hs-ed25519's Introduction

Minimal package for ed25519 signatures

This package implements minimal bindings to the ed25519 signature scheme. It's designed to be small, with no dependencies, and fast. It also comes with extensive guidelines and detailed documentation. It should be relatively easy to both depend on directly with Cabal or even copy into any projects that need it directly.

For full details (including notes on the underlying implementation), check out the docs.

Installation

It's just a cabal install away on Hackage:

$ cabal install ed25519

Needs update for QuickCheck 2.7

Hi,

I’m getting build failures on Debian:

Preprocessing test suite 'properties' for ed25519-0.0.2.0...

It seems that you need to upgrade to the latest QuickCheck.

[Question] load secretkey from a file

Hello,
I created Keypair (pk,sk) and I saved sk in a file.
How I can rehydratate sk?
Sorry if it's a noov question

Test & add support for GHC 8.0

cope with QuickCheck >= 2.12

tests/properties.hs needs 5 underscores after Success n, 5 underscores after GaveUp n, and 12 underscores after Failure n for QuickCheck 2.12 and 2.13.

Support calculating public key from private key

This is crypto_sign_publickey() which is missing at the moment.

Test suite failure with GHC 8

This is due to hlint failing, I'm not sure if it's related to GHC 8:

Support for deserializing PublicKey and Signature

I'm building a server where I need to send signatures and public keys back and forth, in order for the client and server to verify each other's messages. I can send both PublicKeys and Signatures as ByteStrings using unPublicKey and unSignature, respectively, but I cannot construct the original objects back from this serialization, as far as I can see.

Please adjust version bound of ghc-prim for GHC 8.10 compat

For GHC 8.10 the version bound of ghc-prim needs to be:

ghc-prim    >= 0.1 && < 0.7
