# Usage examples for Infinite Noise
## Integrate the binary to python
See the python examples `serial-numbers.py` and `randomserver.py` to see how you could integrate it with python.
#### serial-numbers.py
An extended version of this script was used to generate the serial numbers of all Infinite Noise's made by 13-37.org. The numbers generated by this simpler one are not guaranteed to be unique, thats why I use the UNIQUE constraint of a database when storing them.
This simple version just prints the serials to stdout. Call like this:
$ ./serial-numbers.py -c 3 -l 8
0A8BBA15
0341F762
813DC0BD
#### randomserver.py
A simple webserver based on the web.py framework to serve random data via a REST interface.
An improved version is hosted on [rng.13-37.org](https://rng.13-37.org).
## libinfnoise
Under libinfnoise/examples you'll find two examples on how to integrate libinfnoise, which consist of the following functions:
// returns a struct of infnoise_devlist_node listing all connected FTDI FT240 devices by their USB descriptors
devlist_node listUSBDevices(char **message);
// initialize the Infinite Noise TRNG - must be called once before readData() works
bool initInfnoise(struct infnoise_context *context, char *serial, bool keccak, bool debug);
// Reads some bytes from the TRNG and stores them in the "result" byte array.
// The array has to be of sufficient size. Please refer to the example programs.
// (64 byte for normal operation or 128byte for multiplier mode)
uint32_t readData(struct infnoise_context *context, uint8_t *result, bool raw, uint32_t outputMultiplier);
The infnoise_context struct is also part of the interface. See [libinfnoise.h](../libinfnoise.h) for it's definition and the interface documentation.
