How to Generate Sign a JSON Payload using RSA Key and SHA256 Algorithm In OIC

Summary:

Hi All,

I have a requirement to generate signature for the json payload using RSA private key using SHA256 algorithm.

After generating the signature I need to add additional JSON field with signature value and send to external system and I need to implement this using OIC.

Is there any external XSLT function or any library available to generate this requirement

E.g

{

{ << Request Paylaod>>

},

"SignatureValue":"BASE64 ENCODED RSA Signature of the payload"

}
