Digital Certificates

[subrata23]

Not sure about the presentation - for example for one slide titled "Varifying the Certificate" there is a 7 minute lecture. The slide needs to be broken up in more slides each showing one step of verification process.

I do have one question if you could answer please. In many books you see different uses for public and private keys. I have seen examples where the sender encrypts the messages with his private key and the receive decrypts it with the public key and the other way around. The sender encrypts the messages with the public key and the receive decrypts it with the private key. Which of the two is valid for PKI certificates? It is confusing!

@babouras84 Both have their own use; if you want to send encrypted data to somebody, then public key is used to encrypt and receiver uses private key to decrypt.When authentication of some document is required: for example i am sending you a pdf document, how would you trust that I am sending ? To achieve that , I will do add Digital Signature to the pdf.

Digital signature is nothing but encrypted hash of pdf .This encrypted hash is achieved via sender private key.
