An iOS enterprise certificate is a .p12 signing certificate issued under an Apple Enterprise Developer account, delivered with a .mobileprovision provisioning profile. Importing both into a signing tool lets you sign an IPA file and install it on an iPhone or iPad without the App Store.
The password for every certificate file on this page is nabzclan.vip.
Every certificate is tested against Apple once a day. A certificate marked Signed still works. Revoked means Apple has switched it off, and Expired means its validity period is over. Each card shows the status and when it was last tested. Revoked and expired certificates are not tested again because they cannot come back.
Apple revokes enterprise certificates that are used outside the organisation they were issued to. A revoked certificate cannot be reactivated and apps signed with it stop opening, so download a certificate that is marked Signed instead.
Several downloads can belong to the same organisation. Each version is a separate certificate file or provisioning profile, for example for a different app ID, issued to that organisation. The newest signed version is listed first and is the one the main Download button gives you.
Download the zip file, extract the .p12 and .mobileprovision files, import both into an IPA signing tool and enter the password nabzclan.vip. Sign your IPA with them and install the result on your device.
