The private key was not properly encrypted or is not a type of key we support

Question

When I upload my zip file in Google Play Console, it is not accepted. What did I do I see this notification?

The private key was not properly encrypted or is not a type of key we support.

Answer 1

Every time you open the page or maybe download the new PEM file it GENERATES A NEW ONE and apparently invalidating the old one.

So if you are struggling to create a private key and accidently press the button again, I think your old PEM file is not valid anymore.

So the conclusion is: you have to do it in one go.

Answer 2

To generate private encrypted key use below commands in terminal (Mac)

java -jar /Users/jhon/Documents/pepk.jar --keystore=/Users/jhon/Documents/Keystore/mykeystore.jks --alias=ka0 --output=/Users/jhon/Documents/SignedApk/TestApp/encryptedkey --rsa-aes-encryption --encryption-key-path=/Users/jhon/Documents/SignedApk/TestApp/encryption_public_key.pem

Answer 3

First, verify that encryption_public_key.pem is valid. Ensure that you didn't copy-pasted from another project.

Second, uploading the certificate is not intuitive. Once you uploaded (even without app publishing) the certificate is applied. Navigate to Setup ->App Signing, double check wether the certificate signature equals to the one you uploaded. If everything is correct - do not select Export and upload a key from Java keystore anymore option but Let Google manage and protect your app signing key (recommended) and upload app bundle (.aab) signed with your release or upload certificate. The Google will use provided keystore (that you also have) and sign the app

Answer 4

I also encountered this error, the reason is very simple but it took me a lot of time, private key file only need to upload once, instead the second upload will report this error, I have suggested Google to change this error description, too confusing.
