 Settings for signing packages or repository. Group name must refer to architecture, e.g. it should be `sign_x86_64` for x86_64 architecture.
 
 * `target` - configuration flag to enable signing, space separated list of strings, required. Allowed values are `package` (sign each package separately), `repository` (sign repository database file).
-* `key` - PGP key, string, required.
+* `key` - default PGP key, string, required. This key will also be used for database signing if enabled.
+* `key_*` settings - PGP key which will be used for specific packages, string, optional. For example, if there is `key_yay` option the specified key will be used for yay package and default key for others.
