Hmm mine too, never noticed that. Unfortunately it's weak encryption,
(apparently the same algorithm used by Pkzip) and pretty much useless.

Too bad. :-\ Fwiw, checked in the man page for our `ed' and I guess it
still supports this, and with reasonably strong crypto:
x Prompts for an encryption key which is used in subsequent reads and
writes. If a newline alone is entered as the key, then encryption
is turned off. Otherwise, echoing is disabled while a key is read.
Encryption/decryption is done using the bdes(1) algorithm.
I don't think I'll be making a habit out of using line editors anytime
soon though. ;P
