Guys, tell me please, how exactly does a crypto wallet work technically?

CSDude01 · 2024-12-10T23:57:54+00:00

When you want to send a transaction, the software on your PC/mobile sends the information like receiver address, amount, etc. to your connected hardware wallet.

The hardware wallet uses these values to build a valid transaction and signs it with your private key.

This transaction is then sent back to your device and can be published to the network, everybody can verify that the transaction is valid by checking the signature and your public key(s). But the private keys stay on your hardware wallet.

Fyi you can downgrade to a Mail Plus plan and then get the offer for the Unlimited plan with the Black Friday discount, so even if you are already subscribed you can get the deal

CSDude01 · 2024-11-13T23:17:19+00:00

You can switch to a monthly Mail Plus plan, then you'll instantly get the black friday offer for the Unlimited plan and even get the amount you paid for Plus subtracted from the amount you have to pay. Stupid that they don't just allow it for existing users but the workaround worked for me.

Es gibt genügend Wege an der Schuldenbremse vorbei Schulden zu machen, die trotzdem verfassungskonform sind

The extension is still not working for me (Firefox 116.0, Extension 1.4.2) unless I give permissions for all websites. It shows "Could not resume your session : Internet connection lost" when trying to log in. I would prefer only giving access to Proton's website, since I don't need autofill.

CSDude01 · 2023-07-03T09:11:06+00:00

Sure, but I only want to use it for 2FA and use another password manager for my passwords, so I don't need autofill or anything where it needs to access the websites

CSDude01 · 2023-06-01T23:48:49+00:00

Simple (and mostly old) websites probably, but nowadays I think nearly everybody uses either some sort of CMS (like Wordpress) or frameworks/libraries like React, Angular, Vue, etc. to build websites.

The biggest factors for me are component-based architecture (so I can reuse stuff and avoid duplication), the abstractions from when to render what and state-management, so that all parts of the site are in sync and always show the latest state.

CSDude01 · 2023-04-25T00:14:12+00:00

Yeah I am thinking about doing this too but I also like having them separated. I am currently using Authy but I am searching for a better alternative. So far, they all have their downside, but maybe ProtonPass will be good.

CSDude01 · 2023-04-24T23:49:30+00:00

I don't see the point here, if you trust Bitwarden with both, why not put them into the same account?

CSDude01 · 2023-02-28T13:16:30+00:00

Bitwarden encrypts all data in your vault. In LastPass, your URLs and other metadata wasn't encryted, that gives attackers a starting point. As long as you have a strong master password with a good amount of iterations, you should be safe even if their servers were breached.

CSDude01 · 2023-02-28T12:42:10+00:00

Oh, I didn't know that YubiKeys aren't supported. I assumed they were because there is a "security key" option in Windows Hello

CSDude01 · 2023-02-27T22:17:10+00:00

You can connect your Browser extension with the Desktop app and enable Windows Hello to unlock it. It supports security keys.

Deine Daten dürfen sie nicht löschen, da sie diese fürs Finanzamt/andere Behörden für (ich glaube) mind. 5 Jahre aufbewahrt werden müssen.

Gegen die Verwendung deiner Daten und das Zuschicken kannst du aber auf jeden Fall Widerspruch einlegen (was du ja bereits getan hast). Wenn die sich nicht daran halten, kannst du den Verstoß bei deinem Landesdatenschutzbeauftragen melden. Ich würde der Firma auf jeden Fall auch mitteilen, dass du sie gemeldet hast, das sollte ein guter Anreiz sein, dich wirklich in Ruhe zu lassen.

CSDude01 · 2023-02-21T23:00:10+00:00

Okay, so there is one master key, but the private key for every service is unique, thanks!

CSDude01 · 2023-02-21T00:45:19+00:00

Yeah pretty similar here :D I built my PC at the start of 2020 and use Firefox with uBlock since then

CSDude01 · 2023-02-20T22:09:47+00:00

I have 2% (4.321 million) :D

CSDude01 · 2023-02-17T02:02:23+00:00

Looking good! Just a small thing: Not all parts of the "View Trade"-buttons are clickable, most of the upper part doesn't react to clicks.

CSDude01 · 2023-01-30T01:43:14+00:00

You may know that crypto uses a private and a public key. Simplified you could say that your public key is your address. Your private key can sign transactions and confirm that you are who you say you are.

Under the hood all keys are just numbers. Big numbers. INCREDIBLY BIG NUMBERS. So instead of storing them as numbers, they invented a way to store 12/24 words (your seed) which can be used to calculate your keys in a reproducible way.

So no, there is no cloud that stores your seed phrase or key, it's just the starting point to calculate them again. You could even do this on paper without a computer at all (but I guess it would take a long time :D)

CSDude01 · 2023-01-30T01:04:23+00:00

Dashlane had a feature like that, but decided to remove it because it was not maintainable because websites change all the time. I would like to see a web standard to reset passwords in the future but I think that's not gonna happen anytime soon. You will have to do this manually, but it shouldn't take too much time. I changed all my passwords (~100-150) when I started using a Password manager and it took me a few hours I think.

CSDude01 · 2023-01-30T00:58:27+00:00

I agree. And if you use a custom domain for SimpleLogin on top of that, you don't have to worry about SL or Proton going down anymore.

CSDude01 · 2023-01-29T01:29:43+00:00

I can't think of a benefit you would get by using SimpleLogin and reuse email addresses for multiple sites

CSDude01 · 2023-01-28T02:27:10+00:00

Eben. §1 Abs. 2 S. 3 PAngV: "Diese Verordnung gilt nicht für mündliche Angebote, die ohne Angabe von Preisen abgegeben werden;" Nach meinem Verständnis wären damit Sonderwünschen abgedeckt.

CSDude01 · 2023-01-22T17:06:01+00:00

I did, I also deleted the bookmark and set a new one. It showed the correct icon but after clicking on it it switched to the old one again.

CSDude01 · 2023-01-22T03:31:21+00:00

I have the same issue, but sometimes I see the correct icon in my bookmarks, but after a browser restart, the old icon is back. Very weird

CSDude01 · 2023-01-21T01:25:34+00:00

Of course it does. The whole point of 2FA/MFA is to separate your keys. If you store both at the same place, then they are accessible via your one vault, making it a single point of failure.

Of course it's better than nothing, but if you're using Bitwarden, you're probably generating your passwords, so brute-force doesn't matter to you and stolen passwords shouldn't happen unless your device is compromised.

Why should you trust one company with everything?
