I need a tcl Coder

I have two tool command language scripts (tcl) that i need encrypting to protect. I need these encrypted scripts to work on an external program that runs tcl 8.5. I downloaded Active States TCL Dev Kit 21 free day trial and this worked until the script expired. I need someone who understands compiling to provide me a subscription free version that will work for the life of the macro I am running. thanks
