工作中用到的加密算法。
/** * 加密網(wǎng)卡MAC地址 * * @param mac 網(wǎng)卡MAC地址 * @return 加密后的網(wǎng)卡MAC地址 */ public static String encryptMac(String mac) { StringBuffer buffer = new StringBuffer(); String[] segments = mac.split("-"); Random random = new Random(); for (String segment : segments) { buffer.append("-"); for (int i = 0; i < segment.length(); i++) { int rand = random.nextInt(10); buffer.append((char)('A' + rand)); int initValue = String2Integer(segment.substring(i, i + 1), 16); initValue ^= rand; buffer.append((char)('A' + initValue)); } } return buffer.length() > 0 ? buffer.substring(1) : ""; } /** * 解密網(wǎng)卡MAC地址 * * @param encryptMac 加密后的網(wǎng)卡MAC地址 * @return 網(wǎng)卡MAC地址 */ private static String decryptMac(String encryptMac) { StringBuffer buffer = new StringBuffer(); String[] segments = encryptMac.split("-"); for (String segment : segments) { buffer.append("-"); for (int i = 0; i + 1 < segment.length(); i++) { int rand = segment.charAt(i) - 'A'; int next = segment.charAt(++i) - 'A'; int originVal = next ^ rand; buffer.append(Integer.toHexString(originVal)); } } System.out.println(buffer); return buffer.length() > 0 ? buffer.substring(1) : ""; } 加密方法測(cè)試：decrpyt("00-21-9b-3d-29-0c") 解密方法測(cè)試：不解釋 |
