对VFP数据库更加可靠的加密算法

A More Reliable Encrypted Algorithm for VFP 5.0 DBF

当通过采用随机数生成密码时,密码无规律可寻,即使用户知道密码的生成算法,也很难破译。合法用户输入的密码可以通过解密算法被系统接受,用户可以根据使用要求改变密码,通过加密算法生成新的不可识别的密码存放到数据库中。

It creats password with random number, password is ruleless,eyen if users know encrypted algorithm, password will not have been deciphered, legal users' password is accepted by system through decrypting algorithm, they may modify their password, new password is saved into database by encrypted algorithm.
