Hi all,
As a newbie, I struggled to run the docker image and the python program to create a valid certificate and to understand each block of data. It took me a while to understand that anchoring the merkle root in a blockchain is optional. This easy to use code simply creates the JSON file that passes remote validation. Also I did not find a Java project with POJOs for all JSON elements, so I created one. This also uses URDNA2015 for JSON-LD so that the SHA-256 created matches with python and js.
Hence, I created a simple Java program with java objects for each block that can be easily converted into final JSON.
Goal
Build a JSON file in Java using java objects, use default input data, generate local hash and build signature block. Pass remote validation in blockcerts.org by inputting the generated json file.
Steps
- git clone/Download
- import/open project in Eclipse
- go to CreateCertificate.java file
- “Run” as Java application
- Output JSON file will be created in the eclipse-workspace project directory and filename will be shown in the console
- go to blockcerts.org in the browser
- Click choose json file and pick the newly created .json file
- blockcerts will show “This Mocknet credential passed all checks”
- That’s it. Change the default values and see how it affects validation
