Digital Signatures and Certificates are a form of digital identification that can be used to prove the identity of an individual or organization in the digital world. They are an essential component of secure communications and transactions in the tech age, as they help confirm authenticity and accuracy.
Digital signatures are created using a cryptographic algorithm and code (known as a public key) which is associated with the creator of the signature. This ensures that any document or message that has been signed with the signature cannot later be changed or tampered with. A certificate, on the other hand, acts as proof that the signature belongs to a particular entity and has not been tampered with or modified. Together, digital signatures and certificates provide an added layer of trust and security to online documents, financial transactions and more.
