Big endian

Open williamgoodhew opened this issue 5 years ago • 2 comments

Is there a way of ensuring the big-endian network byte order is maintained? I am using the 128 key in ECB.

here is my current code:

    const key = Buffer.from("20572F52364B3F473050415811632D2B", "hex")
    const text = '0x060x010x010x01'
    const textBytes = aesjs.utils.utf8.toBytes(text);
    console.log('textBytes: ', textBytes)

    const aesEcb = new aesjs.ModeOfOperation.ecb(key);
    console.log('aesEcb: ', aesEcb)
    const encryptedBytes = aesEcb.encrypt(textBytes);
    console.log('encryptedBytes: ', encryptedBytes)

    const encryptedHex = aesjs.utils.hex.fromBytes(encryptedBytes);
    console.log('encryptedHex: ', encryptedHex);

@williamgoodhew did you ever figure this out? you're also trying to unlock an eddystone beacon?

Sorry. Just saw this.

I do not use any host ordered objects (i.e. uint32Array) in the code, so network order should always be preserved. More specifically any order should always be preserved as everything is operated on as a binary stream of bytes...

can you include output in your example that have the order change?
