Certifying HTML snippits inside your own content
If you have a webpage that you have the power to edit, you can insert the following
code where you want the beginning and end blocks to go.
Before the text/html you wish to certify, put this code in your HTML:
<div id="blockcert">BlockCert BEGIN: <img src="https://blockcert.com/img/bc_begin.png">
At the end of the text/html you wish to certify, put this code in your HTML:
</div><img src="https://blockcert.com/img/bc_end.png"> BlockCert END.
<button onclick="blockCertVerify('')">verify</button><span id="blockCertResult"></span>
Once this code is embedded in your webpage, you will be able to click on the 'verify' button
which will take you to the BlockCert certification form. The hash of your content will
be pre-populated in this form. Look over the rest of the form and make sure it is correct,
then submit it.
Once the certification is completed you will get a transaction number. Put that number
inside the single-quotes in blockCertVerify('') in your file.
Once this is done your
content will verify.
You can format the lines/spacings around the tags as all leading and trailing whitespace
around the content is removed before computing its hash/digest.
Once the content is certified, you will not be able to change even one character inside
the content without altering the hash digest. (You are still able to modify the whitespacing
around the content)
