In Hyperledger Fabric, what is used if end users of the application want to keep their private key secret?

Show Suggested Answer Hide Answer
Suggested Answer: A

In Hyperledger Fabric, if end users of the application want to keep their private key secret and secure, they would use offline signing. Offline signing involves signing transactions on a device or in an environment that is not connected to the network or the internet. This method ensures that the private key used for signing does not get exposed to the network and reduces the risk of compromise. Offline signing is especially important in scenarios where security and privacy are paramount, as it allows users to maintain control over their private keys at all times.

I thought online signing could work too, but maybe not for privacy?

I practiced a similar question, and I think offline signing was the answer, but I hope I’m not mixing it up with something else!

I definitely remember that shared signing was mentioned, but it seems more about collaboration than keeping keys private.

I feel like we discussed online signing in class, but I can't recall if it's the right choice for keeping keys secret.
