thats mearly impossible to do without having atleast part of the script of yours that is encrypted.
you can user $encode(string,[m u]) to do it, and then $decode(string,[m u]) to decode it, respectively. the u switch uses Uuencode encoding, as the m switch uses mime encoding. these are very simple encryption algorithms though, and aren't being used nearly as much now because the ease of decoding them. it's really quite pointless to use them anymore actually.
some other common encryption algorithms may be used:
md5 - this is a 1 way encryption algorithm used forcomparison. it can be "cracked" however, it requires a brute force to do so, so it's very sexure, especially on a remote location.
blowfish - this is key encryption that can be specified to be either 1 way, or as an encoding/decoding algorithm. if this encryption is used, you will have to have a .dll file to use it. when used as "2 way" it requires a key (or password).
