iPhone certificate revoked?
When a signing certificate is revoked, apps that worked yesterday can suddenly fail to verify, install, or open. A fresh certificate package is usually the fastest path back.
Signs your certificate is no longer trusted
- Installed apps stop opening and show a verification message.
- Newly signed IPAs fail even when the password is correct.
- ESign, Feather, or another signer imports the files but installs still fail.
- A previously working install link no longer verifies on iPhone.
Before you buy again
- Check that the UDID you used is the exact device UDID.
- Confirm the .mobileprovision file belongs to the same certificate package.
- Try signing one known-good IPA to rule out a broken app file.
- If the certificate is revoked or expired, use a fresh package.
Frequently asked questions
Can a revoked certificate be repaired?
No. A revoked certificate cannot usually be made trusted again on iOS. The practical fix is a new working certificate and matching provisioning profile.
Will my old signed apps work again?
Apps normally need to be signed again with the new certificate files before they can install or open reliably.
What files do I receive?
CertDrop delivers the .p12 certificate, .mobileprovision profile, certificate password, and an install/download page.
