Digital certificates are based on public key cryptography. State True or False?TRUEFALSE

The statement "Digital certificates are based on public key cryptography" is True.

Explanation:

Digital certificates are indeed fundamentally interconnected with public key cryptography. They serve as a means to verify the ownership of a public key by linking it to the individual, organization, or entity that owns the key. Public key cryptography, also known as asymmetric cryptography, uses a pair of keys—a public key and a private key—where the public key is used for encryption or signature verification, and the private key is used for decryption or signing.

In practice, a digital certificate contains the public key along with information about the key owner and is signed by a trusted authority known as a Certificate Authority (CA). This ensures that when a digital certificate is presented, the recipient can ascertain not only the authenticity of the public key but also that it has not been tampered with, thereby enabling secure communications over networks such as the internet.

In essence, digital certificates enhance the security and integrity of digital communications, proving crucial in various applications ranging from secure web browsing (HTTPS) to email encryption and digital signatures.
