PKI uses public key cryptography in order to encrypt data contained in within digital certificates. The types of data contained within these certificates can be used for different purposes and functions. For instance, you can use a digital certificate to perform authentication processes when connecting to resources over the internet. You can also use this type of certificate for digitally signing documents, in place of traditional paper-based methods.
Make Sure to Set a Validity Period When Using PKI for Your Digital Certificates
The types of digital certificates created with PKI, often follow the X509 standards. It is a good idea for organizations to set a validity period within each of their certificates. You can base the validity period for each certificate on how you intend to use it. For instance, if you are providing the certificate for a single one-time use, then you would want the certificate to expire within a 24-hour period or less.
