encode text file

I have a text file ( a script ). And I don't want anyone to read this file. How can I encode it?

you could try mcypher or gpg

Sorry.Can you explain more about mcypher/gpg ?
How can I use them ? And does they use on Sun Solaris ?

Thanks

You could read something general about cryptography and, for example, gpg official documentation:
http://en.wikipedia.org/wiki/Cryptography
http://en.wikipedia.org/wiki/GNU_Privacy_Guard
http://gnupg.org/

...or openssl: 'openssl enc -e -bf -in infile -out outfile'.

Or the good old (and quite weak) traditional Unix way:

Code:

$ crypt < clear-file > encrypted-file
Enter Key: ...

Hi Jlliagre

My text file is a script.After using "crypt" command, I can't run encoded script. Do you have another way ?

You didn't tell you wanted to execute the script when encrypted. This is quite a different requirement.

as long as your security is set up properly and you are the only person with root access, you don't need to encrypt the file... you just need to set permissions properly on it.
