MD5加密(JAVA&JS)
JAVA:
package mydemo; import java.security.MessageDigest; public class MD5Utils { /*** * * MD5加码 生成32位md5码 */ public static String string2MD5(String inStr) { MessageDigest md5 = null; try { md5 = MessageDigest.getInstance("MD5"); } catch (Exception e) { System.out.println(e.toString()); e.printStackTrace(); return ""; } char[] charArray = inStr.toCharArray(); byte[] byteArray = new byte[charArray.length]; for (int i = 0; i < charArray.length; i++) byteArray[i] = (byte) charArray[i]; byte[] md5Bytes = md5.digest(byteArray); StringBuffer hexValue = new StringBuffer(); for (int i = 0; i < md5Bytes.length; i++) { int val = ((int) md5Bytes[i]) & 0xff; if (val < 16) hexValue.append("0"); hexValue.append(Integer.toHexString(val)); } return hexValue.toString(); } // 测试主函数 public static void main(String args[]) { String s = new String("xjn"); System.out.println("原始:" + s); System.out.println("MD5后:" + string2MD5(s)); } }
