A

All right, so we, where are we and where did we leave off? um Well, we still need to do this key stuff. um uh So, let's so, essentially we we understand that um you know we can't use the same key. We got to use a different kind of key uh the um x two five, five one, nine key, which is based off of a different curve um instead of the ed two five five one, nine key uh yeah, which you know has a different curve, and so you can see.

A

In this bit of code here in, I guess: okay, h, g h, yeah, you can see in this piece of code alternately pronounced age that um there's some some some funkiness going on here right. So there's this curve. Two five nine x see this shared secret, fingerprint.

A

Make public key out- and I think we went through this.

A

Encrypt okay! So what are we converting to here? So I think yeah. So so we have to convert to the 2 x25 5 1 9, in order to use it for encryption.

A

Okay, so let's try, I think we already tried this yeah.

A

Oh no there's math make it go away.

A

I extremely want to use a library that does this.

A

And not copy paste unless it's from a library all right, let's see so what do we got here? Cryptocurve exchange using curve25519.

A

This is a hazardous materials module. You should only use it if you're 100 sure that you know what you're doing this module is full of landmine dragons, dinosaurs and and dinosaurs, with lace guns all right. Well, we're gonna hope. We know what we're doing here. um So, let's see I mean I trust uh filippo, so I think, as long as we can confirm that our implementation will match with his implementation, then we should, uh you know basically be very happy all right so from public key bytes. What is this from private bytes? Okay?

A

So this is probably going to be something we're interested in here all right. So let's convert our key all right, so we have import from pem, okay, so copy dot, deep copy. Okay! So actually, let's, let's, uh let's see signing date. So let's call this one: ed, uh uh okay, so keys.

A

A

So let's say assigning.

A

Equals disk and.

A

Okay, so we're going to dump that in there and we're gonna dump this thing in there all right.

A

And we're coming back up one two: three levels: okay, so all right, so we got some keys um loaded, private key from bytes, um so it looks like okay, so here's a private key, bytes, okay, so here's a generated private key encryption, algorithm; no encryption, encoding, encoding raw format, raw okay from cubites, okay, so private bytes, okay. So what is this key generate?

A

So let's go through and look at this, so this supports a generation of a key okay, so private key.

A

Okay, here's another function: it's calling open, ssl, okay under the hood here, all right, so.

A

A

Okay, so yeah, so it's it's messing with with openness, the cell under the hood here. um What does let's see? Let's take a look at filippo's code.

A

Okay, what do we see? What do we see? What do we see so it looks like in comes this.

A

Where is this coming from it's a label? Okay, here's a label.

A

Okay, I'm gonna have to break here.
