The certificate contains the name of the certificate holder, a serial number, expiration dates, a copy of the certificate holder's public key (used for encrypting messages and digital signatures) and the digital signature of the certificate-issuing authority (CA) so that a recipient can verify that the certificate is

Which key is used to create a digital signature?
Using a public key algorithm such as RSA, one can generate two keys that are mathematically linked: one private and one public. To create a digital signature, signing software (such as an email program) creates a one-way hash of the electronic data to be signed. The private key is then used to encrypt the hash.
What is public key and private key in digital signature?
The private key, on the other hand, is kept on its owner's system, never to be transmitted publicly. The sender of an electronic document uses their private key to encrypt that document; this is the digital signature. The receiver then decrypts the signature with the public key to verify that it matches the attachment.
