A PKI certificate is required when you are using a PKI structure for your digital certificates. This type of setup will require that each user has two types of certificates available. They will need their own certificate, which contains their private key. They will also need a second certificate, which they can share with other users. The second certificate will contain a public key, which is needed in order for this structure to work correctly with the user’s private key.
The Types of Data Contained in a PKI Certificate Depends on Its Usage
A PKI certificate can contain different types of data and information. The amount of information contained in your certificates is determined by its intended purposes. For instance, when the certificate is used to encrypt and decrypt data, you do not have to include a digital signature. However, if you want to use the certificate to electronically sign your documents and files, then you will need to include the signature.
