Issue: 

The APV WebUI certificate appears to have changed after a certain version. 

According to Bug 1164, version 10.4.2.104 still includes complete details about the Array in the certificate. 

However, in the latest version (10.7), the certificate contains less information.
Solution: 

By using OpenSSL commands on Linux, we generate a certificate with the desired parameters, based on the information from version 10.4.2.104.
The details of the step is written below:

1. Create a new folder on the Linux environment

2. Type the command "openssl genrsa -out private.key 2048" (which will generate "private.key" file)

3. Type the command "openssl req -new -key private.key -out server.csr" (which will generate "server.csr" file)

4. Copy "openssl.cnf" from "rel_apv_10_7/usr/click/lib/libopenssl-1.1.1/openssl-1.1.1d/apps/" to your current working directory

5. Under the "[ v3_req ]" section, copy the parameters below :
Set basicConstraints to indicate this certificate is a CA
basicConstraints = CA:TRUE
keyUsage extension to include Key Encipherment (a0)
keyUsage = critical, digitalSignature, keyEncipherment
Subject Key Identifier and Authority Key Identifier
subjectKeyIdentifier = hash

authorityKeyIdentifier = keyid,issuer 
Enhanced Key Usage extension
extendedKeyUsage = serverAuth, clientAuth

6. Type the command "openssl x509 -req -days 3650 -in server.csr -signkey private.key -out server.crt -extfile openssl.cnf -extensions v3_req"

(This will generate "server.crt" file)

7. Type the command "cat server.crt private.key > server.pem" (This will generate "server.pem" file)

8. Rename the "private.key" into "server.key"

9. Copy "server.crt", "server.key", "server.pem" from this directory to the APV which is "rel_apv_10_7\usr\click\webui\conf\"

After compiling with the updated "server.crt", "server.key", and "server.pem" files, 

upgrade the WebUI using the compiled .array files.
To verify the certificate, you can check it using a browser like Chrome:

- Look for the "Lock" icon or "Not Secure" icon next to the URL.

- Click on it and select Certificate details.
