This change addresses a `GeneralSecurityException: Keystore operation failed` error that occurs on certain devices, notably the iMin POS running Android 10. The root cause appears to be a device-specific bug in the Android KeyStore implementation that prevents the generation of a standard 256-bit AES key. To resolve this, a fallback mechanism has been implemented. If the initial attempt to create a 256-bit master key fails, the code will now automatically retry the operation with a 128-bit key. This provides a workaround for the affected devices without altering the behavior for devices that correctly support 256-bit keys.
