有会java 单字节加密解密的吗 - Java / Java SE

能不能给点代码看看，非常感谢！

---

( ⊙ o ⊙ )啊！好复杂啊

---

我刚试了，这个也不错啊，还有其它好的加密解密方法吗

---

学习一下，还没研究过！

MD5+base64

Java code:

/**
*
*/
package com.dianruo.console.common;

import java.security.MessageDigest;

public class MD5 {
private final static String[] hexDigits = { "0", "1", "2", "3", "4", "5",
"6", "7", "8", "9", "a", "b", "c", "d", "e", "f" };

/**
* 转换字节数组为16进制字串
*
* @param b
* 字节数组
* @return 16进制字串
*/

public static String byteArrayToHexString(byte[] b) {
StringBuffer resultSb = new StringBuffer();
for (int i = 0; i < b.length; i++) {
resultSb.append(byteToHexString(b[i]));
}
return resultSb.toString();
}

private static String byteToHexString(byte b) {
int n = b;
if (n < 0) {
n = 256 + n;
}
int d1 = n / 16;
int d2 = n % 16;
return hexDigits[d1] + hexDigits[d2];
}

public static String MD5Encode(String origin) {
String resultString = null;

try {
