I’m trying to write a customization in Lyris ListManager (10.2). The language is TCL, which I know very little about. We need to encode a value as base64 (or really, anything that obfuscates a querystring parameter), but I can’t seem to figure out how. Is there a command native to TCL to do this?

    Following your problem to use the base64 package you can use these little procs to convert your data to hex and back. Requires Tcl > 8

    proc BIN2HEX { text }   { binary scan $text H* result; return $result }
proc HEX2BIN { hex }    { return [binary format H* $hex] }
set hex [BIN2HEX $yourText]
set textAgain [HEX2BIN $hex]

    If you really need base64 you can just copy/paste the entire base64 file from the tcllib distribution http://sourceforge.net/projects/tcllib/files/tcllib/1.11.1/ into your code (remove the “package provides” line)
