Hi, I have just re-installed Cydia on my iPhone 4 running 7.1.2 for the first time in about a year and it's saying "Unable to Load (The certificate for this server is invalid.

Https://cydia.saurik.com/ is the only official cydia website. Source: over 2 years ago

The site you linked to (hxxps://cydia-app.com/) is unofficial, links to piracy and spyware sites, and should not be trusted. The official Cydia site is http://cydia.saurik.com/ but it doesn't include much information about Cydia and jailbreaks. To find out what jailbreaks are available for your device, check the r/Jailbreak wiki. (https://www.reddit.com/r/jailbreak/wiki/ios/canijailbreak). - Source: Hacker News / about 3 years ago
