RNG API
Cryptographically secure random number generation. Certified fair. Auditable. Powers all our draws and winner selection.
What It Does
NIST-approved random number generation for provably fair draws.
Cryptographic Security
FIPS 186-4 compliant. Hardware entropy sources. Seeded randomization.
Gambling Commission Certified
Audited and approved for UK lotteries and draws. Full compliance documentation.
Verifiable Results
Cryptographic signatures. Public seed values. Third parties can verify fairness.
Batch Generation
Generate millions of random numbers in seconds. Bulk processing supported.
Configurable Output
Integer, hex, binary, or custom ranges. Weighted distributions supported.
Audit Trails
Immutable logs of all generations. Timestamps and signatures for compliance.
How It Works
Request
Specify range (min/max), quantity, and optional seed value.
Generate
NIST algorithm generates random numbers from hardware entropy.
Sign
Results cryptographically signed. Timestamp and metadata included.
Return
Results returned with signature. Immutable audit record created.
