You need to AES encrypt the payload first just like you did for previous version and then rsa encrypt it

**Currently it's not possible to decrypt the BDA afterwards, you can obviously see it using breakpoints but it's pretty annoying

Note

You will still have to set breakpoints to get site-specifc presets

New BDA values

• vsadsa

return window.navigation.entries().length

• basfas

const p = window?.performance;
const m = p?.memory;
const limit = m?.jsHeapSizeLimit;

if (!p) return [1, null];
if (!m) return [2, null];
if (!limit) return [3, null];

return [0, limit];

• lfasdgs

return window.arkl.cbid

There are also some new mechanisms to edit the bda values dynamically, for example you can see that screen_pixel_depth which is typically 24 on chrome is now 72, which is 24 * 3 this is caused by code that looks something like this:

let enhanced_fp = bda[4]?.value;

if (enhanced_fp[26]?.value) {
    enhanced_fp[26] = {
        key: enhanced_fp[26].key,
        value: enhanced_fp[26].value * 3
    };
}

this also happens for network_info_rtt_type on something like this:

let enhanced_fp = bda[4]?.value;

if (enhanced_fp?.[25] && enhanced_fp?.[1]?.value && enhanced_fp?.[18]?.value) {
    const webgl_extensions_hash = enhanced_fp[1].value;
    const webgl_hash_webgl = enhanced_fp[18].value;
    enhanced_fp[25].value = {
        key: enhanced_fp[25].key,
        value:
            typeof webgl_extensions_hash === "string" && webgl_extensions_hash.length > 12 &&
            typeof webgl_hash_webgl === "string" && webgl_hash_webgl.length > 12
                ? webgl_extensions_hash.slice(0, 3) + webgl_hash_webgl.slice(0, 3)
                : "abcdef"
    };
}

New values

• ark-build-id: new header, you can find the value its set to in api.js, this header is only used in the /gt2/ request

Updated values

• navigator_permissions_hash which was previously renamed in 3.5.0, has been reverted to its original name
• bda -> c, again this is for the /gt2/ request
• data[blob] used to not be set at all in the payload when there was no blob, now if there is no blob the value in tha payload is set to data[blob]: "undefined"
