Documentation

Overview

Package bbsblssignature2020 implements the BBS+ Signature Suite 2020 signature suite (https://w3c-ccg.github.io/ldp-bbs2020) in conjunction with the signing and verification algorithms of the Linked Data Proofs. It uses the RDF Dataset Normalization Algorithm to transform the input document into its canonical form. It uses SHA-256 [RFC6234] as the statement digest algorithm. It uses BBS+ signature algorithm (https://mattrglobal.github.io/bbs-signatures-spec/). It uses BLS12-381 pairing-friendly curve (https://tools.ietf.org/html/draft-irtf-cfrg-pairing-friendly-curves-03).
