Hi
I have a use-case in which an XML like the following needs to be created. There are 2 elements, of which the second one is Mpin, this is an RSA encrypted value. To do this, I can write a JCN but is there a better (in built way?).
1. Can the certificates in the broker KeyStore be accessed programmatically in a JCN to avoid managing the certificates separately?
2. Is there any other way to do this without writing a JCN?
This is not a SOAP message , this is an XML payload sent over HTTPS.

Hi
So I gave this a shot with custom code in JCN, I am now at a stage where I need to read the private key from the brokers keystore to decrypt the incoming field. I can access the location of the brokers key store using the CMP , but I am unable to figure out how do I open the keystore and get hold of the key as both have passwords.
Any suggestions on how I can proceed with using the standard broker keystore, instead of doing file operations in my JCN ?
Regards
Akhilesh

Have you thought about setting up a SOAP service passing it the XML? Could you then use wss to decrypt it?
Have fun

Hi
Do you mean a flow like as follows
Flow 1 (that will send the encrypted element mPIN):
HTTPInput --> SoapRequest
Flow 2 (created to decrypt the element)
SoapInput --> ...
I thought about it, but wasn't too sure if something that's usually, done. I can try it for sure, I prefer using built in nodes as much as possible..but some specs like these are dictated by folks who don't really care much about standard..
I also went through the CMP documents & the Plugin JavaDoc, but did not find any information that could tell me if I could just get the loaded private keys..
Regards
Akhilesh
