For security reasons, your wallet encodes signature requests into a format called “base64” to make it more difficult for unauthorized parties to access your personal data.
Here’s how to decode your encoded signature request message into plain text:
1) Tap the orange “use this tool” link on your Withdrawal summary screen. This opens a decoder tool.
2) Paste the entire message copied from your original signature request inside the decoder tool.
3) Tap the “Decode Message” button. You should then see the entire message decoded in plain text.
