Encrypt & Decrypt specific parts of your JSON using GatewayScript

If you're using IBM DataPower Gateway and need to asymmetric encrypt or decrypt just a part of a json object, it might be complicated. This two GatewayScripts will assist you doing that with a minimal effort.

How to use it?

Just drop them on your processing rule, configure the relevant parameters and you're good to go.
