nuid.specs

Cross-platform public specs common across NuID APIs.

Requirements

jvm, clj

Notes:

By isolating nuid.specs, we trade-off localization for generality: each spec in nuid.specs exists independently of (and removed from) context so that it may be required and applied anywhere without risk of circular dependency.

These specs will update as needed to reflect API changes. Many of the specs have been designed to benefit from the changes coming to spec to disambiguate schema and selection. This library exists as early groundwork in adding arbitrarily powerful, programmatically actionable rigor to public NuID APIs.

From Clojure and ClojureScript

clojure.spec is available to both Clojure and ClojureScript, so this library can be used from either.

tools.deps:

{nuid/specs {:git/url "https://github.com/nuid/specs" :sha "..."}}

usage:

$ clj
=> (require '[clojure.spec.alpha :as s])
=> (require '[nuid.specs :as specs])

=> (s/valid? ::specs/protocol {:id :knizk}) ;; => true
=> (s/valid? ::specs/protocol {:id :bad})   ;; => false

=> (s/valid? ::specs/credential
     {:protocol {:id :knizk}
      :curve {:id :secp256k1}
      :keyfn {...} ;; e.g. nuid.cryptography/generate-scrypt-parameters
      :hashfn {:id :sha256 :normalization-form "NFKC"}}) ;; => true

notes:

This library is still in the alpha phase of describing the shape of the data that flows between prover and verifier (as well as between more specific components in the system). More use and additional consumers will help improve and anneal these specifications.

It is important to remember that this library only ever describes ("specifies") pure data. E.g. nuid.specs/hashfn describes a data format that can be used by nuid.cryptography/generate-hashfn to produce an actual function for hashing values. It is helpful to mentally append -spec to the s/def's described in nuid.specs, which in practice would be annoyingly redundant.
