VFn

VFn refers to a digital certificate issued by a trusted third party, known as a Certificate Authority (CA), that digitally binds a public key to a specific entity. This entity can be an individual, an organization, or a device. The purpose of a VFn is to provide assurance about the identity of the entity that possesses the corresponding private key. When a VFn is presented, it allows another party to verify that the public key truly belongs to the claimed owner. This verification process is crucial for establishing trust in digital communications and transactions. VFn certificates are commonly used in various security protocols, such as TLS/SSL for securing websites, to encrypt and authenticate data exchanged between a client and a server. They also play a role in digital signatures, allowing recipients to verify the authenticity and integrity of digitally signed documents or messages. The issuance and management of VFn certificates are governed by established Public Key Infrastructure (PKI) standards.
