Import and Sign CSR via Command Line

[lunakoa]

Trying to find a faster way to sign CSR. Are there command line ways to sign a certificate when XCA is the CA? One way I have thought of was to export the key and sign using openssl then importing the crt into XCA, the issue there is the Serial number, not sure who XCA determines the serial number.

Was hoping to create a way from linux hosts to create the CSR and send it to XCA and have it sign and import it all via command line.

Any challenges or security issues I am not thinking of?
