The prekey messages are signed with the owner's identity key.
- sehrope 13y agoAre the prekeys generated/saved per potential contact (signed/encrypted with the contact's public key of course!) or is it a general pool for everybody? If it's the latter than couldn't a malicious user flood you with 100+ messages and prevent others from async contacting you?
