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
