Dear Haskell Community! It was a long~ish time ago I released hecc[1], which had an unfortunate but funny (to me) name, later together with hF2[2]. Since I have neither released hyperelliptic curve crypto support, nor my pairing based crypto, a generalising change in names would be in order. Today I am releasing eccrypto[3], which contains the code of both (to allow easier refactoring of new ideas) and something new: A pure Haskell, timing-attack resistant Ed25519[4] implementation! ...well, a very rough one at least. The code is not "done", gives wrong results, is _very_ slow, but it might serve as reading material as well as a primer what I plan to do in the future. I do not plan to add embedded C or assembler code, but plan to make the code comparatively fast to some common implementations as well as timing attack resistant (see: [5]), even if it will never be as fast as the best code used in contemporary benchmarks. Sadly, due to health issues, I am not able to work on said code and have not been for a time longer than I care to admit. All comments are welcome, but I will not be able to guarantee answers. ;) Best of wishes to a thriving community, Marcel Fourné [1]: https://hackage.haskell.org/package/hecc [2]: https://hackage.haskell.org/package/hF2 [3]: https://hackage.haskell.org/package/eccrypto [4]: https://ed25519.cr.yp.to/ [5]: https://mail.haskell.org/pipermail/haskell-cafe/2015-February/118213.html
