Convert keystore from SHA1 to SHA256

Hello,

According to https://software.intel.com/en-us/forums/intel-xdk/topic/622990 the new XDK system creates SHA256 keystores.

But HOW can I convert my old XDK SHA1 keystore to a SHA256 one ?

My problem is that Google requieres the SHA256 signature for AppLinks (https://developer.android.com/training/app-links/index.html#web-assoc) and I can't retrieve it

Thanks for the help!

You can download your certificate from the "account settings" tool and do anything you like with it from there. Search StackOverflow for tools on how to extract information from the certificate or modify it. See the image below for help on locating the account settings:

Thank Paul,

I've already downloaded my cert and extracted the informations, but i can not found the SHA256 signaure (only MD5 and SHA1 are present), my question was how to generate/modify that signature without changing my cert for Google Play.

And I can't found any information about that nowhere... The only information i got is, not possible (https://guardianproject.info/2015/12/29/how-to-migrate-your-android-apps-signing-key/)

Any help ?

[EDIT]

I finaly got my informations, and for the record you need java 1.8 to get the SHA256 signature when using

keytool -list -v -keystore myapp.keystore

By default, apple java version is 1.6 and you only got MD5+SHA1 information. So just need to download the Oraclle Java JDK 8 to get the informations, no need to manipulate the cert.

regards
