Cryptography.ECDSA (secp256k1 only)
This is an easy-to-use implementation of ECDSA cryptography (Elliptic Curve Digital Signature Algorithm), implemented in C#, released under the MIT license. With this library you can quickly sign transactions.
This library implements transaction signing based on secp256k1 algorithm which is used in Graphene-based blockchains such as Steem and Golos. The library is based on https://github.com/warner/python-ecdsa No other curves are included.
The project contains several classes and structs. Almost all of them are internal (hidden), including PrivateKey and PublicKey. You may use public classes Secp256K1 and Base58 for signing or make some other classes public if needed.
More to come
We are taking the final steps to release first add-on for transaction broadcasting. In a few days we will make it open source as well. Stay tuned!
