Following this Broadcom techdoc to implement an SSL certificate but I cannot download Open SSL since that website is blocked. Can you supply the file?
The aforementioned link above is associated with an unsupported/outdated UIM version v20.3.3.
DX UIM 23.4 link for Self-signed certs:
Configure HTTPS in Admin Console or Operator Console (Self-Signed Certificate)
DX UIM 23.4 link for Authority-signed certs (third-party or Internal certificate authority):
Configure HTTPS in Admin Console or Operator Console (Authority-Signed Certificate)
For information on the supported versions of OpenSSL in each DX UIM version and/or cumulative update see DX Unified Infrastructure Management - Cumulative Updates and Patches (login needed).
Once the required openssl version is identified, openssl v3.5.5 for CU7 for instance, check with your security team to verify which site you are allowed to access for downloading openssl.
