The NSA recruiting Twitter account sent out a confusing message on Monday morning. While some thought the account had been hacked or a mess of typos had been actually tweeted, the message was actually a cryptogram:
周一早上,美国国家安全局的官方招募推特账号发布了一条让人不解的消息。有的人还以为是这个账号被黑客入侵或者是出现了乱糟糟的打字错误,但实际上这是一条密码:

— NSA (@NSACareers) May 5, 2017
For a pro, this is actually a relatively easy code to figure out. It translates to:
对于一个专业人士而言,这条密码其实挺容易解出,翻译过来就是:
"Want to know what it takes to work at NSA? Check back each Monday in May as we explore careers essential to protecting our nation."
“想知道怎样才能在美国国家安全局工作吗?记得5月的每个周一来看我们发布的消息,我们会带你探究那些对于保护我们国家至关重要的职位。”
The tweet is a substitution cipher, in which each letter is swapped for another. In the code, each 'word' is twelve letters long, unless there is punctuation. This suggests that the spaces in the tweet do not matter, only the letters determine the code. This is one of the oldest (and easiest to solve) cryptograms, a necessity to decipher for any potential NSA cryptographer. If you couldn't figure it out, global communications surveillance probably isn't a good career path for you.
