Hi,

We have a requirement to encrypt and decrypt messages in IIB 10.
Can you please refer to any documentation or ideas around it ?

hi...you could write java to do the encryption/decryption or reuse one of the existing java modules which provides such functionality and call it from IIB.

Found an IIB plugin which deals with encryption/decryption but only supports RSA,

Can you elaborate on the requirement? There may be other approaches.

Are you looking at private key encryption or PKI ?

Key management is a big issue. The private keys or certificates must be very securely stored.

Java supports AES encryption, so you could build a wrapper library for IIB flows.

Hi,

We need to implement the AES-256 encryption and decryption.
I was trying to understand if there is a possibility to store the keys in keystore and retrive them with a label name.
One approach was to build a IIB node to encrypt and decrypt and have a property for label to pick the right certificate from keystore.

Please let me know if I am thinking in the right direction.

OK. What is the payload coming in & going out? MQ messages? Is the encryption / decryption confined to the broker, or will other external apps also be encrypting / decrypting payloads?. ie. Are you securing payloads within IIB, or across integration paths (eg. MQ, http, DB) ?

We need to encrypt a message from an internal system using AES 256 in IIB and send it to an external system using http REST Service. Decryption will happen in an external system outside our network.

When an external system sends an encrypted message, we need to decrypt the message and deliver to internal system again.

Is the security requirement for protection of data across the network? HTTPS would meet this requirement, and you wouldn't need to worry about private key management.
