@giovaneliberato - is this the one you're working on?

[giovaneliberato]

@olabini I finished the reading of prekeys. I'm thinking about started the other ones as things are fresh in my mind.

what do you thinki @claucece?

working on the prekey profile

Thanks @giovaneliberato I think the shared prekey does not make sense.. I'm putting this on the things to discuss on the next meeting.

[claucece]

@giovaneliberato I finished writing and reading the shared prekey. I guess the only thing missing here is to test the prekey profile reading.

@giovaneliberato I added the missing test for the prekey profile. We can close this now.
