You know it's _proper_ vintage crypto code because it uses the now very unfashionable word 'encipher'.

Funny but also thought-provoking! When did the verb "encipher" give way to "encrypt," and why? I might enjoy reading a well-researched piece on that subject.

So basically encipher was never used in the context of the web. And the web is what made encrypt popular separate from encipher. It does look like maybe encipher was possibly going to take off but encrypt stepped on its head.

Interestingly, the basis of web encryption does use the term "encipherment" -- the `KeyUsage` field of X.509 certificates has `keyEncipherment` and `dataEncipherment` flags.
