BigNumber.Config.CRYPTO property

A boolean: true or false. Default value: false.

The value that determines whether cryptographically-secure pseudo-random number generation is used. If CRYPTO is set to true then the random method will generate random digits using crypto.getRandomValues in browsers that support it, or crypto.randomBytes if using a version of Node.js that supports it.

If neither function is supported by the host environment then attempting to set CRYPTO to true will fail and an exception will be thrown.

If CRYPTO is false then the source of randomness used will be Math.random (which is assumed to generate at least 30 bits of randomness).

See BigNumber.random.

// Node.js
global.crypto = require('crypto')

BigNumber.config({ CRYPTO: true })
BigNumber.config().CRYPTO       // true
BigNumber.random()              // 0.54340758610486147524
