Saving an unencrypted copy of a file encrypted with vi

Well I did something stupid. I opened a file using vi, and accidentally saved it using <esc>:Xx.
So I know the key is x, but what I can't figure out is how to save the file without encryption.

The last time I did this was in the 80's. and my memory is a bit hazy...

I think you need the crypt command. Write the file out, it will be encrypted and let's call the output ciphertext. Then run:
Code:
crypt < ciphertext > plaintext

I don't remember if crypt will prompt you for the key or if you pass it as a parameter. Give that a try and please let us know if it works.

The crypt command does work; the key is prompted for.
My other solution was to copy and paste the program file using the terminal emulator with two sessions open.
