script encryption

hi all ,
i have a script that is written in ksh ,
i was wondering if there is a method or a command that can be used to encrypt the script and still make it execuable .
i am running solaris 9 on SPARC .
thanks

See this thread.

Perhaps consider using gzexe. It prevents casual browsing of a script, but does not encrypt.

A shell obfuscator:
