比尔密码
梦想自己能得到一张藏宝地图，上演一段破译密码探寻宝藏的传奇故事？你的机会来了。据说，在 1820 年，一个叫做托马斯·杰斐逊·比尔（Thomas Jefferson Beale）的人在弗吉尼亚贝德福县的某个地方埋藏了大量的宝藏，随后把装有三封密信的盒子交给了一个名叫罗伯特·莫里斯（Robert Morriss）的旅店老板代为保管，之后就永久地消失了。莫里斯死前把盒子里的三份密文交给了他的朋友。这位朋友把这段故事连同密码全文一道印成了小册子，宝藏之谜就这样流传了下来。

利用《独立宣言》作为密钥，可以破解出第二份密码。第二份密码中详细记录了所藏宝藏的数量，现在看来至少值 6500 万美金。这份密文中还说到，宝藏的埋藏地点详细地记在了第一份密码内，而第三份密码里则记录着宝藏的原主人。虽然各方神圣都把五花八门的手段试了个遍，但到目前为止，剩下的两份密码都还没被破解。不过，也有一些人对整个故事进行了理性的分析，认为比尔密码不过是一场骗局。
