A free entropy service utilizing the Infinite Noise TRNG is now live on https://rng.13-37.org !
Using this service, anyone can explore, test and use the Infinite Noise TRNG for free – without having to buy the actual hardware.
You can register using the form on rng.13-37.org/register – or this iframe. No personal data required.
You’ll receive an API token after solving the captcha.
Token’s not used for over 30 days will automatically be removed/invalidated.
# Get some SHA-3 whitened entropy (binary) curl https://rng.13-37.org/random?token=12345 # Get some SHA-3 whitened entropy (in hex) curl https://rng.13-37.org/random?token=12345?hex=1 # Get some raw entropy (in hex) curl https://rng.13-37.org/raw?token=12345?hex=1
Be aware that the service is provided on a best effort base with no warranties or whatsoever.
Please be nice with it; it is hosted on a Raspberry Pi.
As soon as the code has been cleaned up a bit (and worked for a while) it will also be made available publicly.
Spoiler alert: all captchas and API tokens are also generated from the internal entropy pool.
