Give a real usage example of using crypt

also note, if you're a vi user you can use the following to edit the encrypted file:

vi -x encrypted.file

it prompts for the key just before clearing the screen and showing the contents
and of course, if the key you entered is wrong, you see junk ;)

For instance, if I have a file called foo.:

user1>$ ls -la
total 6
drwxr-xr-x   2 user1 staff      512 Aug 25 11:35 .
drwxr-xr-x  11 user1 staff      512 Aug 25 11:35 ..
-rw-r--r--   1 user1 staff      141 Aug 25 11:35 foo

show the steps that would be taken to encrypt this file.  Or better yet, create the file on your system, perform the steps for encryption, then cut and past your steps as your answer.  This is what was meant as a "real example".

Thanks.

crypt mykey   < foo  > foo.encrypted; mv foo.encrypted foo

CRYPT AN ASCII FILE

An ascii file can be easily encrypted and
decrypted.

To encrypt simply pipe the STDOUT of
the file to "crypt" and redirect it to
a new file name. Enter a passowrd when
prompted with "Enter key".

$ cat foo | crypt > foo.e
Enter key:

To unencrypt simply pipe the STDOUT of
the encrypted file to "crpyt" and
redirect it to a new file name. Enter
a passowrd when prompted with
"Enter key".

$ cat foo.e | crypt > foo.new
Enter key:

or use vi -x to view the file
$ vi -x foo.e
Enter key:
