As described in https://developer.android.com/studio/publish/app-signing#signing-manually I try to sign an app in git bash on windows 7.

I generate a keystore with

keytool -genkey -v -keystore my-release-key.jks
-keyalg RSA -keysize 2048 -validity 10000 -alias my-alias

this should use the default keystore type which should be fine.

Then I run zipalign

zipalign -v -p 4 my-app-unsigned.apk my-app-unsigned-aligned.apk

which gives "Verification succesful" (with one s)

and finally I run apksigner which gives me the error:

"C:....apksigner.bat" sign --ks my-release-key.jks --out my-app-release.apk my-app-unsigned-aligned.apk

Keystore password for signer #1:

123456

Failed to load signer "signer #1"

java.io.IOException: Invalid keystore format

I also tried different storetypes like pkcs12 which is not supported at all (gives: java.io.IOException: parseAlgParameters failed: PBE AlgorithmParameters not available)

So my question is how to find out the right storetype? I din't find anything about this in the help nor the internet.
