【Cypher】Room1 隐写术(上半)
Room1:Steganography (隐写术)
此房间一共有8个谜题请根据题目给出猜测得到的信息


STEGANOGRAPHY
Stegenography (concealed writing)is a form of cryptography whereby a secret message is hidden within another innocuous looking message,with the hope that it will pass undetected
Steganography is a weak form of cryotography as the secret message is not enciphered and relies entirely on its ability to go unnoticed.Once a hidden message is suspected it can usually be revealed without the need of any special techniques, given enough time and scrutiny.
When cryptanalysing a text you should begin by looking closely for any unusual aspects of the text such as alignment,spacing,word choice,etc, which Indicates the text has been forced into some pattem.Secondly you should look for altemate ways of interpreting the message aside from the obvious.
隐写术
隐写术(隐写)是一种密码学,其中一个秘密信息隐藏在另一个看起来无害的信息中,希望它能不被发现地通过
隐写术是比较weak的一种方式,因为秘密信息没有被加密,完全依赖于它不被发现的能力。一旦怀疑有隐藏的信息,只要有足够的时间和仔细的审查,通常不需要任何特殊的技术就能把它暴露出来。
当对文本进行密码分析时,您应该首先仔细检查文本的任何不寻常方面,如对齐、间距、单词选择等,这表明文本已被迫进入某种模式。其次,除了显而易见的信息,你应该寻找其他解释信息的方法。
谜题一:

以下是解法:

观察每句话的首字母,可得:spysuspected
谜题二:

以下是解法:
(这段文字来自艾伦-坡的一首诗'The Raven' )
Once upon a midnight dreary, while I pondered, weak and weary
Over many a quaint and curious volume of forgotten lore
While I nodded, nearly napping, suddenly there came a tapping
As of some one rapping, rapping at my chamber door
"'Tis some visitor," I muttered, "tapping at my chamber door--
Only this, and nothing more."
经过对比,可以看出有几个单词拼写是错误的,是
while forgotten suddenly door muttered chamber
whille foregotten suddenly dooor mutterred chambere

多出来的字母合成一个单词:lenore
(这题设计得很巧妙呀!lenore是爱伦坡《Lenore》中的已逝少女,是爱伦坡已逝娇妻弗吉尼亚的化身,《The Raven》(乌鸦)中的已逝少女。)
谜题三:

以下是解法:

凑近放大了看...有很淡很淡的字迹......(😀)
谜题四:

以下是解法:
仔细观察文字,可以看出有些文字区分与其它文字(斜体),找出来发现是:
too one for free
利用读音,too和two同音,for和four同音,free发音相近于three
所以可以得出:“2 1 4 3”
