An iron mask and an uncrackable code...

I’ll probably never get tired of writing blog posts about cryptography. It’s a puzzly skill with plenty of real-world applications. Heck, England hosts a yearly codebreaking challenge in order to identify people with topnotch cryptographic abilities in the hopes of recruiting them for government work! 417 more words
