Hi Galen,
This thread may be of interest…
As an aside I used this javascript library to decrypt variables in a client form as required. Hence they are obfuscated if you look at the variables in cockpit etc. I used key based encryption where the key was either the process ID or the business key. Whilst this keeps prying eyes off the data, its really just obfuscation as the key was a process variable and thus not really secure…
I support your feature request, encrypted process variables as part of the core engine would be a nice feature at times…
regards
Rob
