Accessing Apigee Truststore and Keystore in the API Proxy

[#1]

Hi

I need to implement and develop some token encryption and validation inside my API Proxy. I can upload my private key and public key into Apigee keystore/trust store. However there is no policy (except the SAML Assertion Policy) to allow me to access the apigee Keystore/Truststore.

Is there any alternative solution around this? or can I upload my API Proxy bundle with the JKS and not use APIGEE JKS?

Thanks,

Reza
