[MACTCL] Encrypting a file?

[Tom J. <tj...@ac...>]

Hello,
I'm writing a small script that has to write out some account info to 
the file system. What I want to know is, if there is a way that I can 
encrypt the data being written to the file and un-encrypt it  when I 
need to read it back in to my utility?

Thanks

tom
