I’ve donwloaded diaspora form github https://github.com/diaspora/diaspora and there is only fingerprint at the bottom of the page and if you click it whole key block will appear. So I copy all the key block paste it in to kwrite ande save it as diaspora-develop.zip.sig but when I did Code:
That fingerprint was merely a fingerprint, not a gpg signature.
I’m not quite sure what you downloaded. I did try downloading “develop.zip”. I did not see any indication that it is signed.
On my reading of the web page, the fingerprint is intended only to identify the key that you should use if you want to send them encrypted email about a security issue.
