I wanted to support app link feature for my android application and while using App-link Assitant tool in the android studio, and while signing the apk I was using my own generated *.jks file. I found there is a field SHA256_cert_fingerprint. I wanted to know what is the paramter involved in calculating SHA256_cert_fingerprint. I tried calculating using online SHA256 calculator with the following paramters separately but it was not matching with the SHA256 value shown in the image

  • *.jks
  • private key
  • certificate
  • public key
  • *.csr

Screenshot for the SHA 256 value calculated by android studio for implementing app link

Does anyone know what are the actual parameters involved in calculating SHA256_cert_fingerprint value? So, that again when I compute the hash through online SHA256 calculator, when compared with the image, I will get the exact match.

For the case of Android Apps, when we sign the app it can be signed through a Java Keystore file (*.jks) which contains the public/private key. So, now I tried to export the certificate using the command

keytool -exportcert –alias aliasname -keystore fileUsedToSignApp.jks -file outputFile.cer

Now, if we will compute the hash of the document outputFile.cer through some available online tool, it will be of the same value as shown in the screenshot (mentioned in the question) Reference: I got the command from the link
