INTRODUCTION TOCRYPTOGRAPHY

Cryptography is the study of secret messages.

Cryptography has been used throughout history as a means ofexchanging private correspondence such as personal letters,important military communications and financial information.

This has created an ongoing race between cryptographers whodesign increasingly complex ciphers and the cryptanalysts whoattempt to crack them.

The six chambers ahead present a series of puzzles designed tointroduce you to some of the most common ciphers, andtechniques for breaking them. They are arranged roughly in orderof complexity.

Cryptanalysis can be a time consuming task requiring patienceand focus. The puzzles ahead are largely left to your creativity tosolve, but all the clues needed are present within the rooms.

So grab a pen and paper and good luck!

密码学入门（机翻

密码学是对秘密消息的研究。

密码学在历史上一直被用作交换私人信件（如私人信件，重要的军事通信和金融信息）的手段。

这在设计越来越复杂的密码的密码学家和试图破解密码的密码分析师之间造成了一场持续的竞争。

前面的六个房间展示了一系列谜题，旨在引导您找到一些最常见的密码，以及破解它们的技术。它们大致按复杂程度的顺序排列。

密码分析可能是一项耗时的任务，需要耐心和专注。前面的谜题很大程度上留给你的创造力来解决，但所有需要的线索都存在于房间里。

所以拿起笔和纸，祝你好运！
