[comp.emacs] find,save-file w/ encryption

pezely@cis.udel.edu (Cowboy Dan) (02/10/91)

For those of us who are paranoid and/or suffer from network facism:  

Is there an encryption version of find-file and save-file such that you can
associate a key with a buffer so that the disk version of the file is
encrypted but the buffer version is plain-text?

thanks,

A quick response from David C Lawrence <tale@turing.cs.rpi.edu>:
ftp tut.cis.ohio-state.edu 
and look for crypt.el in pub/gnu/emacs/elisp-archives/misc/.

It works, but by doing only what's in the directions in the file, only the
saved files are encrypted via crypt: the auto-save files are not
encrypted.  I haven't had time to look into it yet, so maybe it does take
care of that also.  

Since this uses Unix crypt(1), and some sites don't have that some people
may have problems.  Assuming you do have it, you can read previously
encrypted files (ie, the lisp stuff doesn't do anything wacky).

Thanks,
