Random Number Beacon

Based on NIST's new beacon prototype.

The idea is to generate "random" bits at specific intervals to allow for two parties which don't trust each other to agree on a shared random number. For example, they might agree to use the next generated number from a third party beacon.

"Beacon-bits" are signed, and hashed with the previous bits. The first bits are hashed with the public key. This chains all the bits together. All hashing is done with the base64 encoded bits so that you can copy and paste what you get from the server to check it "by hand".

API for the sample server:

Note: all calls are HTTP GET requests.

Returns the latest bits

Returns the raw audio (no headers) used to generate the last bits to verify the bits were generated correctly. Only the most recent audio sample is stored on the

Same as /raw except has properly formatted audio header (top 44 bytes) so you can listen to it with any reasonable audio player and decide if the noise is suitably random to your preferences.

The public key used to sign bits.

Returns the bits with specified id.

Returns the bits closest to, but before, the given time. Time is unix time, so number of seconds since Wed Dec 31 1969 16:00:00 GMT-0800 (Pacific Standard Time)

Same as before but closest time after the given time.
