Embed your PK to an Image.

Do you keep text file, paper note to save your private key?

What if you can save it to an image file, and nobody knows what's inside it but you?

Your key or any messages will be encrypted on your machine and saved to an image file you want.

And only you can decode it later.

Test embedding a key (Don't use real PK, just type 'Any' text you want.)

Mobile and Desktop
Use preset image Use this preset image, and you will recall this image 'may' have Bitcoin private key information.
Mobile
Upload and use your own image Saving the private key to your family photo or anhy image you like and save it somewhere, nobody will think the image contains the valuable information. ;)

Check image

Or try this sample image. Download it to your machine, and again upload here to see the secret message. The password is 'password'.

FAQ

  1. Cautions
    Before we start, I want to emphasize that you should not use your real OK to test how it works on our Web site. Even though I have no time and resource to spying on your message, there can be unepected situations. And when you are using our Mobile app to save your PK, please move and keep the image somewhere safe in a safe storage. Even though it's encrypted, there's always a possibility a Hacker can break this security. Use this at your own risk.
  2. How can an image have secret message?
    An image is a series of pixel information and each pixel comprised of Red/Green/Blue/Alpha values of a color.

    By modifying those color value slightly and reading those slight modification, we can save and read our secret message to/from an image.
  3. Can I edit the image?
    No. Even just saving the secret image from any image editing S/W can break the information! So don't do that, Just viewing is no harm.

    So just enjoy watching the image, and if you want to change the secret message or read it, please come to this site again.
  4. Can you see any of my information?
    No we can't. All your password, private key, or any message you enter here is calculated and modified by JavaScript code running on your WebBrowser. And information is encrypted that can be decrypted only by your password in your head. Our server receives only that encrypted information and just save it as it is.

    Also when we check the secret message from your image, the server extract the message as it is which was given in encrypted state. Decryption happens by the JavaScript code running on your WebBrowser, and it requires your password.

    If you know how to use WebBrowser debugging tool, yourself can check to see what packets are going through. Even you can install network sniffing tool to read the actual data come and go. All you will see is encrypted data.

    All our Mobile Apps also, we don't collect any of your private information. All text, or camera images are used only for local use.
  5. So is this super safe?
    Nothing is perfect.

    As I warned above, the secret message inside an image can be damaged by saving it with image editing S/W. So you need to keep the image file with care.

    And even though we encrypt the message, someone with enough computing power can decode the message in some amount of time.

    If you know how to use WebBrowser debugging tool, you can see the packets going through. Even you can install network sniffing tool to read the actual data come and go. All you will see is encrypted data.

    If you want to grasp an idea of how strong the encryption is, please take a look at THIS article.
