Hi,
Is there a way of executing encrypted files? I have encrpyted files using vi and crypt, but when I execute the encrypted file, it takes the contents literally (special characters, junk - encrpyted format).
Kind Regards,

Hi.
I want to execute a script when it's encrypted with "crypt".
I tried with "sh <script_crypted>", but it's incorrect because the commands into "script" can not be executed because they are encrypted.

crypt
crypt(1) crypt(1)
NAME
crypt - encode or decode a file
SYNOPSIS
crypt [password]
The crypt utility encrypts and decrypts the contents of a file. crypt reads from the standard input and writes on the standard output. The
password is a key that selects a particular transformation. If no password is given, crypt demands a key from the terminal and turns off
printing while the key is being typed in. crypt encrypts and decrypts with the same key:
example% crypt key < clear.file > encrypted.file
example% crypt key < encrypted.file | pr
prints the contents of clear.file.
Files encrypted by crypt are compatible with those treated by the editors ed(1), ex(1), and vi(1) in encryption mode.
The security of encrypted files depends on three factors: the fundamental method must be hard to solve; direct search of the key space
must be infeasible; "sneak paths" by which keys or cleartext can become visible must be minimized.
crypt implements a one-rotor machine designed along the lines of the German Enigma, but with a 256-element rotor. Methods of attack on
such machines are widely known, thus crypt provides minimal security.
The transformation of a key into the internal settings of the machine is deliberately designed to be expensive, that is, to take a substan-
tial fraction of a second to compute. However, if keys are restricted to (say) three lower-case letters, then encrypted files can be read
by expending only a substantial fraction of five minutes of machine time.
Since the key is an argument to the crypt command, it is potentially visible to users executing ps(1) or a derivative command. To minimize
this possibility, crypt takes care to destroy any record of the key immediately upon entry. No doubt the choice of keys and key security
are the most vulnerable aspect of crypt.
