Verifying the PGP Signature to electrum?

[nc50lc]

but my 1st question now (among many others) is does it matter what name and email address I use at step 1?

That would be for your own PGP/GPG key pair, you can leave the email field empty if you want.
For verifying Electrum signatures, it doesn't matter if you've set an email or not.

Oh and can I download it on an iOS device without being required to verify it via GPG like downloading it on a Windows 10 P.C.?

It's never been a requirement but optional for the users' own safety.

AFAIK, there's no Electrum in the 'App Store', if there's one, it isn't official.
For Electrum downloaded from Android's PlayStore, you should check if it's uploaded by "Electrum Technologies GmbH" since you can't verify an already installed app.
If you want to verify, download the ".apk" and its signature file from electrum.org to verify it in your PC before installing to your device.

I think I did it but it looks different from the youtube video tutorial I watched here:https://www.youtube.com/watch?v=Y0zgZ4M1Bro



This is what it shows me (it had no green coloured background like in the video):


 "Verified ‘electrum-4.4.6-setup.exe’ with ‘electrum-4.4.6-setup.exe.asc’: 3 valid signatures."


                 Signature created on August 20, 2023 7:18:16 PM
With unavailable certificate:
ID: 0x637DB1E23370F84AFF88CCE03152347D07DA627C
You can search the certificate on a keyserver or import it from a file.

I think I did it but it looks different from the youtube video tutorial I watched here: -snip-

That video if for the older Electrum binaries that are signed by ThomasV alone.
The latest now have 3 signatures. Namely; by ThomasV, SomberNight and Stephan Oste (Emzy).

The result that you get is "good enough" for having one valid signature and certified certificate out of the three.
But if you really want a "green result" you should redo the steps to "import" and "certify" the other two developer's PGP key.
You can find their keys here: https://github.com/spesmilo/electrum/tree/master/pubkeys

This is what it shows me (it had no green coloured background like in the video):

I can confirm I hold the following keys locally:

Emzy - 0x9EDAFF80E080659604F4A76B2EBB056FD847F8A7, with subkey 0x637DB1E23370F84AFF88CCE03152347D07DA627C

SomberNight - 0x0EEDCFD5CAFB459067349B23CA9EEEC43DF911DC

ThomasV - 0x6694D8DE7BE8EE5631BED9502BD5824B7F9470E6

These three keys match the keys which have signed your Electrum download, so you are safe to install. As nc50lc says, if you want all three to verify fully you'll need to import and verify Emzy and SomberNight's keys as well.

Ok thank you so much I managed to do it thanks to that one video and your post, and I'd like to find a good Monero Wallet to use with my Hardware Ledger Nano S on my computer as I assume to date it's not possible to send or receive cryptocurrency via a iphone or android device?

If it's about Monero, I doubt people here in Electrum board would be willing to give you answers since it's off-topic.
If you want, you can post a new topic in 'Altcoins' or 'Wallet Software' board regarding that matter.

As for sending or receiving cryptocurrencies in Android or iOS in general, there are a lot of SPV or centralized wallets out there that works in either platform.

[Thomas29]

Okay I'll do that thanks and that's interesting. Ok and I'm hoping this is on topic... how exactly do I use a Bitcoin ATM alongside and Electrum Wallet? I use a hardware wallet too btw.

Both the official CLI/GUI wallet and Feather wallet work with hardware devices. The Monero subreddit is a good resource for Monero info: https://www.reddit.com/r/Monero/

as I assume to date it's not possible to send or receive cryptocurrency via a iphone or android device?

Ledger Nano S devices are not compatible with phones.

You can use Electrum to interact with your Ledger device by following the guide here: https://support.ledger.com/hc/en-us/articles/115005161925-Set-up-and-use-Electrum

Once you've created your wallet, it's a simple as taking the next receiving address from Electrum and sending coins which you have bought to this address.

[Thomas29]

Thanks for the advice @o_e_l_e_o I will go check it out.

[Thomas29]

I keep forgetting exactly how I verified Electrum each time I'm required to do it again for a new update. I was hoping someone could tell me what steps of the PGP verification process do NOT need to be repeated and what steps I do need to repeat to verify it?

Skip the steps from the start to the importation and certification of Electrum developers' public keys.
You should go straight to verify Electrum with the signature (.asc) file, of course download the new signature file that's released with that version.

Ledger Nano S devices are not compatible with phones.

I know I'm a little late to the party here, but that's not strictly true.

I have the Ledger Live app installed on my Android device (Samsung Galaxy S20 FE), and can connect my Ledger Nano S to it using a "USB C to USB A adapter" like this:


and then using a standard USB-A to Micro USB cable to connect the Nano S. (I don't have a USB-C to Micro USB cable to try)


It's fully functional, if somewhat of a janky solution


NOTE: There is a Ledger Live app on the Apple store as well, but I don't have a suitable iOS device (nor the appropriate adapters) to try and test connecting the Nano S to iOS devices.

Thank you so much for this potentially helpful information. I will keep it in mind for the future in case I ever need to use it for a mobile device.

If you need to use Ledger Live on a smartphone, make sure you download the software from a link on the official website. In case of Ledger, it's https://www.ledger.com/ledger-live. Never search for any apps from the App Store or Play Store because there have been many instances of fake phishing apps being posted there. Their whole purpose is to steal your seed and gain access to your coins.
