Unsure if installed user certificates can be trusted

[Moogie1]

Hi,

while checking the user certificates of my galaxy tab s9 I saw some certificates that I have no clue where they come from and if they are trustworthy. The names of the certificates in question are:

SemSsdidManagerService
gak_ec_alias
gak_rsa_alias

Does anybody have an idea if these are ok? Not ok? Can/should be removed? Where they come from and how I can find out more about the issuer etc.?

Thanks already!

Do you actually go looking for things to worry about?

You put in a search for those names and see whom their from and whether they are good or not.

Thanks, I tried this already, but none of those names yielded any results for me unfortunately.

Look here :

SemSsdidManagerService is related to Samsung services on your phone.

The "gak_rsa_alias" certificate is likely a user-installed certificate on your Android device, which may be used for secure communications or authentication. If you accidentally removed it, you may need to reinstall it or restore it from a backup if available.

The "gak_ec_alias" certificate is likely a user-installed certificate on your device, which may be used for various secure communications. If you're unsure about its trustworthiness, you can check its details in your device's security settings.
