字符加解密
'**************************************************'函数ID：0041[生成随机密码]
'函数名：MakeRndPass
'作 用：生成随机密码
'参 数：passlen ---- 要生成的密码长度
'参 数：passtype ---- 要生成的密码类型
'返回值：验证生成的随机密码
'类型解释：
'passfull （所在可用字符如“90!@#$%”）
'passnumber （纯数字）
'passspecial （非常用字符）
'passCharNumber （所有字母及数字）
'passUpperCharNumber （大写字母数字）
'passLowerCharNumber （小写字母数字）
'passChar （所有大小写字母）
'passUpperChar （所有大写字母）
'passLowerChar （所有小写字母）
'示例：MakeRndPass(4,"passUpperCharNumber")
