HTML Preparation code:

<!--your preparation HTML code goes here-->

Script Preparation code:

const precomp = ['0','1','2','3','4','5','6','7','8','9','a','b','c','d','e','f'];
let hex = '';
let big = crypto.getRandomValues(new BigUint64Array(1))[0];
if (big < 0n) throw Error('neg');

Tests:

toString
hex = big.toString(16);
while switch
while (big !== 0n) { switch (big & 15n) { case (0n): { hex = '0' + hex; break; } case (1n): { hex = '1' + hex; break; } case (2n): { hex = '2' + hex; break; } case (3n): { hex = '3' + hex; break; } case (4n): { hex = '4' + hex; break; } case (5n): { hex = '5' + hex; break; } case (6n): { hex = '6' + hex; break; } case (7n): { hex = '7' + hex; break; } case (8n): { hex = '8' + hex; break; } case (9n): { hex = '9' + hex; break; } case (10n): { hex = 'a' + hex; break; } case (11n): { hex = 'b' + hex; break; } case (12n): { hex = 'c' + hex; break; } case (13n): { hex = 'd' + hex; break; } case (14n): { hex = 'e' + hex; break; } case (15n): { hex = 'f' + hex; break; } } big >>= 4n }
precompute
while (big !== 0n) { hex = precomp[Number(big & 15n)] + hex; big >>= 4n; }
