关于旺龙梯控数据的研究

fsjt7910

问大家一个问题，下面这个数据是旺龙梯控的数据，该系统是一卡一密的，我也清楚
1-4扇区的数据部分全是FF，且每个扇区的秘钥也不一样
但是软件分析，旺龙梯控数据在5-7扇区，这个我修改也成功，也可以正常用
但是为什么1-4扇区的数据我全都恢复成00，秘钥也变成默认的FF，在电梯上就无法使用了呢？
难不成1-4扇区的数据也负责着旺龙梯控的什么功能吗？

確定用的是旺龍？

確定用的是旺龍？

确定电梯用的就是旺龙的系统，因为同楼里的有的业主卡1--4扇区就没有数据，多数的都有，所以我才搞不明白喆1-4扇区里的这些FF和加密不一样倒地是不是也参与旺龙系统的工作了，如果没参与，那为什么我删掉就无法刷卡使用了

我也在网上搜寻了不少地方的旺龙系统，有的里面也出现过用其他字符填满的情况，加密秘钥但是和旺龙系统是一样的

你的日期是：2022年6月30的

到期时间我知道，这个肯定需要改时间的，我是想了解1-4扇区这些FF和加密是否和旺龙系统有关，我想把其他的几部电器也写到这张卡里，但是数据占位冲突了，才是这删掉这些FF数据发现的就不能用了

常理同樓棟數據格式應該相同，不應該有區別

按理说是这个意思，可是确实就出现了不同的数据格式，也都能正常使用，所以我这才搞不明白这到底是为什么哪里出的问题

学习学习，研究就会进步

好像是呀，如果这样的话，旺龙要实现软发卡，就成为了特别头疼的问题了。

确实是个问题，我也问了很多会算法会写软件的人，他们也都是卡密怎么计算不会，或者会也不教给，哪怕是怀谦学习旺龙的卡密算法，也都不肯教，具体不清楚为什么，还有就是我文中写的，1-4扇区的这些，到底有什么作用，删了就不能用了，如果原卡没有这些的，加入FF倒不会影响很是奇怪

是呢？密码是怎么算出来的呢？
