NSA posts encrypted tweet to recruit code breakers — RT News

NSA posts encrypted tweet to recruit code breakers — RT News





The National Security Agency has decided to kill two birds with one stone by advertising for potential code breakers in cipher.




Some initially thought it was gobbledygook, but it turns out a
very cryptic text from the NSA was not the product of a
four-legged feline run wild on a keyboard or a smart phone gone
rogue in an agent’s back pocket. Rather, the tweet bearing the
hashtag #MissionMonday was a direct appeal to potential NSA
analysts who had the chops to decode the encrypted message.


The missive, consisting of nine blocks of letters, all of which
contained 12 characters except the third and the last, ended up
being an example of a substitution cipher, by which units of
plaintext are replaced with ciphertext according to a regular
system.
