function readAsArrayBuffer(file) {
    return new Promise((resolve, reject) => {
        const reader = new FileReader()

        reader.onload = (event) => {
            resolve(event.target.result)
        }

        reader.onerror = (error) => {
            reject(error)
        }

        reader.readAsArrayBuffer(file)
    })
}

const buffer = new Uint8Array(await readAsArrayBuffer(file))
const fingerprint = cf_fingerprint(buffer)
