Public and private keys present in the digital certificate are applied via an automated function that is built into standard email platforms; this is virtually transparent to users. Each certificate is issued with private keys that are used for electronically signing your emails and corresponding public keys that others can use to send you encrypted email communications. Once another email user has received a signed email from you, he or she can save your certificate and use the associated public keys to send you encrypted emails. This means that the data that is included in the messages cannot be viewed by anyone who does not have access to your corresponding certificate private keys which are required to unlock the message.
These certificates are compliant with the S/MIME (Secure/Multipurpose Internet Mail Extensions) standard for public key encryption and signing of MIME data.
