title: Check android keystore keypass for correctness
body: <p>I'm automating some things that involve the android keytool and jarsigner. The tool takes a keystore, the password for the keystore, the alias name, and the password for the alias / key, and I'm trying to find a way to explicitly check to see if the supplied password for the alias / key is correct.</p>
  
  <p>Any ideas? Also, I need to check it without a jar file to sign - getting that file in my context is lengthy, so I want to abort sooner rather than later.</p>
