AliyunDrive ECC Signature

Welcome star, issue and pull requests.

What can it do

1. Generate random ECC key-pair to create a new session.
2. Get the file’s download url without invalid X-Device-Id.

How to use

1. Set the deviceId in line 7.
2. Set the userId in line 8.
3. Set the authorization in line 34.
4. (Optional) Set the private key in line 11,12. (Only if you want to use custom key-pair.)

Some details

1. deviceId could be found in DevTools -> Application -> Local Storage -> cna.

2. userId could be found in DevTools -> Application -> Local Storage -> token -> user_id.

3. authorization could be found in Network, choose any request, Request Headers -> authorization.

4. private key could be found in DevTools -> Application -> IndexedDB -> ALIYUN_DRIVE_CLIENT_SIGNATURE -> signature -> privateKey.

   private key will be generated automatically, so there’s no need to specificate.

Last

There’re some problems need to be solved.

• How to generate a deviceId?

  Just a UUIDv4 string, So you can generate a deviceId randomly.

• How to generate authorization from cookie or local storage?

• How often is nonce updated? (Could be frozen?)

Test

You can use ali_renew_test.py to test nonce update.

If nonce is 0, it will create a session automatically.

If nonce is larger than 0, it will renew the session.

Notice: If it fails, try to increase the interval.

Now it could pass almost 1000 rounds 👍
