It includes a\ntest suite of over a thousand test vectors that cover every feature provided by\nthe library.\n\nThe library is open-source, and is written by Nayuki from the ground up. It is\ndesigned with portability and clarity in mind, and is rigorously verified for\ncorrectness and quality.\n\nMore details about features and design principles are on the main web page:\n[https://www.nayuki.io/page/bitcoin-cryptography-library](https://www.nayuki.io/page/bitcoin-cryptography-library)\n\n\nLicense\n-------\n\nCopyright © 2019 Project Nayuki.
