These third parties are known as Certificate Authorities, or CAs. And CAs issue digital certificates to organizations, servers, and individuals. The purpose of the certificate is to securely tie a public key to its owner. Now there are a few technologies involved in creating these certificates. The first important technology is the cryptographic hash function. A hash function is a mathematical algorithm that takes a variable length input and translates it into a unique fixed length output. The most common hash algorithm is the Secure Hash…
