Not all random values are created equal - for security-related code, you need a specific kind of random value.
A summary of this article, if you don't want to read the entire thing:
Math.random()
. There are extremely few cases where Math.random()
is the right answer. Don't use it, unless you've read this entire article, and determined that it's necessary for your case.crypto.getRandomBytes
directly. While it's a CSPRNG, it's easy to bias the result when 'transforming' it, such that the output becomes more predictable.uuid
, specifically the uuid.v4()
method. Avoid node-uuid
- it's not the same package, and doesn't produce reliably secure random values.random-number-csprng
.You should seriously consider reading the entire article, though - it's

Secure sessions are easy, but not very well documented. | |
Here's a recipe for secure sessions in Node.js when NginX is used as an SSL proxy: | |
The desired configuration for using NginX as an SSL proxy is to offload SSL processing | |
and to put a hardened web server in front of your Node.js application, like: | |
[NODE.JS APP] <- HTTP -> [NginX] <- HTTPS -> [PUBLIC INTERNET] <-> [CLIENT] | |
Edit for express 4.X and >: Express no longer uses Connect as its middleware framework, it implements its own now. |
