Cannot recover key [duplicate]

Question

I published the first version of my app in Play Store two days ago. I used a key with a known alias and password.

Then, I changed the name of my app in eclipse, just changed one letter. Now, I want to export version 2 in eclipse, try use the key from the first time and enter alias and passwort. I´m sure they are correct!!

On the last step, Eclipse tells me "Cannot recover key". I tried it with a new one but then the Play Store shows an error. What can I do??

EDIT:

Like you see in the second image abobe, it MUST be the right password because otherwise the alias would not be in the dropdownbox. Also the second password is correct, it´s a copy from the first. I only have one alias!

Destination APK file-link in the last picture doesn´t matter right?

Answer 1

Solution: The KeyStore password and The Key password should be the same.

Changing both passwords using keytool

Change KeyStore password

keytool -storepasswd -new %newpassword% -keystore %YourKeyStore%.jks 

replace %newpassword% with your actual password, same with YourKeyStore

Change Alias key Password

keytool -keypasswd -alias %MyKeyAlias% -new %newpassword% -keystore KeyStore.jks 

Note: supply old passwords for both keystore and alias when asked for them

Answer 2

If you have special characters in you passwords use this tool to change it:

I've tried the commands on Windows and it didn't work(probably because of the special characters).
