How to protect private keys in server side? #fabric #fabric-sdk-java #fabric-ca

Hi all,

As I knew that in Fabric network, users' private keys are all stored in the backend servers, so that backend with SDK can generate transactions that signed as users.

And I knew we shouldn't store private keys into the ledgers.

"No one is going to store private key on the blockchain as all participating peer will hold copy of Private key"
Ref: https://lists.hyperledger.org/g/fabric/topic/26203197
But is there any solution for Fabric to protect private key storage in server side? or I shouldn't store the private key in the server as files?

Regards,
Hubert
