# Bitcoin Crypto
|
|
The cryptographic primitives (ECDSA and HMAC) implementations in this package have been reviewed by the BitPay engineering team. More audits and reviews are welcomed.
|
|
|
|
## Random
|
|
The `bitcore.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 bitcore is running on (doesn't work with IE versions lesser than 11).
|
|
|
|
## BN
|
|
The `bitcore.Crypto.BN` class contains a wrapper around [bn.js](https://github.com/indutny/bn.js), the bignum library used internally in bitcore.
|
|
|
|
## Point
|
|
The `bitcore.Crypto.Point` class contains a wrapper around the class Point of [elliptic.js](https://github.com/indutny/elliptic), the elliptic curve library used internally in bitcore.
|
|
|
|
## Hash
|
|
The `bitcore.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.
|
|
|
|
## ECDSA
|
|
`bitcore.Crypto.ECDSA` contains a pure JavaScript implementation of the elliptic curve DSA signature scheme based on [elliptic.js](https://github.com/indutny/elliptic).
