I recently installed vRealize Suite Lifecycle Manager (2.x) – and from the VVD guide it supposed to have the “generate certificate” option in the solution.
For the version I installed: 18.104.22.168 Build 10150522 it didn’t have the option for such – instead a facility to generate CSR -> upload a Certificates.
For this – I just followed CertGen (https://kb.vmware.com/s/article/2146215) to get the certificate. The resulting certificate I uploaded.
You just need the one that says: (open the README.txt)
Base 64 encoded. Certificate and Root cert without private key.
