protect's Issues

Cannot verify recovered signature

I used "com.ibm.pross.client.signing.RsaCertificateAuthorityClient" class to generate rsaSharing, store private key share on servers and sign message with "private BigInteger signMessage(final BigInteger toBeSigned)" method to get recoverd signature, but when I verified signature with SigningUtil.verifyDefault, it returned false.

Add unit tests

Not all classes have unit tests, and some unit tests are failing.

Add rekeying

Consider adding during each epoch change, having each shareholder send a rekey message over the channel to migrate the public key(s) used by a shareholder (signed by the previous private key). -- preventing the next refresh from being compromised.

README Instructions?

Hi Jason,

Just came across this repo; what is the current state of the implementation and can the README be updated to reflect any possible instructions for running things?

Many thanks,
Josh

Missing certificate generation script

Hi Jason,

I was following the tutorial and I got stuck when issuing client and server certificates. I could not find the following issue-server-certificates.sh, issue-client-certificates.sh scripts. Could you provide me with some instructions on how to create those by myself?

Thank you.
