function hexPairsToAb(string) {
    let arrayBuffer = new Uint8Array(Math.ceil(string.length / 2));
    for (let i = 0; i < string.length; i += 2) {
        arrayBuffer[i / 2] = parseInt(string.slice(i, i + 2), 16);
    }
    return arrayBuffer;
}

let aBuff = hexPairsToAb(hexString);

function abToHex(bytes) {
    return Array.from(bytes).map((byte) => byte.toString(16).padStart(2, "0")).join("");
}
