The cryptographic primitives (ECDSA and HMAC) implementations in this package have been reviewed on the upstream repository, no changes have been done since then, however, more audits and reviews are welcomed.
The bitgreen.crypto.Random namespace contains a single function, named getRandomBuffer(size) that returns a Buffer instance with random bytes. It may not work depending on the engine that Bitgreen is running on (doesn't work with IE versions lesser than 11).
The bitgreen.crypto.BN class contains a wrapper around bn.js, the bignum library used internally in Bitgreen.
The bitgreen.crypto.Point class contains a wrapper around the class Point of elliptic.js, the elliptic curve library used internally in Bitgreen.
The bitgreen.crypto.Hash namespace contains a set of hashes and utilities. These are either the native crypto hash functions from node.js or their respective browser shims as provided by the browserify library.
bitgreen.crypto.ECDSA contains a pure JavaScript implementation of the elliptic curve DSA signature scheme based on elliptic.js.
