How do I verify downloaded electrum using signature files?

[TheButterZone]

This is what I get when hitting the version 2.9.3 Windows Standalone Executable file signature.

Actually, after some research, I went to gpgtools.org and downloaded some .dmg file (GPG_suite-2016.10v2.dmg)

But my computer didn't open it.

It says "macOS" no less than 5 times on https://gpgtools.org/

Do you know the difference between macOS & Windows? The first is a pleasurable operating system to use, the other is a daily mind-raping nightmare that can't even be legitimately called an operating system. Why are you trying to run macOS software on Windows? How are you even able to post on the internet?

Bottom line - if there are fellow computer illiterates out there, keep your money in a bank, crypto isn't for us. At least that seems to be the Electrum (and its supporters here) attitude.

Actually, it's "don't spread FUD & keep up obviously false pretenses of 'computer illiteracy' belied by your own ability to post here at all".

Listen Butterball. I don't know if you're actually 16, or only post with the sophistication of a teen-ager.

But someone who uses the internet only as an end user, goes to a few interent pages at their desktop computer, maybe downloads a program once or twice a year to their hard drive, well maybe one day this person decides to join the crypto enthusiasts and buys some bitcoin. He/she deposits bitcoin at an exchange, and then reads several people warning to get their coins off exchanges, maybe buy a  hardware wallet, or download Electrum to their hard drive so they can control their private keys.

So this person comes to Electrum download site, and sees Windows or Mac download, and next to it, something called a signature - something they've never seen before.

What do you think this person will think when they see the gibberish of a signature?

They will say -"If Electrum put it up there, it must be important. But what is this gobbly-gook, what do I do with it - I'm just an internet end-user who has never seen such a thing? How come there are no instructions? Is this signature critical to use electrum? Will my money be at risk if I don't use it?"


What kind of a way is this to treat newbies when they come to download something as important as a wallet that will control their money?


And all you can worry about is your pride? How goddamn thin skinned are you?

Tell whoever is in charge of the download are, to find a way to explain to people what a signature is, and whether it's important enough to be required. Because if people see it up there, they are going to assume it must have been put up for a reason, and not as a decoration.

Now stop worrying about your thin skin, and do something to help people new to crypto have a better user experience.

[TheButterZone]

Stop pretending you don't know what operating system your computer runs.

Stop replying to my posts, teen-ager.

I am not talking about myself, but all future visitors to electrum. Bitcoin's not worth $200 any more, and people who put their $$ into btc wallets deserve to understand better what they are supposed to do.

Don't answer my posts anymore Margarine. I need to hear from people whose minds have been on this planet longer than 16 years.

How do I verify the Electrum download and signatures on a Mac?

Similar as example above, but do it for the dmg files:

Open a terminal window (CMD + space bar, type Terminal --> Enter)

Code:

gpg --verify electrum-2.8.2.dmg.asc.txt electrum-2.8.2.dmg

If for some reason you don't have gpg installed on your system, you can always download a very nice suite (which integrates well with Mail, btw - to encrypt or sign Emails, and manage private/public keys ...)  from https://gpgtools.org.

Example:

Code:

      gpg --verify electrum-2.8.2.dmg.asc.txt electrum-2.8.2.dmg
gpg: Signature made Tue Mar 21 10:42:38 2017 PDT using RSA key ID 7F9470E6
gpg: Good signature from "Thomas Voegtlin (https://electrum.org) <thomasv@electrum.org>" [ultimate]


hey guys, 

I am also trying to verify the electrum signature of my mac but I am getting an error. 


here is what I have done:

i have dowloaded the thomasv@electrum.org private key.

Key id: 0451C3EF

Fingerprint: 2ECD 3D5B 47F6 91C4 D0C7  32EB 4A5A 7F6F 0451 C3EF

Created: June 14, 2017 at 10:08 AM

i copied the entire contents of the signature file that is on the electrum.org file to a text file and named it 'electrum-2.9.2.dmg.asc.txt' and it is the same folder as the 'electrum-2.9.2.dmg' file.

then in terminal i typed the following.


'gpg --verify electrum-2.9.2.dmg.asc.txt electrum-2.9.2.dmg'

Terminal's response is the following


gpg: no valid OpenPGP data found.
gpg: the signature could not be verified.
Please remember that the signature file (.sig or .asc)
should be the first file given on the command line.



What I am doing wrong?

I have a mac and I am having trouble verifying the electrum wallet signature. I followed instructions as best as possible according to this post.


I have downloaded the thomasv@electrum.org public key issued on June 14th, 2017

Key ID: 0451C3EF

Fingerprint: 2ECD 3D5B 47F6 91C4 D0C7  32EB 4A5A 7F6F 0451 C3EF


I copied all the text on the signature file from the electrum.org site and saved it as: electrum-2.9.2.dmg.asc.txt and then placed it in the same folder as electrum-2.9.2.dmg

the contents of the signature file are:

-----BEGIN PGP SIGNATURE-----

then in terminal I exectued the following command:

here is the output i got:

Code:

gpg: no valid OpenPGP data found.

Can anyone tell me what I am doing wrong.


Thank-you in advance

Code:

i believe the gpg is looking for a file with a .sig or .asc type for the signature and you are giving it a .txt file containing the same thing.
try renaming the file and remove the .txt from the end:

Code:

mv electrum-2.9.2.dmg.asc.txt electrum-2.9.2.dmg.asc

then check with gpg

p.s. with a closer look your .asc file content does not look correct either.

p.s. with a closer look your .asc file content does not look correct either.

You're right... it looks like the OP has actually copied the text from the "Windows Standalone Executable" signature file: https://download.electrum.org/2.9.3/electrum-2.9.3.exe.asc !!?!

O.k.

I recopied the correct (electrum-2.9.2.dmg.asc)  signature file into a text file and tried both with a .sig and .asc ending, and still getting the same error. Originally I had accidentally had the signature file 2.9.3 which was the beta version.

gpg finds electrum-2.9.2.dmg.sig file but it appears it does not recognize it as valid Opengpg data.

Like I said, i tried both with a .sig and .asc ending. How does the thomasv@electrum.org PUB key I downloaded from the key server play into this, if in anyway?

What else could I be doing wrong?



the exact procedure I am following for creating the text file is copying the entire contents of it from electrum.org and then pasting it onto textedit and saving it. then I have to rename it because it automatically puts an rtf ending.


thanks again


P.S. Could it be that I am using pgp tools and not GnuPG? Does something maybe need to be changed in the signature file, like the heading maybe?

[HCP]

the exact procedure I am following for creating the text file is copying the entire contents of it from electrum.org and then pasting it onto textedit and saving it. then I have to rename it because it automatically puts an rtf ending.

Can you not just right click the link for the .asc file and select "save link as..."? You should be able to just save the file directly from the browser rather than copy/pasting... it is possible that you are either missing data while copy/pasting or it is screwing up the newline/carriage return characters etc...

How does the thomasv@electrum.org PUB key I downloaded from the key server play into this, if in anyway?

Did you import the thomasv PUB key into your keychain? You need to make sure that you've created your own GPG keypair... and then imported his pubkey so that it can verify the file using it.

It says that the signature is valid now, but there is no indication that the signature belongs to the owner.  Right clicking on the link, did the trick as far being able to read the asc file. This time when I executed the command, it imported one of Thomas's keys from 2011... Not sure if that's correct, you can see exactly what happened from my command above.

Thanks again

[HCP]

It is saying it is not certified by a trusted signature. This is fairly normal... it just means that none of your Trusted signatures has vouched for Thomas' signature.

PGP signatures work on a "web of trust"... for instance: Person A trusts you... You vouch for Person B... therefore Person A will trust Person B because you vouched for them. At the moment, no-one you trust (including yourself) has vouched for Thomas' signature, so you get the warning that the key is not certified... even though it is definitely the one used to sign the file (The "Good Signature" message)

if you want to get rid of that "warning" you just have to add it to your list. not sure the details of it but you basically create your own key and sign everything that you add and tell "GnuPG" that you trust these keys so that warning never shows up for those keys.

The first step didn't work for me. I don't now if it was because it was unable to connect to that keypool hosted on that .mit site, I had to use this:

gpg --keyserver pool.sks-keyservers.net --recv-keys 7F9470E6

Im not sure if this:

gpg --keyserver pgp.mit.edu --recv-keys 7F9470E6 would have worked? maybe you had to do use 7F9470E6 instead of 0x2BD5824B7F9470E6 or maybe it was because of the keyserver... anyhow, this is how it went:

1) download the latest .tar file on the Electrum site
2) do "gpg --keyserver pool.sks-keyservers.net --recv-keys 7F9470E6" on the folder which must contain the signature file + the .tar file
3) untar file
4) "python3 electrum" inside the Electrum folder, this will run Electrum live through python

That is all.
