title: How to generate p12 certificate with 100 years validity using flash builder
body: <p>I am trying to upload debug version in google play store and i am getting this error </p>
  
  <p>Upload failed</p>
  
  <p>You uploaded an APK signed with a certificate that expires too soon. You need to sign your APK with a certificate that expires farther into the future.</p>
