Heißt es „meine Schlüssel meine Krypto“?

Ich habe vor kurzem einen Nano S gekauft, und beim Einrichten habe ich festgestellt, dass der Nano S Ihnen Ihre Schlüssel/Passphrase vorgibt und Sie sie nicht selbst auswählen.

​

Wie kann ich in Anbetracht der Tatsache, dass Ledger mir diese Schlüssel „gegeben“ hat, sicher sein, dass es sich um „meine Schlüssel“ handelt und niemand sonst, auch nicht Ledger, in irgendeiner Weise Zugang zu ihnen hat? Wer kann sagen, dass Ledger, die mir diese Schlüssel gegeben und mir den Nano S verkauft haben, nicht auch irgendwie Zugang zu ihnen haben?

​

Das ist vielleicht eine Anfängerfrage, aber ist es üblich, dass man Schlüssel auf diese Weise „geschenkt“ bekommt? Und sind sie immer noch „meine Schlüssel, meine Kryptowährung“ oder besteht die Sorge, dass Ledger oder jemand anderes Zugang zu ihnen haben könnte?

​

Nebenbei bemerkt, wie weist Ledger jedem Benutzer einen Schlüssel zu? Ist es ein Zufallsprozess, der den Schlüssel generiert, oder ist es ein einzigartiger Code oder eine Hardware-Funktion, die in jeden einzelnen Ledger Nano eingebaut ist?

​

Vielen Dank!

If you initialized the Ledger as a new device, then it generated a new private key (represented to you as the 24 word seed phrase) which is stored internally in the secure module and never exposed online.

Ledger has some good info online on how all of this works.

It generates keys via random generation of words from a 2048 word list iirc

My biggest concern was the Ledger generating the same keys twice. People said there’s a small% chance of that happening but it’s still possible which is scary.

When you enter a pin the first time it creates a key randomly. If there were already a key on it, you would need to know the pin.

I was sketched out at first but once you learn how it works there is nothing to be worried about.

If you get a device with a pin already attached, it’s compromised.

I’ll let the others speak to Ledger’s source and security, but in general terms, you can generate a BIP39 seed from dice (and coin) but it will take you most of a day to do it

HowTo Create a Trezor (BIP39) seed with external entropy (dice).

But if you do, you are not „trusting“ any firmware, or any software at all. Just dice, trial and error. Works for Trezor, Ledger, ColdCard, or anything that supports BIP39 twelve-word recovery mnemonics.

Hello,

Thanks for reaching out.

Rest assured, this is perfectly normal, Ledger hardware generates 24-word recovery phrases based on the BIP39 standard, which is a standard used across the industry. All the words that compose your recovery phrase belong to the BIP39 English word list. You can not choose your own words.

Ledger does not have any information regarding your wallets and accounts, which is a basic security principle. As underlined in Ledger Live Terms of Use, users of Ledger products are solely responsible for the way they use their devices and protect their credentials since Ledger has no access to your data.

I think setting up a passphrase might be what you’re looking for. There is information on the leger site, just mind the warnings. It creates a new set of keys based on your 24 words and a 25th word/phrase of your choosing.

There are many ways to come up with your own entropy with dice, cards, coin flips etc to create your mnemonic if you do not want to trust in computerised pseudo randomness.

Then you take that „existing wallet account“ and import it into the hardware wallet, and whatever software wallet client you want to use with it (without the private keys of course, just pubkeys and addresses like a watch only wallet)
