Hi at all, my 5cents....
security is a relevant part of out job, and having used U.S. for years in prod env, would be great if was possible configure TDE in mysql stack.
Of course we are speaking about a basic form of tde, the only accepted in mysql community version.
Returning to the point, I tried the same configuration for "keyring_file", obtaining same results in mysql error file.
I was very frustrated too..... imho he problem is that the errno:126 is not strictly related to the "keyring_file.dll" but to some others dlls impossibles to discover (by me) and/or not installed/registered (I didn't found any documentation, so maybe I'm wrong...).
At the end my solution have been: install mysql 8.0.30 with the mysql installer, that register all dlls and paths and whatever in windows registry (the opposite that U.S. do) and configuring tde (I choosed the newest way, using "component_keyring_fiel.dll").
By now I'm using Unicontroller to start/stop Apache/PHP and I start/stop mysql by hand, outside Unicontroller.
In such way, my application works fine.
I saw that mysql present in U.S. is a tailored version, but would be great if will be possible have a U.S. version with mysql enabled to configure tde.
Best regards
P.S. Seems that mariadb works better regarding tde........mybe I will try migrating to mariadb......in such case Unicontroller would manage the database also.......
