我正在开发一个使用Java服务加密我从Web服务收到的签名的项目。我需要用JavaScript替换这段代码。
以下是我使用JavaScript http://jsfiddle.net/cDeyv/4/的地方（由于Rasmus Faber的帮助，代码现在可以正常运行）
这是Java
import java.io.ByteArrayOutputStream;
import java.text.SimpleDateFormat;
import java.util.StringTokenizer;
import javax.crypto.Cipher;
import javax.crypto.SecretKey;
import javax.crypto.spec.IvParameterSpec;
import javax.crypto.spec.SecretKeySpec;
// TODO: Auto-generated Javadoc
/**
* The Class SymmetricEncryption.
*/
public class SymmetricEncryption {
public static void main(String args[]) {
String signatureKey = "185-188-32-81-185-2-188-103-248-127-38-173-109-200-56-32-81-47-234-4-191-157-26-247";
String serverTime = "2011-01-12 18:48:43.000";
String encryptedSignatureKey = "240-230-243-218-251-103-145-3-156-109-41-25-127-185-149-150-36-96-176-154-83-24-20-89";
SymmetricEncryption sE = new SymmetricEncryption();
String result1 = sE.genericencrypt(serverTime, signatureKey);
System.out.println(result1);
}
/**
* The d format.
*/
public final SimpleDateFormat dFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
/**
* The ivbytes.
*/
public byte[] ivbytes = new byte[]{(byte) 0x00, (byte) 0x00, (byte) 0x00, (byte) 0x00, (byte) 0x00, (byte) 0x00, (byte) 0x00, (byte) 0x00};
/**
* The iv.
*/
public IvParameterSpec iv = new IvParameterSpec(ivbytes);
/**
* Genericencrypt.
*
* @param source the source
* @param keyString the key string
* @return the string
*/
public String genericencrypt(String source, String keyString) {
try {
// Generate key
SecretKey key = getKey(keyString);
// Create the cipher
Cipher desCipher = Cipher.getInstance("DESede/CBC/PKCS5Padding");
// Initialize the cipher for encryption
desCipher.init(Cipher.ENCRYPT_MODE, key, iv);
// Our cleartext as bytes
byte[] cleartext = source.getBytes();
System.out.println("Server Time ASCII " + new String(cleartext));
// Encrypt the cleartext
byte[] ciphertext = desCipher.doFinal(cleartext);
System.out.println("ciphertext ASCII " + new String(ciphertext));
// Return a String representation of the cipher text
return getString(ciphertext);
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
/**
* Gets the key.
*
* @param keyString the key string
* @return the key
*/
private SecretKey getKey(String keyString) {
try {
byte[] bytes = getBytes(keyString);
return new SecretKeySpec(bytes, "DESede");
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
/**
* Gets the string.
*
* @param bytes the bytes
* @return the string
*/
public String getString(byte[] bytes) {
StringBuffer sb = new StringBuffer();
for (int i = 0; i < bytes.length; i++) {
byte b = bytes[i];
sb.append((int) (0x00FF & b));
if (i + 1 < bytes.length) {
sb.append("-");
}
}
return sb.toString();
}
/**
* Gets the bytes.
*
* @param str the str
* @return the bytes
*/
public byte[] getBytes(String str) {
ByteArrayOutputStream bos = new ByteArrayOutputStream();
StringTokenizer st = new StringTokenizer(str, "-", false);
while (st.hasMoreTokens()) {
int i = Integer.parseInt(st.nextToken());
bos.write((byte) i);
}
return bos.toByteArray();
}
}
这是返回“240-230-243-218-251-103-145-3-156-109-41-25-127-185-149-150-36-96-176-154-83-24 -20-89"
我需要找到DESede / CBC / PKCS5Padding加密算法的实现。
对此有任何帮助将不胜感激。
