MySQL keyring problem

[marco gianfelice]

Hello!

I'm new with MySQL and i'm trying to install keyring on MySQL Community 8.0.11.

i'm using Windows and i edited my.ini file with

[mysqld]
early-plugin-load=keyring_file.dll

then i ran

mysql> install plugin keyring_file soname 'keyring_file.dll';

and i get a warning

+---------+------+--------------------------------------------------------------------------------------------+
| Level | Code | Message |
+---------+------+--------------------------------------------------------------------------------------------+
| Warning | 29 | File 'C:\Program Files\MySQL\MySQL Server 8.0\lib\plugin' not found (OS errno 13 - Permission denied) |
+---------+------+--------------------------------------------------------------------------------------------+
1 row in set (0.00 sec)

i check if it was active and

mysql> SELECT PLUGIN_NAME, PLUGIN_STATUS
-> FROM INFORMATION_SCHEMA.PLUGINS
-> WHERE PLUGIN_NAME LIKE 'keyring%';

that plugin was active.

But when i try to modify my table with

mysql> ALTER TABLE example ENCRYPTION='Y';
ERROR 3185 (HY000): Can't find master key from keyring, please check keyring
plugin is loaded.

I don't get what i am missing.

plugin_dir is the correct one
(C:\Program Files\MySQL\MySQL Server 8.0\lib\plugin)

and keyring_file_data is the same!
