What PKI objects are stored in memory and what are the average sizes?
The following PKI objects are stored in in flash and run-time memory:
Each CA certificate typically uses three objects (CA certificate, CRL, and CA profile configuration). Each local certificate uses two objects (certificate and key pair). A pending certificate is a PKCS10 file that has been generated and sent to a CA. When the signed certificate from the CA is installed the pending certificate object is replaced with the local certificate.
The average sizes for PKI objects are as follows:
