As I stated, my sdcard is encrypted on a rooted phone, is there a way to copy encryption key from the system files, so I can just paste the key into the device after factory reset, so I can use it again? Encryption key is random, and not fixed to a device. So where is it stored? In /data ? In /system ? Or in any other location.
The point is that I have a backup of the key, so if my phone decides to die on me, I could factory reset it, paste the encrypt key with root, and use SDcard without decrypting and re-encrypting it?
