qUUID generates true random UUIDs conforming to RFC 4122 from random numbers retrieved through the API of the vacuum quantum-fluctuation server at the Australian National University. The UUIDs are taken from a space of 2^122 == 5.3e+36 possibilities.
qUUID(n = 1)The number of UUIDs to return. Must be between 1 and 100,000. Default is 1.
qUUID returns a character vector of length n, class "character", type "character" containing n true random UUIDs conforming to RFC 4122.
qUUID returns true random Universally Unique IDentifiers (UUID) that conform to RFC 4122. The construction is based on the function qrandom to generate an input of n 128-bit numbers in hexadecimal representation. These numbers are converted to bit-representations, the 6-bit RFC 4122-required pattern for random UIDs is stamped onto these, and the result is converted back to hexadecimals giving 2^122 == 5.3e+36 possibilities. The resulting UUIDs are patterned like "e3da74ea-b88d-fea2-0b69-56a16caeda0a"; bits 61 to 64 are (00 01 00 00), and bits 71 to 72 are (00 01) (counting from 1).
The true random source is generated in real-time by measuring the quantum fluctuations of the vacuum. The official QRNG@ANU JSON API currently supports only a maximum of 1,024 random numbers per request, thus requests for more numbers are split up into smaller requests of maximum 1,024 numbers. In fact, each request may take a couple of seconds to be served.
