicKey();

            String dataToBeEncrypted = "admin";
            String adminToDecrypted = "kuv2MubUUveMyv6GeHrXr9il59ajJIqUI4eoYHcgGKf/BBFOWn96NTjJQI+wYbWjKW6r79S7L7ZzgYeWx7DlGbff5X3pBN2Gh9yV0BHP1E93QtFqR7uTWi141Tr7V7ZwScwNqJbiNoV+vyLbsqKJE7T3nP8Ih9Y6omygbcLcHzg=";

            Cipher cipher = Cipher.getInstance("RSA");

            cipher.init(Cipher.ENCRYPT_MODE, publicKey);
            String encryptedData = Base64.encodeBase64String(cipher.doFinal(dataToBeEncrypted.getBytes()));
            System.out.println("Encrypted Data: " + encryptedData);

            Cipher dipher = Cipher.getInstance("RSA");

            dipher.init(Cipher.DECRYPT_MODE, key);
            System.out.println(new String(dipher.doFinal(Base64.decodeBase64(encryptedData))));

        }
    }
}

它工作正常，因为 'admin' 是在之后加密和解密的。但是当我复制这个加密值并想将它粘贴到我的 BAM 配置文件密码中时，ESB 无法获取它并且密码为空并且在控制台中我得到了这个：

Caused by: javax.xml.stream.XMLStreamException: ParseError at [row,col]:[1,429]
Message: An invalid XML character (Unicode: 0x2) was found in the element content of the document.
        at com.sun.org.apache.xerces.internal.impl.XMLStreamReaderImpl.next(XMLStreamReaderImpl.java:598)
        at com.sun.org.apache.xerces.internal.impl.XMLStreamReaderImpl.getElementText(XMLStreamReaderImpl.java:842)
        at org.apache.axiom.util.stax.wrapper.XMLStreamReaderWrapper.getElementText(XMLStreamReaderWrapper.java:100)
        at org.apache.axiom.om.impl.SwitchingWrapper.getElementText(SwitchingWrapper.java:962)

第二个问题是，当我尝试解密密码时（WSO2 ESB 通过导出 BAM 配置文件加密它，它是 'adminToDecrypted'）我得到这个：

Exception in thread "main" javax.crypto.BadPaddingException: Decryption error
    at sun.security.rsa.RSAPadding.unpadV15(RSAPadding.java:380)
    at sun.security.rsa.RSAPadding.unpad(RSAPadding.java:291)
    at com.sun.crypto.provider.RSACipher.doFinal(RSACipher.java:356)
    at com.sun.crypto.provider.RSACipher.engineDoFinal(RSACipher.java:382)
    at javax.crypto.Cipher.doFinal(Cipher.java:2087)
    at Main.main(Main.java:37)
    at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)

    at java.lang.reflect.Method.invoke(Method.java:606)
    at com.intellij.rt.execution.application.AppMain.main(AppMain.java:140)

所以，也许我做错了什么或者我错过了一些重要的事情。也许还有其他方法可以做到这一点。也许 WSO2 存储库中有一个 class，我可以在那里找到它是如何工作的？

更新

我注意到在我的代码中每次运行代码时我都会得到新的加密密码，但在 WSO2 ESB 中我总是得到相同的字符串。

Answer 1

当 encrypting/encoding 和 decoding/decrypting 时，请尝试以下操作：

org.wso2.carbon.core.util.CryptoUtil.getDefaultCryptoUtil().encryptAndBase64Encode(value.getBytes())

到decode/decrypt，使用方法：

base64DecodeAndDecrypt()

您必须为 org.wso2.carbon.core（或 org.wso2.carbon.utils 添加依赖项，尝试这两个）才能使其正常工作（检查您的 <product>/repository/components/plugins 以找到依赖项的正确版本）

我不确定这是否适用于您的情况，但大多数碳基产品都是这样做的。
