eccrypto: Elliptic Curve Cryptography for Haskell

This is a package candidate release! Here you can preview how this package release will appear once published to the main package index (which can be accomplished via the 'maintain' link below). Please note that once a package has been published to the main package index it cannot be undone! Please consult the package uploading documentation for more information.



Elliptic Curve Cryptography in Haskell, evolved for correctness and practical usability from higher-level libraries.

The implementation is pure Haskell and as generic and fast as reasonably possible. Timing-attack resistance is important, failure must be documented.

This library was formerly known and its code originated as hecc, but since this would imply Hyperelliptic ECC, the name was changed.

Also the scope was changed by selecting best internal formats and no longer trying to be overly general, allowing more optimizations.

Readme for eccrypto-0.1.0

[back to package description]
RSA just doesn't cut it anymore for fast public-key crypto. Keys are large for reasonable security making it quite slow...
Enter elliptic curves: smaller numbers are necessary and everything is faster. Maybe this library is not for embedded system usage, but now people can experiment with ECC for those use-cases where some form of RSA would be chosen otherwise.

This is a side-project from which other people may benefit. Due to time-constraints, I can't work as much on it as I would like. If you use/like it or want to make some criticism heard, please write an email.
