Mike - thanks loads :-) I was trying to use the dictionary syntax:
*Syntax: * encrypt *source* using *cipher* with [password|key] *passorkey *[and salt saltvalue] [and IV *IVvalue*] [at *bitvalue* bit] I found your explanation much more friendly, in fact got it working first shot. We think alike - I already use Monte's mergEXT, excellent Man & stuff. Also plan on using the DropBox method for some things. Wanted to learn the native LiveCode version however, i like to go native whenever i can ;-) Is there a webpage for the DropBox REST api effort you refer to?
