Good evening,
i would like to check my understanding in PKI:
1-if we have 2 HOSTS (Host A and Host B) under same CA, what will happen is :
each Host will receive a local certificate and CA-certificate from the CA.
Host A will receive the local certificate from Host B and will use the CA-Certificate to validate it ???????
2-If we have 2 Host under different CAs (CA-sales , CA-marketing) but of-course the 2 CAs under a common root-CA what will happend is :
-Host A will receive a local certificate and CA-certificate from CA-sales and also receive a CA-certificate from the Root-CA
-Host B will receive a local certificate and CA-certificate from CA-marketing and also receive a CA-certificate from the root-CA
-Host A will send the local certificate and the CA-Certificate(CA-sales) to Host B
-Host B will use the Root CA-Certificate to validate the received CA-Certificate(CA-sales) and then will use the CA-Certificate(sales) to Validate the received local certifcate of Host A
