What is an OPENCERT file?

OPENCERT files mostly belong to OpenCerts Viewer. OPENCERT files are digital certificates saved in a JSON format. They carry verified information such as the issuer, recipient, and digital signature.
These files are used in educational and professional settings for verifying credentials. They are issued by platforms like OpenCerts Verifier, OpenCerts Viewer, and OpenCerts Wallet.

They use an open standard that makes it simple to exchange certificate data.

The JSON format allows for both human readability and easy machine processing.

Some implementations may involve blockchain or cryptographic methods to secure the certificate.

For more details on the standard, visit the OpenCerts website.
FilExt.com tip: If you have an OPENCERT file, you can open it with any text editor to view its JSON structure, or use a dedicated viewer designed for digital certificates. Be careful not to modify the file as its integrity is key to its verification.

An OPENCERT file predominantly uses a uniform format. But the following two file formats are common:

99% of all OPENCERT files internally utilize the JSON file format. JSON (JavaScript Object Notation) is a lightweight data−interchange format. It is easy for humans to read and write. It is easy for machines to parse and generate. These files are text files and can therefore be read using a text editor. The file size is in the range of 4 KB to 140 KB. The file type was developed only in the last few years. Certain words are almost always found in the files, such as "data": {, string, name, "version": "https://schema.openattestation.com/2.0/schema.json", opencerts and "$template": {. A usual file name is CERTIFICATE OF COMPLETION.opencert. Such OPENCERT files store data about certificate, completion, diploma, gceo, management, cert, safety, engineering, transcript and xxxxxf.

All other OPENCERT files (1%) have no consistent format. These files sometimes refer to xxxxxd, cambridge, education, singapore, general or level. Just click the "Choose your .opencert file to view" button on this page to find out what your OPENCERT file is.
