Why is Satoshi Nakamoto's PGP Key not currently on bitcoin.org ?

[BitcoinFX]

The genuine Satoshi Nakamoto has a PGP Key, here:

For future reference, here's my public key.  It's the same one that's been there since the bitcoin.org site first went up in 2008.  Grab it now in case you need it later.

http://www.bitcoin.org/Satoshi_Nakamoto.asc

- https://bitcointalk.org/index.php?topic=458.msg5772#msg5772

However, it is not currently on bitcoin.org in its rightful place! Why not?  

The correct PGP Key is here: https://bitcointalk.org/Satoshi_Nakamoto.asc

Quoting for creating another log on the internet web.

Good thing that you have created this topic. I think Thyemos and cobra has an agreement that they will run their sites without interfering each others. So cobra is allowed to add remove anything in bitcoin.org domain. Sad to see that something which is very important for the community is not there any more. By the way, I do not have the full story.

Excerpts;

... "What is Bitcoin’s value backed by?

Bitcoin is valued for the things it can be exchanged to, just like all the traditional paper currencies are.

When the first user publicly announces that he will make a pizza for anyone who gives him enough Bitcoins, then he can use Bitcoins as payment to some extent - as much as people want pizza and trust his announcement. A pizza-eating hairdresser who trusts him as a friend might then announce that she starts accepting Bitcoins as payment for fancy haircuts, and the value of the Bitcoin would be higher - now it would be backed by pizzas ''and'' haircuts. When Bitcoins have become accepted widely enough, he could retire from his pizza business and still be able to use his Bitcoin-savings. " ...

~ Anyone wonder where Laszlo got his idea from? *shrugs*

... "Where can I get Bitcoins?

Find a Bitcoin owner and sell her something - MMORPG equipment, IT support, lawn mowing, dollars or whatever you can trade with her. You can also generate new Bitcoins for yourself by running a Bitcoin network node.

You can buy and sell Bitcoins with PayPal ... " ...

[hatshepsut93]

I'm taking a guess here, but maybe whomever decided to pull Satoshi's key out of bitcoin.org probably thought that since Satoshi wasn't active for so many years, his key shouldn't be easily trusted anymore. So much time has passed, maybe some third party could somehow obtain access to Satoshi's key and use it for something malicious, just like it happened with Satoshi's email and some accounts. Basically, same reasoning why his account on this forum is now locked.

It seems that at some point he removed the signature from the page. And they never put it on the page again.

Glorious! I did not realize that you are an old (ancient) timer until now. Looking at all those old timers are leaving the forum is somehow a hard reality to accept but one has to leave at some point. We all will do.

Anyway, that's a nice contribution from your part in the early stage.

And those three letter agencies - who are they?
Sorry about the things that happened to you.

I understand the sentiment, but PGP keys are designed to go expired after a certain amount of time, and that's because cryptographic signature/encryption algorithms _will_ expire after a certain amount of time, as someone may find an attack in the intervening time period.

PGP key

Key ID: 5EC948A1

Created: 2008-10-30

Fingerprint: DE4E FCA3 E1AB 9E41 CE96 CECB 18C0 9E86 5EC9 48A1

So, the above image lists the issues with Satoshi's key.

• 1024 bit (not large enough to be safe for more than 10 years)
• DSA (not a modern signing standard)
• Created in 2008 (long enough to throw some big computing power to discover the private key)

PGP keys are different to Bitcoin keys, you're supposed to renew the key every few years to mitigate against someone bruteforcing the key, and if you somehow leak your private key, you need to be able to replace that with a new one (and you need to be able to do that so in a way where everyone actually believes it's you that's decided to replace it, and not someone impersonating you)

With Bitcoin keys, these problems don't exist because of Bitcoin addresses. Bitcoin addresses hide the actual cryptographic keys (locked inside a hash) until you spend from them. So the information needed to bruteforce a Bitcoin key is publicly available from the time you send till when it gets 1 confirm on the Bitcoin network, before that it's as secret as your private key. This is not long enough to attack Bitcoin's public keys (ECDSA secp256k1 keys), unlike the 10+ years people have had to attack Satoshi's PGP key (DSA keys).

[pooya87]

the source code still contains the key[1] while the site seems to not have any link to make it accessible publicly.
maybe bitcoin.org needs a "historical" page that can include this key alongside other historical facts and clarify that this key was created 12 years ago and may not be safe anymore. although i don't think there is anything insecure about a 1024-bit DSA key.

Yours or mine? Probably not

But a key belonging to one of the most controversial pseudonyms of all time? You can bet that someone (likely some national intelligence agency) has spent some compute-time trying to bruteforce Satoshi's key (they probably hoped to get lucky early on, but didn't and gave up. Or perhaps they succeeded but didn't come up with a good way to use it)

If someone came back now using Satoshi's PGP keys, there would be a much bigger controversy where everyone argues about if Satoshi's PGP keys have been stolen, and someone is using them to fake being Satoshi (Craig Wrong proved that people are interested in doing exactly this)

So what is your point, @BitcoinFX?

The order of things I would want satoshi to sign to 'prove' identity would be ...

1. The PGP Key.
2. The Genesis Block and/or block 1,2 etc.,
3. The block with the outgoing transaction to Hal Finney.
4. Then Login to either ning / P2P foundation account, forum account login and sourceforge login.
5. Old communications and being able to recall 'private' conversations etc.,

As far as I know, the PGP key has never been signed or in fact been used to sign anything, whatsoever.

This indicates to me that the Key is still to be 'trusted'.

The GMX email service did not incorporate encryption in the web service back then.

So, in all likely hood this PGP key was generated on the very same machine that satoshi used to build and compile early Bitcoin (BTC) wallet releases.

I know vitalik played MMORPG. Did satoshi play as well?

was born in 1994 in Russia and moved to Canada in 2000, where I went to school. I happily played World of Warcraft during 2007-2010, but one day Blizzard removed the damage component from my beloved warlock's Siphon Life spell. I cried myself to sleep, and on that day I realized what horrors centralized services can bring. I soon decided to quit.

I am more comfortable in proving my identity using a bitcoin signed message than a PGP key. I use bitcoin addresses a lot but I barely used a PGP key. As you said it is safer, isn't it a good substitute?

[AB de Royse777]

Do you think that it would be possible that in the future bitcoin address may replace PGP keys?

Not all PGP users are bitcoiner and the same way not all bitcoiner are familiar with PGP. PGP came long before bitcoin and I do not think satoshi ever thought that bitcoin will be such big. So for him PGP was more sense making than singing a bitcoin address.

New PGP key: RSA/RSA or DSA/Elgamal?
- https://security.stackexchange.com/questions/72581/new-pgp-key-rsa-rsa-or-dsa-elgamal

Excerpt;

... "What about key length ? By some freak chance, it so happens that RSA, DSA and ElGamal keys of similar size offer vaguely similar strength (this is pure luck since they rely on distinct kinds of mathematical objects). 1024-bit RSA/DSA/ElGamal keys currently evade our cryptanalytic abilities, but they seem to be within reach of Earth-based technology (if you spend a few hundred millions or billions of dollars in building a dedicated machine and don't mind if it takes 6 months to break a single key). 2048-bit RSA/DSA/ElGamal keys are waaaay beyond what can be done with foreseeable technology. Any key size beyond 2048 bits is the equivalent of buying a red sports car to woo girls.

For your specific case:

    The "sign only" options will yield keys usable only for signatures, and not for, say, encrypted emails. If you want a key usage for encryption you will need to use one of the first two options.

    In older times, RSA was patented (in the USA) so some implementations supported only DSA and ElGamal. Since the patent expired in 2000, any decent implementation of PGP can now handle it just fine.

    DSA signatures are a tad shorter than RSA signatures; ElGamal-based key exchange will use a few more bytes than RSA-based key exchange. We are only talking about a few dozen bytes here; any optimization of that kind will be dwarfed by the loss incurred if you decide to use red oversized keys to assert your manhood." answered Nov 8 '14 at 21:32

[Carlton Banks]

Why didn't satoshi signed with a bitcoin address to prove his identity?

I don't think there was a standard way to do that in 2011/12 (after which Satoshi stopped posting/emailing totally)

Do you think that it would be possible that in the future bitcoin address may replace PGP keys?

I am more comfortable in proving my identity using a bitcoin signed message than a PGP key. I use bitcoin addresses a lot but I barely used a PGP key. As you said it is safer, isn't it a good substitute?

There's nothing wrong with doing it, but you need another way to prove that you own the Bitcoin key. If your email or forum account (or social media) got hacked into, anyone can then write a message/post saying:

"Hi bitmover here, I changed my key for signing messages to 3et7849bfjff9ss0awn4n3m2aswlsonqw"

....then they could change the password to the account too, and your 'bitmover' id would be stolen. PGP is designed to avoid that (but it's still possible to trick people using that kind of social engineering attack with PGP, better awareness of good practices with crypto keys/certificates is the answer)

- https://security.stackexchange.com/questions/72581/new-pgp-key-rsa-rsa-or-dsa-elgamal

you're slightly proving my point here... PGP keys should have an expiry date, or at least the subkeys (of a master key) should. That's why people are asking questions like that on stackexchange.com, and Satoshi eventually almost certainly understood this too. You'd be quite unwise to trust Satoshi's PGP key  from 2008 alone when it's concerning such a significant person.

BTW, the most secure PGP keys use the Ed25519 curve, you need to enable some kind of expert option to use them though (I think it's literally gpg --expert --full-generate-key). Ed25519 keys were not added to GnuPG until 2014 or so, long after Satoshi disappeared.

Not disputing that.  

Indeed that is why my list for accepting proof of the satoshi identity (cyrptographically) has five different points of empirical evidence.

I've signed more bitcoin addresses than Satoshi Nakamoto

My legally hard earned LR was 'confiscated by some 'Three Letter Agencies'.  

Glorious! I did not realize that you are an old (ancient) timer until now. Looking at all those old timers are leaving the forum is somehow a hard reality to accept but one has to leave at some point. We all will do.

Anyway, that's a nice contribution from your part in the early stage.

Assuming LR is a currency. Which one?
And those three letter agencies - who are they?
Sorry about the things that happened to you.

@MyLegacyKit on twitter wrote a nice thread on Bitcoin's early stage history ...

"Not for the first time (remember my early Bitcoin exchanges thread?), it amazes me how bad the early history of Bitcoin has been kept.

On the other hand, that's also the reason why Craig always makes these stupid mistakes in his lies and forgeries lol."

"Bitcoin - The First Exchanges

For a #Faketoshi debunk earlier I wanted to know all the Bitcoin exchanges in 2009-2010. So I turned to BitcoinWiki, Wikipedia, and more. Turns out, they are shockingly incomplete or straightforward presenting misinformation."

I helped him fill in some of the blanks on the exchange / research side of things.

Even Laszlo used my exchange service ...

Thanks for the trade BitcoinFX!

Liberty Reserve was a centralized e-currency or DGC, functioning a bit like PayPal (without Bitcoin back then of course!).
- https://en.wikipedia.org/wiki/Digital_gold_currency

However, it transpired that it was operated by 'crooks' and was closed down in 2013.

Lot's of payment processors and online shops used to accept LR for (entirely legal) purchases, much like with Bitcoin today (however, it seems it also had shady users).

I used LR to back my Exchange service by doing profitable micro forex trading on the MT4 platform at various LR accepting brokers, mostly XAUUSD.

Multiple LR accounts were 'confiscated', not just my listed exchange account!

Imagine someone just closed down PayPal or your Bank App tomorrow and then you got nothing back, just because they decided someone else is a criminal.

“Governments are good at cutting off the heads of a centrally controlled networks like Napster, but pure P2P networks like Gnutella and Tor seem to be holding their own.”

— Satoshi Nakamoto

Thus far seemingly correct!
