Aria2 rpc secret token format?

Question

Aria2c rpc user-password authorization marked as deprecated, it is suggested to use security token, but what is the format of that token? Is it like password or what?

Solution

From this issue https://github.com/aria2/aria2/issues/294 I'm assuming, that token is same thing as password -- plain text, without any formatting, but it does not require user name.

There is no Java in aria2c implementation, I'm asking about the format of token string, not how it sent via rpc.
