说明：  delphi字符串加密,可以将delphi源代码中的字符串作加密处理，发布程序前可以用。虽然加密算法简单，但因为密码是随机生成的，所以还是可以起到一定的保护作用的。
(delphi string encryption, can be delphi source code of the string for encryption processing, pre-release procedure can be used. Although the encryption algorithm is simple, but because the password is randomly generated, it can still play a protective role.)
