- What's PGP, and what can we do with it? George walks us through creating and uploading a key, encrypting and signing emails, git commits, and files, and introduces the web of trust.

That's the best PGP explanation i've ever had. Thank you
This is really nice because you have also taken a lot of effort in explaining cryptography for everyone to understand. Reminds me of my lecturer Dr Rob Holton
Very easily explained by Mr. George. Thanks.
Haha, coincidence that I'm watching this on the exact expiry date mentioned in the 26th minute.
Right?
The web of trust got my like
Nice Tutorial though the Querries at the background r are too much intrerruptive. aber Danke.
What's PGP, and what can we do with it? I use a GUI VERSION of PGP to encrypt
some of my sensitive txt files , et al .
26:00 If you edit the expiry date on your private key, wouldn't that mean that you've broken the web of trust and to reestablish it your friends will need to re-sign it? Does this require extending the expiration date on the key before it expires, since waiting until after the key expires and then extending it would break the web of trust?
Great delivery!
What person in that conference would think Edward Snowden is a bad guy? It's a fucking Emacs talk about PGP?
It's an old vid and I do not expect a reply but if you are available could you please explain the implications of Australias encrypted messaging laws on this technology?
If you have to send a key for authentication why is that not a password?
You only have to send your public key, not your private key.
The public and private key are a pair of which only the public key should be known by others.
The public key can encrypt messages that the private key can decrypt and the private key can sign messages that the public key can verify.
Here's a guide I put together that's pretty complete for the average user.

I WANA USE IT.... EDWARD SNOWDEN IS A HERO!
1. Why PGP private keys are so huge (ie: +6k characters)??? Why not 256bits pk??
2. Is it possible to create a PGP private key by rolling a dice?
1. More entropy equals more security. It's questionable where the point of diminishing returns is, but that point keeps shifting right over time so it is a pragmatic design decision to overprovision this. That said you may be misunderstanding something; most private keys max out at 4096 bits which can be base64 represented in under 700 characters of ASCII. A PGP private key block contains additional metadata -- I don't know this for sure, but it's plausible that this could include a copy of the public key, subkeys, and User IDs.
2. Yes. Finding or developing an implementation of this is left as an exercise to the reader. 🙂

'More entropy equals more security.'
This doesn't make sense. Do you know what algorithm PGP uses? elliptic curve? prime numbers?
'most private keys max out at 4096 bits which can be base64 represented in under 700 characters of ASCII.'
Therefore, the 6k chars I've mentioned would mean a 35k bits PK.
Something must be wrong here.
clever title
the difference between a password and a passphrase? a space “should” be required if the system is asking for a passphrase. That’s it!
Maybe just ask people to save their questions to the end so we don't have minute-long stretches of barely audible rambling?
