I can help you with that. Here’s a step-by-step guide to verify whether you used an authentic version of BitAddress.org by using SHA256 hash string and verifying it against the original HTML file:
Step 1: Download the original HTML file
If you want to verify the authenticity of your BitAddress.org HTML file, you’ll need to download the original HTML file from the BitAddress.org website. You can do this by visiting [ and clicking on the “Download” button.
Step 2: Verify the SHA256 hash string
After downloading the original HTML file, extract its contents using a command-line tool like tar or unzip. This will give you the contents of the HTML file in a file with a .html extension. You can then use a hex editor or a tool like sha256sum to verify the SHA256 hash string.
For example, on Linux, you can use sha1sum bitaddress.org.html | head -n 1 to get the first line of the SHA256 hash string:
$sha1sum bitaddress.org.html | head -n 1
...
This will show you a shortened version of the SHA256 hash string.
Step 3: Verify against original HTML file
Compare the SHA256 hash string from Step 2 with the original HTML file’s contents. If they match, it means your BitAddress.org HTML file is an authentic copy.
For example:
$sha1sum bitaddress.org.html | head -n 1
...
Original HTML content file:
… (insert happy here)
Hash string:
...
If the SHA256 hash strings match, you’ve successfully verified that your BitAddress.org HTML file is an authentic copy.
Linux command to verify
Here’s a Linux command to help you verify the authenticity of your BitAddress.org HTML file using sha256sum and compare it with the original contents:
$sha1sum bitaddress.org.html | head -n 1 && cat <(echo "$(( $(sha256sum bitaddress.org.html) | head -n 1))" > /dev/null)
This command downloads the SHA256 hash string, prints it to the console using head -n 1, and then uses cat to redirect its output to a file. The $( ... ) syntax is used to execute the result of sha256sum bitaddress.org.html as a shell command.
If the contents match, this command should print nothing. If there’s any discrepancy, you’ll notice an error message indicating that the SHA256 hash string does not match the original contents.
Note: This method assumes that your BitAddress.org HTML file is stored in the same directory as the script and has a .html extension. Also, keep in mind that this method only checks if the SHA256 hash string matches the original contents; it doesn’t verify whether you used the correct version of BitAddress.org.
Hope this helps! Let me know if you have any further questions or concerns.
