Clearing secrets from memory #45
Description
Following on from #42 (comment)
I don't think this is enough to securely erase the secret from memory. I think what this is doing is that it's changing a pointer to point to the new Fr::zero(), and then lets rust reclaim the old Fr secret eventually.
lets log an issue and we can investigate a Zeroize impl in upstream blstrs
Let's be sure to revisit this.
