- What is a digital signature? This walkthrough demonstrates how to create a private key, public key, digitally sign a document, and verify.

Great, thank you!
Thanks! You're welcome!
helped with my uni asignment, much thanks :D
Great! Thanks!
Great video ! Thank you helped me solve a university project
Yee i Agree with that Statement
Yes, I agree with that Statement!!
Hahahhahaha
Awesome. good to hear you're doing cryptography projects!
Super useful. thanks
Thanks!
Hi there! Thanks for the wonderdul explanation. Is it possible to get original digest from signature using Public key? If yes then how?
No not possible. You only verify the signature using the public key and the digest
Are signatures appended to the message and the keys must produce the digest for the message with the appendage for verification, similar to salting a password?
Your public key is publicly available i.e. any other party should know that this public key is yours. The message is just the message. If you want to show that you agree to the message, you sign it. That signature is used in combination with your public key, plus the message itself, to verify that you signed it. This is where non-repudiation is - you must have agreed if you used your private key to sign
how can we sign an xml file using a already generated csr file. for example I have a csr generated and I want it to sign an xml document so is there any command?
Hi there! How can you show the digital signature in a hex format?
Good question. I'm not sure. Might have to convert binary into hex using another tool?
Oh, I completely forgot, I have an example using hex on my website: www.digioli.co.uk/digital-signature-with-openssl/
