java密码加密

MD5加密：

加密后的结果为：

try {String password = vo.getPassword();MessageDigest md = MessageDigest.getInstance("md5");byte[] bytes = md.digest(password.getBytes());String str = Base64.getEncoder().encodeToString(bytes);vo.setPassword(str);} catch (NoSuchAlgorithmException e) {e.printStackTrace();}

SHA加密(安全性更高) 

try {String password = vo.getPassword();MessageDigest md = MessageDigest.getInstance("SHA");md.update(password.getBytes());String str = new BigInteger(md.digest()).toString(32);vo.setPassword(str);System.out.println(str);} catch (NoSuchAlgorithmException e) {e.printStackTrace();}
