Certification is a validation of a credential awarded by an independent third-party, such as an accrediting body. It helps establish credibility and expertise in a specific field or technology.

The main purpose of CAs (Certification Authorities) is to provide confidence and trust for the users of their digital certificate. A CA digital certificate ensures that the party presenting the certificate is in fact the real holder of the public key, and that the public key is authentic and belongs to the owner or organization that the certificate represents.

Digital certificates are based on the public key infrastructure (PKI) scheme, and are used to secure various types of data and applications. Some common uses of digital certificates include securing SSL/TLS encrypted traffic, authenticating domain ownership, and verifying the identity of users and servers on the internet.
