我目前正在解決方案中使用Java加密密碼(在Jboss服務器中運行),然後發送到DataPower中的Data Power和de-crypt。我能夠用Java加密密碼。我在DataPower中沒有太多的知識。我已經得到了在datapower中解密的代碼,但不知道如何將密鑰發送給datapower。任何人都可以請幫助我。代碼如下, 加密代碼(Java) 封裝測試;在Java中加密,在數據電源中解密
import java.io.ByteArrayOutputStream;
import java.security.Key;
import java.util.ArrayList;
import javax.crypto.Cipher;
import javax.crypto.spec.IvParameterSpec;
import javax.crypto.spec.SecretKeySpec;
import sun.misc.BASE64Decoder;
import sun.misc.BASE64Encoder;
public class Test {
private static final String ALGO = "AES";
public static String encrypt(String data,String secretKey) throws Exception {
Key key = generateKey(secretKey);
byte[] ivAES = {(byte)0x22,(byte)0x22,(byte)0x22,(byte)0x22,(byte)0x22,(byte)0x22,(byte)0x22,(byte)0x22,(byte)0x22,(byte)0x22,(byte)0x22,(byte)0x22,(byte)0x22,(byte)0x22,(byte)0x22,(byte)0x22};
IvParameterSpec ivspec = new IvParameterSpec(ivAES);
Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
cipher.init(Cipher.ENCRYPT_MODE, key, ivspec);
byte[] encVal = cipher.doFinal(data.getBytes());
byte[] finalByte=copyBytes(encVal, ivAES);
String encryptedValue = new BASE64Encoder().encode(finalByte);
return encryptedValue;
}
public static String decrypt(String encryptedData,String secretKey) throws Exception {
Key key = generateKey(secretKey);
byte[] decordedValue = new BASE64Decoder().decodeBuffer(encryptedData);
ArrayList<byte[]> al = retreiveIv(decordedValue);
byte[] data = al.get(0);
byte[] iv = al.get(1);
Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
cipher.init(Cipher.DECRYPT_MODE, key, new IvParameterSpec(iv));
byte[] decValue = cipher.doFinal(data);
String decryptedValue = new String(decValue);
return decryptedValue;
}
private static Key generateKey(String secretKey) throws Exception {
Key key = new SecretKeySpec(secretKey.getBytes(), ALGO);
return key;
}
private static byte[] copyBytes(byte[] encVal, byte[] iv) throws Exception {
ByteArrayOutputStream os = new ByteArrayOutputStream();
os.write(iv);
os.write(encVal);
return os.toByteArray();
}
private static ArrayList<byte[]> retreiveIv(byte[] combineByte) {
ByteArrayOutputStream iv = new ByteArrayOutputStream(16);
ByteArrayOutputStream data = new ByteArrayOutputStream();
data.write(combineByte, combineByte.length - 16, 16);
iv.write(combineByte, 0, combineByte.length - 16);
ArrayList<byte[]> al = new ArrayList<byte[]>();
al.add(data.toByteArray());
al.add(iv.toByteArray());
return al;
}
public static void main(String[] args) throws Exception{
System.out.println(AESUtil.decrypt(AESUtil.encrypt("Hello", "AVH4TU8AC99dhL2l"), "AVH4TU8AC99dhL2l"));
}
}
解密(DataPower的)
<xsl:variable name="algorithm">http://www.w3.org/2001/04/xmlenc#aes128-cbc</xsl:variable>
<xsl:variable name="decryptOut"><xsl:value-of select="dp:decrypt-data($algorithm,'name:danadp',$valueToDecrypt)"/></xsl:variable>
Decrypted Value: <xsl:copy-of select="$decryptOut"/>
但是,我沒有得到如何共享密鑰對象到DataPower我們在Java代碼進行加密。
這將是偉大的,如果任何人都可以幫助我。
