📰 Dev.to · Diego Torres
Learn to implement a cryptographically secure shuffle in JavaScript using Fisher-Yates and CSPRNG
Action Steps
- Implement the Fisher-Yates shuffle algorithm in JavaScript
- Use a cryptographically secure pseudorandom number generator (CSPRNG) like crypto.getRandomValues() to generate random indices
- Replace Math.random() with the CSPRNG in the shuffle algorithm
- Test the implementation for security and fairness
- Integrate the secure shuffle into your application
