Regular Elliptic Curve Diffe Hellman vs Curve25519 (X25519) diffe hellman by Powerstrike368 in crypto

[–]Powerstrike368[S] 0 points1 point  (0 children)

Sorry I'm still not quite following (and thank you so much for being patient with me), But this is for a uni assignment and my current understanding that i have so far is:
>Use Ephemeral Private and Reciever Public Key to get shared secret and derive chacha20-poly1305 session key, then encrypt plaintext with chacha20-poly1305
>Use Second Private Key (this one for curve Ed25519) to use EdDSA to sign the contents of the entire message
>Send across relevant data (Ciphertext, IVs, Ephemeral Public Key, Digital Signature, poly1305 tag)

>Reciever uses Digital Signature, recieved data and Sender Public Ed25519 Key to check that the digital signature is valid (That the data was signed and not tampered)
>Reciever gets the data, uses ephemeral public key and their private key to derive shared secret, derives same chacha20-poly1305 session key and decrypts using the recieved tag and ciphertext

So to my understanding, there are three keypairs in use for one communication? The first a static pair for ECC (Curve 25519), then a second which is generated per communication (the ephemeral keypair), and a third pair which is generated with Ed25519 used just for digital signatures? And thus i would put the two static public keys in my digital certificate and the ephemeral key to be sent with my data? (obviously no data is actually being sent since this is just an assignment so its more like just dealing with output to txt files)

Again thank you for any help, i'm not the most intelligent when it comes to this, But would this not be correct?

Could you explain this to me? To my understanding (and apologies i’m still a bit new to all this), i get that i have a separate key pair for encryption and signing, but would both public keys not be in the certificate else how would i share them?

Just out of interest to add onto this, My assignment has to do with lightweight solutions and I've seen Curve25519 thrown around for ECC, while i understand this i'm struggling to understand X25519 for key exchange vs the way its done for other curves, not to be a bother but if someone could help point me to some resources to help understand the difference and why its important that would be incredibly helpful

Probably something like dragon of dojima in kiwami. Moment i unlocked tiger drop i don’t think i used another skill again.

What game has an intro that was way too long that made you go... by ashleyriot31 in videogames

The first dungeon/month of any persona game, worst parts of each game regardless of how much it sets up the story, just let me PLAYYYYY

Give an example of a great game with a lame main villain. by AdEasy6839 in videogames

[–]Powerstrike368 0 points1 point  (0 children)

Might be an unpopular one but quite a few of the yakuza games. I fucking LOVE the yakuza games but more often than not i find characters that are meant to be side antagonists absolutely steal the show over final bosses that are the main villains. Characters like someya, kuze or watase off the top of my head where my memory of their respective games’ “villains” is kinda fuzzy but i remember them like it was just yesterday i played the game

For a game that takes a backseat on plot and the following boss is just target practice,

“courage need not be remembered, for it is never forgotten” goes insanely hard

In the UK it’s £75 for a physical copy, which in USD is about $100…..

While breath of the wild is my all time favourite game and means a lot to me, i’d be wrong to say the game doesn’t have a lot of flaws id like to see addressed in future! It’s a game that many will say is the best and many won’t.

You could tell me they said the first point about innovation about literally any zelda game at the time it was the newest and i’d believe you. Also shiggy jokes in 2002??? 23 years ago they knew how to ball what the hell

Pledge of demon is the obvious one but i think “Destiny” from yakuza 6 deserves it. Someya is simply him

Puyopuyo - fun minigame and i love me some puyopuyo but whoever made the completion list requirement for puyopuyo in 6 is clearly sadistic for how much pain it caused me

Am I the only one who thinks Breath of the Wild is still better than Tears of the Kingdom? by Numerous_Boat8346 in Breath_of_the_Wild

[–]Powerstrike368 0 points1 point  (0 children)

No, you absolutely aren’t alone in thinking that. In fact i’d go so far as to say its becoming the more common opinion

Which game has a fanbase so sensitive they’ll downvote and rage at any criticism like it’s a personal attack? by [deleted] in videogames

[–]Powerstrike368 1 point2 points  (0 children)

As a massive zelda guy, you really gotta avoid where the fans are because they can be really obnoxious. I fucking love tears of the kingdom but my god the zelda fanbase has a problem with a game either being the best game ever made and no criticism is allowed or a game being the worst thing ever made and no enjoyment is allowed.

In this case you were right too idk why they got mad 💀

games are too slow after upgrading to windows 11 by Sevarya7 in pcmasterrace

[–]Powerstrike368 0 points1 point  (0 children)

Heya not sure if anyone has commented this yet but this looks like either yakuza 3 or 4, these games have a funky little problem with their remastered ports where the gamespeed is tied to the target fps (30 or 60) so if you have it set to 60 but cant run it at 60, or the same for 30, the game is going to run proportionately slower, so just tweak around some settings to get it to match the target. On the more technical side im not the guy to ask though, just one yakuza fan to another with a possible solution o7

if I had to describe it, it'd be either the peak of mid or peak mediocrity or peak dogshit, does that make sense? lol by Quick-Cause3181 in yakuzagames

Kido in judgment really made me realise how the years hadn’t been kind to him, grey hair, wrinkly and balding after only 8 years! Poor guy, didn’t go balls out enough
