I am researching on securing IoT devices connecting to cloud services over public internet. I am not using any of the Cloud providers certificate management service. Would like to setup our own to keep cost manageable.
While searching on this I came across CFSSL: Cloudflare’s PKI and TLS toolkit, it’s completely new to me.
Wondering if I can use CFSSL to generate self-signed certificates for each IoT device and the device can use the certificate when device talk to our cloud services ? Also can I deactivate the existing certificate assigned to specific device ?
Appreciate any help on this.
