math so stubborn that even governments just politely ask for the password instead.

means The process of scrambling information into an unreadable form so that only someone with the right key can turn it back into sense.

from From Greek 'kryptos,' meaning 'hidden' or 'secret' — the same root buried in 'crypt' (a hidden underground chamber) and 'cryptic.' Wrap it in the prefix 'en-' ('to put into') and you literally get 'to put into hiding.' The Greek 'kryptos' traces back to 'kryptein,' 'to conceal.' The 'encrypt' verb itself is a modern formation, blooming in the 20th century alongside the machines and ciphers that made hiding data a science.
