CH-J · CSPRNG

Public randomness for testing

CH-J Entropy Monitor publishes independent 512-bit random values from the system CSPRNG every 30 seconds and keeps a 60-minute history (up to 120 values). Use them for demonstrations, application tests and experiments with shared public random inputs.

Every value is public. Do not use it as a secret encryption key, password or authentication token.
