Not able to sign AAB file

[Svein-Tore]

Hi!
I want to upload my app to google play, but I'm not able to fix it . I have followed the tutorial found here: Tutorial for signing an AAB file

But I can't get it work. The tutorial says:

• Step 5: Copy the following code and paste it into the text editor:

java -jar Path to pepk.jar --keystore=Path to keystore --alias=Enter the alias here, usually applications built in App Inventor should have the alias: androidkey --output=The path to export the private key file (what needs to be uploaded to Play App Signing) It should be a zip file! --encryptionkey=Enter the sequel here (this is already entered in what you copied from the Play App Signing)

I have tried to find out how this should be done. I end up with something like this:

java -jar pepk.jar --keystore=android.keystore --alias=androidkey --output=output.zip --include-cert --rsa-aes-encryption --encryption-key-path=encryption_public_key.pem

android.keytore is downloaded from app inventor. encryption_public_key.pem is from google play console.

When I run this command in console I get the following:

Enter password for store 'android.keystore':
Enter password for key 'androidkey':
Error: Unable to export or encrypt the private key
java.security.NoSuchAlgorithmException: Cannot find any provider supporting RSA/NONE/OAEPWithSHA1AndMGF1Padding

at com.google.wireless.android.vending.developer.signing.tools.extern.export.ExportEncryptedPrivateKeyTool.main(ExportEncryptedPrivateKeyTool.java:165)

I have used android for both password for store 'android.keystore' and for password for key 'androidkey' as said in the toutorial.

Any suggestions?

Tutorial for signing an AAB file

Hello everyone!
