random

Source code of released version | Source code of development version

This version is minimally modified to work with NPM in support of the React Meteor Standalone Mixin

The random package provides several functions for generating random numbers. It uses a cryptographically strong pseudorandom number generator when possible, but falls back to a weaker random number generator when cryptographically strong randomness is not available (on older browsers or on servers that don't have enough entropy to seed the cryptographically strong generator).

• Random.id([n]) - Returns a unique identifier, such as "Jjwjg6gouWLXhMGKW", that is likely to be unique in the whole world. The optional argument n specifies the length of the identifier in characters and defaults to 17.

• Random.secret([n]) - Returns a random string of printable characters with 6 bits of entropy per character. The optional argument n specifies the length of the secret string and defaults to 43 characters, or 256 bits of entropy. Use Random.secret for security-critical secrets that are intended for machine, rather than human, consumption.

• Random.fraction() - Returns a number between 0 and 1, like Math.random.

• Random.choice(arrayOrString) - Returns a random element of the given array or string.

• Random.hexString(n) - Returns a random string of n hexadecimal digits.
