This webpage lists all the certificates' serial numbers and checksum we have generated for you. It can be used to verify your certificate's legitimacy. You can find your certificate's serial number at the top-right corner of your certificate.
Each listed serial number is a unique name for each certificate. Each listed checksum is an SHA-256 hash of the original certificate. If you modify the certificate using say Inkscape, the hash will change and the certificate will be invalid. But, renaming the certificate filename will not change the hash. The checksum is used to verify the authenticity of the certificate.
There are two ways you can verify your certificate:
1) You can generate the checksum of your certificate by yourself using
- In Mac OS:
shasum -a 256 <filename> - In Linux:
sha256sum <filename> - In Windows: here
where <filename> is the filename of your certificate (for e.g. Stephen-Hawking-7sgg8mT-2s440.pdf), and compare with the checksum we listed on the respective web pages.
2) The checksum can also be verified using the following command:
- In Mac OS:
shasum -a 256 -c checksum.txt - In Linux:
sha256sum -c checksum.txt - In Windows: here
where checksum.txt should have a checksum hash, two spaces and then your certificate filename. The checksum is listed on the respective web pages. You need to copy it to checksum.txt and replace <fullname>-SerialNumbers.pdf with your certificate filename.
For example,
9esde6sd1c090305223da0833c249766a64cf19cffeb220e0f03bbfa9369bab208 Stephen-Hawking-7sgg8mT-2s440.pdf
where checksum hash is 9esde6sd1c090305223da0833c249766a64cf19cffeb220e0f03bbfa9369bab208 , filename is Stephen-Hawking-7sgg8mT-2s440.pdf, and the serial number of the certificate is 7sgg8mT-2s440.
