Digital certificates allow for secure electronic communication and transactions over the internet. There are three main types of digital certificates: secure socket layer (SSL) certificates, code signing certificates, and client certificates. SSL certificates secure credit card transactions and login information on a website using encryption. Code signing certificates digitally sign software to authenticate that it comes from the claimed publisher. Client certificates contain information about a client that allows a server to identify and authenticate the client during a secure session. Digital certificates are issued by certificate authorities to facilitate secure e-commerce and internet communication using public key infrastructure (PKI) technology.
