title: Fastlane: cannot use p12 file generated by "match" command
body: <p>I am configuring Fastlane and their <code>match</code> command to generate my Certificates and provisionings. All files are stored in a private github repo as recommended in the fastlane docs.</p>
  
  <p>All worked properly, certificates and provisionings were generated and stored in my private repo, including the p12 file for the certificates.
  But when I try to download this p12 file (to run my app in Xcode) it seems to be encripted. </p>
  
  <p>The <code>match</code> command encripted the p12 before uploading it to github, so the question is: </p>
  
  <p>--> How can I download and decrypt the p12 file generated by <code>match</code> command in my private repo??</p>
