[jQuery] Question on encode/decode of JSON - server-side and client-side


I am building a client-side and server-side solution and want to use
JSON through Ajax in both directions.
I have ASP or JavaScript server-side, though Microsoft's support of
server-side JavaScript seems nil, so I am reluctantly conceeding to
use ASP.
I'd appreciate suggestions on available solutions to encode/decode
JSON on the server-side (ASP or JavaScript). I don't plan to load
jQuery server-side so that rules out plug-ins.
I'd also like to know what is the latest client-side encode/decode for
JSON. Is it built in jQuery or a plug-in?
In both server and client, decoding JSON securely is key, so using eval
() to decode is out.
Thanks,
Sam
