Did you know this? And that digital signatures use private and public keys?

Had to learn this when I became a middleware admin. What tripped me up later in my career was cross-signed certificates.

"If I wanted to send you something and you want to make sure it came from me, I would encrypt with my private key and only my public key can decrypt". Not exactly, this is not "encryption" per se, this is called signature. You sign with your private key and the public key confirms the message came from you. The message contents might still be intercepted. If you want confidentiality, you need to encrypt the message with the recipient public key and only the recipient private key can decrypt.

yeah, thats what I was thinking. I assume he wanted to simplify to convey the general idea. Im sure the fact that RSA decryption and signing, and encryption and verification are the same fundamental algorithms respectively :p

Encrypt with your private key is not how you should call it. That operation is called signing. To encrypt something you use a public key of someone else (or establish a shared secret and use that) and you could also sign it with your private key.

Literally same with your email Public key is your email address.. its is accessible and available Private key is your email password. when someone is sending you a message using your email address ( Public key) and only your private key can decrypt it (Your password to access and see it) and when you will need to send it using your private key (when you are connected to your email accoun and you write your email) and it uses your public key to send your message to the other person ( your email address when it appears to the messages of the other person mailbox) that is your public key.

This is how TLS is utilized in many cases; A receiver will initiate a request to a website by; ENCRYPTing their public key with the website's public key, received from their certificate. The website will then; DECRYPT the payload with their private key, Providing the website with the receivers public key. The website will then; ENCRYPT the data requested with the receivers public key, The receiver will then; DECRYPT the data received from the website with their private key.

@comeycallate9959 3 ай бұрын

yeah, but how do you provide the clients with the public key without the message been intercepted because the attackers have access to the same public key?

Private Key Encryption - Document signing where docs are signu using Private key and anyone can validate it with public key. Public Key Encryption- Whatsapp - Sender encrypt message with ReceiptA's public and only ReceiptA can decrypt it with their private key.

If I use pub key from google, then only google can see it. That's what's happening on the browser when I send data to backend, but when we get data from google?

@tristancomerford 4 ай бұрын

Not quite. Unfortunately while using Google's certificate as an example of a public key is useful to set context, when it's used as part of an https (or other TLS) session it's a lot more complicated. You want to look at DH Key Exchange.

@aronm5329 4 ай бұрын

I'm studying for my Sec+, and not an expert but basically... Google is a certificate authority (a root CA), so they can issue certificates to domains including thier own, using a public/privatekey signing process. They or another CA can issue certificates to your browser as well. Then they will run the hashing algorithms, as long as the as the keys work and none of the of the certificates are on the CRL (certificate revocation list), you will be able to decrypt any info that comes from Google or any approve site.

So If you encrypt a message with your private key, that means anybody with your public key can decrypt it?

@jjpaq 3 ай бұрын

Yes, the purpose of cryptography like this isn't to hide information but to verify that a message came from you. Going the other way, though, anybody can encrypt a message with your public key, and then you'll be the only person who can decrypt and read it (unless your private key gets stolen).

@jjpaq 3 ай бұрын

@@soundwave3353 there are other types of encryption for that-essentially, information is as secure as the key needed to unlock it, so if a public key can unlock it, it's not secure. If you wanted to hide data, you'd use a key that others _don't._ Even signing it with your own public key would accomplish that.
