Detailed explanation-1: -Digital signatures actually only show that the public key labeled as belonging to the person was used to encrypt the digital signature. Digital certificates cannot be used to identify objects other than users.
Detailed explanation-2: -Digital signatures rely on asymmetric cryptography, also known as public key cryptography. An asymmetric key consists of a public/private key pair. The private key is used to create a signature, and the corresponding public key is used to verify the signature.
Detailed explanation-3: -The public key of the digital signature is linked to the signing entity’s electronic identification. The digital signature can only be affixed by the holder of the public key’s associated private key, which implies the entity intends to use it for the signature.
Detailed explanation-4: -In cryptography, a key is a value used with an algorithm to encrypt and/or decrypt data. A private key, also known as a secret key, is kept on its owner’s system and never transmitted publicly. A public key, as the name implies, is openly available to anyone who wants it.
