Detailed explanation-1: -Public keys can be stored by embedding them within digital certificates, while private keys can be stored on the user’s local system. The vulnerability discovered in IPsec in early 2014 was nicknamed Heartbleed, due to an issue with a heartbeat extension in the protocol.
Detailed explanation-2: -This ensures that the public key in the certificate has not been replaced, and belongs to the owner / organization shown in the cert (which was validated by the CA). The certificate cannot be stolen and used by an impersonator, because that person would not have the private key associated with that certificate.
Detailed explanation-3: -PFX Format (PKCS#12) PFX is a format for storing a server certificate or any intermediate certificate along with private key in one encrypted file.
Detailed explanation-4: -Definition(s): A digital document issued and digitally signed by the private key of a certification authority that binds an identifier to a cardholder through a public key. The certificate indicates that the cardholder identified in the certificate has sole control and access to the private key.
Detailed explanation-5: -This can be used to provide authenticity since the encrypted hash must have been produced by the holder of the private key – hence the name digital signature.
