WSO2使用公钥 - 私钥加密/解密密码(字符串)

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公钥我可以加密/解密密码,所以我写这个:

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'经过加密和解密。但是当我复制这个加密值并希望将其粘贴到我的BAM profle密码中时,ESB无法获取它并且密码为空,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(WSO2 ESB通过导出BAM配置文件加密它,并且它是'adminToDecrypted')时,我得到了这个:

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 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。也许有其他方法可以做到这一点。也许在WSO2回购中有一个类我可以找到它是如何工作的?

更新

我注意到在我的代码中,每次运行代码时都会获得新的加密密码,但在WSO2 ESB中,我总是得到相同的字符串。

1 个答案:

答案 0 :(得分:1)

加密/编码和解码/解密时,请尝试以下操作:

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

要解码/解密,请使用以下方法:

base64DecodeAndDecrypt()

您必须为org.wso2.carbon.core(或org.wso2.carbon.utils,尝试这两种方法)添加一个依赖项才能使其正常工作(检查您的<product>/repository/components/plugins以找到正确的依赖的版本)

我不确定这是否适用于您的情况,但这是大多数碳基产品的完成方式。
