This is ready @benthecarman

Can you check this and add the blinding stuff tomorrow?

[benthecarman]

Added the blind sig stuff, will just need to make sure we haven't seen the signature before

[AnthonyRonning]

I'm a bit confused how the blinded checking is supposed to work. I do a blind registration with the service:

{
    "service_id": 1,
    "plan_id": 1,
    "blinded_message": "8875ab424681778260d3cc606c8c283a5708a746ef03d37f4bf2ef8acacc6a506c1abbfa7b59f85b21323e13502f6b06"
}

and get back the sig:

{
    "service_id": 1,
    "plan_id": 1,
    "blind_sig": "a512370123f7464b0b33a59ab6e6b625dcea546c58e526c96906c2247adb73231f6a2b9dbeceea07cce759cd11e45b50"
}

Then I register a username with the message and sig:

{
    "pubkey": "552a9d06810f306bfc085cb1e1c26102554138a51fa3a7fdf98f5b03a945143a",
    "federation_id": "c8d423964c7ad944d30f57359b6e5b260e211dcfdb945140e28d4df51fd572d2",
    "federation_invite_code": "fed11qgqzc2nhwden5te0vejkg6tdd9h8gepwvejkg6tdd9h8garhduhx6at5d9h8jmn9wshxxmmd9uqqzgxg6s3evnr6m9zdxr6hxkdkukexpcs3mn7mj3g5pc5dfh63l4tj6g9zk4er",
    "msg": "8875ab424681778260d3cc606c8c283a5708a746ef03d37f4bf2ef8acacc6a506c1abbfa7b59f85b21323e13502f6b06",
    "sig": "a512370123f7464b0b33a59ab6e6b625dcea546c58e526c96906c2247adb73231f6a2b9dbeceea07cce759cd11e45b50"
}

and that passes the check. However, it's the same signature that the server had returned before? So the server can correlate that?

Is this just due to me manually sending requests around and not doing the proper client side unblinding stuff?

[benthecarman]

Yeah you need to unblind it client side.

[AnthonyRonning]

Yeah you need to unblind it client side.

Is it expected that it still cryptographically validates without unblinding it client side?

[benthecarman]

Yeah I think so
