Types of Digital Certificates
- Extended Validation: This provides comprehensive business authentication, which is necessary for handling extremely sensitive data for businesses or larger organizations. Businesses in the financial sector usually employ it because it provides the highest degree of trust, security, and authenticity.
- Client Certificate: A client certificate is a digital identity that uniquely identifies a person to another user, computer, or machine to another. Email is a typical example of this, in which the sender digitally signs a message, and the receiver verifies the signature. This is the most effective way to verify the certificates.
- Code Signing Certificate: This is required to verify the legitimacy of software or files obtained from the internet. When consumers download software, the developer or publisher signs it as proof that it is authentic. For software companies that provide their products on external websites, this is a helpful way to demonstrate that the files remain unaltered.
- TLS/SSL Certificate: A program, mail, or web server, for example, uses a TLS/SSL certificate to guarantee and secure encrypted and confidential communication with its customers. The certificate gives the server the authentication it needs to transmit and receive encrypted communications to clients.
- Domain Validated: Any website can use a quick validation technique that works with a domain-verified certificate. It is inexpensive to get and is ready to use in a few minutes.
What are Digital Certificates?
A Digital Certificate referred to as a public key certificate, is used to establish a cryptographic link between the owner of a public key and that entity. These are used to exchange public keys that are needed for authentication and encryption.
The certified public key, metadata about the certificate holder, identity information about the public key, and a digital signature of the public key created by the certificate issuer make up a digital certificate.
