Description:
Ed25519 cryptographic signatures; documentation
This package provides a simple, portable implementation of the ed25519 public-key signature system. It also includes support for detached signatures. . The underlying implementation uses the ref10 implementation of ed25519 from SUPERCOP, and should be relatively fast. . This package provides the documentation for a library for the Haskell programming language. See http://www.haskell.org/ for more information on Haskell.
