2 @section Verifier structure
4 Verifier is a derivative of the password. It is resistant to
5 dictionary attacks and can not be used for authentication (only
9 SOURCE = Balloon(PASSWORD, SALT=PeerId, sCost, tCost, pJobs)
10 PUB, PRIV = Ed25519.Generate(SOURCE)
13 Balloon hashing uses BLAKE2b-256 hash. Space cost (sCost), time cost
14 (tCost) and number of parallel jobs (pJobs) are specific to Balloon
17 Verifier is serialized representation of public data above:
19 $balloon$s=s,t=t,p=p$Base64(SALT)$Base64(PUB)
22 Server stores and knows only verifier. Client can compute the whole
23 keypair every time he makes handshake.
