Can anyone recommend a MIT licensed javascript library that can generate cryptographically random numbers? I need it to create AES 128 keys, so it has to be top-notch. I've searched online but all the libraries I found are GPL licensed, which isn't an option for me due to legal restrictions. Does anyone know of a suitable library that is either MIT licensed or even better, public?
Thank you in advance.
This post addresses a question that shares similarities with the topic discussed in Generating cryptographically secure pseudorandom numbers in JavaScript?.
Utilizing JavaScript within a browser:
An experimental API available in Firefox and Chrome, titled window.crypto.getRandomValues, enables this functionality.
However, employing other libraries for random number generation within a browser environment poses challenges due to the difficulty of gathering sufficient entropy. Consequently, these libraries may exhibit prolonged startup times or yield randomness of substandard quality.
Several options for random number generator libraries include:
The first two alternatives likely satisfy your licensing criteria, as the BSD license is characterized by its permissive nature. The third option has been included for comprehensive purposes.
In the context of node.js:
Referencing crypto.randomBytes
For those interested, a good resource to consider is crypto-js. It is BSD-licensed and has gained a strong reputation over the past 3+ years.
After my last search, I stumbled upon the MSR JavaScript Cryptography Library, which turned out to be exactly what I was looking for.
It's worth noting that modern browsers now have native support for some cryptography features. For example, Chrome supports cryptographically secure pseudo-random numbers, and IE11 offers even more functions: http://msdn.microsoft.com/en-us/library/ie/dn302338%28v=vs.85%29.aspx
