VI help

[Riyaz]

Hi Admins,
I have encrypted a file using vi -x filename option. Now I have
lost the encryption key to open the file. Is there any way I can
retrieve the data from the crypt file.

Well, there is no such option in /my/ vi, nvi. So I'll guess you're
using vim. A quick google gave me this: From the vim documentation:

<quote>
- There is never 100% safety. The encryption in Vim has not been tested for
robustness.
- The algorithm used is breakable. A 4 character key in about one hour, a 6
character key in one day (on a Pentium 133 PC). This requires that you know
some text that must appear in the file. An expert can break it for any key.
- Pkzip uses the same encryption, and US Govt has no objection to its export.
Pkzip's public file APPNOTE.TXT describes this algorithm in detail.

IE this far you could've come with a simple bit of RTFM.

standard vi has an encryption option, but vim's algorithm is unrelated to it.
