Truly random number generator API

softwarerecs.stackexchange.com › questions › 33783 › truly-random-number-generator-api

Random.org has (among other things) a free HTTP API, and a new JSON API is currently (june 2016) in beta (keys on request).

The HTTP interface (using GET requests) has an Integer Generator, a Sequence Generator and a String Generator.

The JSON interface call names show what's available there:
generateIntegers, generateDecimalFractions, generateGaussians, generateStrings, generateUUIDs and generateBlobs.
With the JSON interface you can even...

...generate digitally signed random data, such that you can prove it really came from RANDOM.ORG (authenticity) and that your application has not tampered with it (integrity). This is useful if you want your application to implement non-repudiation.

Note that they use a quota system. This is based on IP:

RANDOM.ORG uses a simple quota system to make sure nobody hogs all the random numbers produced by the generator.

Basic API (Release 2) - RANDOM.ORG

The following requests one random number from the [1,8] range and three from the [1,6]. Both sequences are generated with replacement. The numbers could be used as a 1d8+3d6 dice roll. In some fields (min and replacement), the caller gives an array of identical values and in another (base) a single value that will apply for all sequences. The two approaches are equivalent, and both are allowed by the API. { "jsonrpc": "2.0", "method": "generateIntegerSequences", "params": { "apiKey": "6b1e65b9-4186-45c2-8981-b77a9842c4f0", "n": 2, "length": [1, 3], "min": [1, 1], "max": [8, 6], "replacement": [true, true], "base": 10 }, "id": 4352 }

I'd like to recommend one more, a random number generator based on quantum fluctuations within a vacuum. It's called the ANU Quantum Random Numbers Server provided by the Austrian National University. This service provides an API that connects to their lab in real time.

The vacuum is described very differently in the quantum mechanical context than in the classical context. Traditionally, a vacuum is considered as a space that is empty of matter or photons. Quantum mechanically, however, that same space resembles a sea of virtual particles appearing and disappearing all the time. This result is due to the fact that the vacuum still possesses a zero-point energy. Consequently, the electromagnetic field of the vacuum exhibits random fluctuations in phase and amplitude at all frequencies. By carefully measuring these fluctuations, we are able to generate ultra-high bandwidth random numbers.

Along with the API, you also have the ability to see and listen to the results of the random numbers. They also have support for authenticated and secured connections for the live streams and random blocks.

There is even a C# library called "Quantum random number generator in C#" which can be found here.
