Cryptographically secure randomness

Cryptographically secure randomness for agents that are deterministic or sandboxed. Two modes: raw bytes (?bytes=1..1024, default 32, clamped) returning hex and base64url; or uniform integers (?min= and ?max= together, optional ?count=1..1000) rejection-sampled so there is no modulo bias. Errors: 400 bad_bytes for a non-integer, bad_range when max is not greater than min, range_too_large. Generated server-side, and the response says so - if nobody may have seen it, generate it yourself.

Input

Random bytes to return, 1..1024 (default 32). Returned as hex and base64url.
How many integers, 1..1000 (default 1). Integer mode only.
Upper bound (inclusive) for integer mode. Must be greater than min.
With max: return uniform integers in [min, max] inclusive instead of bytes.
