Data.Signable

Digital signature is common security-related practice. One of the main difficulties of digital signature usage is necessity of determenistic data serialization agreement. This library provides Signable class which represents the idea of such agreement. Also worth mentioning generic proto-lens compatible implementation of serialization/signing algorithm described here. It's implemented as separate protoc plugin signable-haskell-protoc which generates Signable class instances for given proto-lens messages and enums.
