java常见的密码加密方式base64 Sha256 MD5

java对密码常见的加密方式：

一、MD5

String password="123456";String salt = StaticConstant.SALT;new SimpleHash("MD5", password, salt, 1024).toHex()

二、Sha256

public static String getSha256(String str) {MessageDigest messageDigest = null;String encodeStr = "";try {messageDigest = MessageDigest.getInstance("SHA-256");messageDigest.update(str.getBytes("UTF-8"));encodeStr = byte2Hex(messageDigest.digest());} catch (Exception e) {System.out.println(e.getMessage());}return encodeStr;}
