Fortunately I remembered that I had already written all this symmetric
encryption stuff in a separate project, so I just cut and paste a bit.

(I mean, the encryption primitives are already in Emacs, but actually
using them requires a bit of typing...)

(auth-source-search :max 1 :host "foo.bar")
=> ((:host "foo.bar" :user "zot" :secret #[0 "..." 
["Ng==-26GRPWrYlJnQAE+8gaEDcg==-DThpcRwaAi5ZBXQZC0rC3g==" (nil) 
auth-source--deobfuscate] 3]))

There.  That's better.  It does leak that the password is 6 characters
long, though, but that's a lot less leaky than ... it was before.
