Inside SafePal S1 wallet, there implements a firmware verification mechanism that identifies and authenticates every firmware that is uploaded. For each SafePal firmware version, there will be a unique ID tagged to it. This unique ID is created based on the SHA-256 algorithm, an advanced cryptographic hash function used for data authentications. (Click to learn about What is SHA-256?)

- Download or search for an SHA-256 hashing tool.
- Drag the firmware file into the tool obtained from the previous step. Then there will be an SHA-256 ID created for this firmware.
