Random bytes and numbers
Generate random bytes and bounded numbers for security tokens, game logic, simulations, and other application needs.
Verified Randomness API
Randomness results with records you can verify later
Rantropy provides random bytes, numbers, shuffling, sampling, and distribution workflows over REST and gRPC. Requests and results are connected to evidence records so important random outcomes do not disappear as untraceable one-time events.
Preparing for commercial launch
We are preparing the public AWS Marketplace release and can review technical requirements and pilot plans before launch.
API scope
Randomness functions ready for application workflows
A consistent API exposes common random workflows on top of a security-focused randomness core.
Shuffling and sampling
Randomize list order or select samples under defined conditions without rebuilding the core logic in each application.
REST and gRPC
Choose between familiar web integration and persistent, latency-sensitive server connections.
Evidence and review
Make random outcomes reviewable after the event
Requests, output hashes, usage, and timestamps are connected into material that customers and auditors can inspect.
Per-request evidence
Connect each randomness request and result to an identifiable record that can be retrieved when needed.
Integrity verification
Use hash chaining and Merkle proofs to make missing records and later modifications detectable.
Audit export
Provide evidence formats suitable for external review instead of relying only on an internal service screen.
