Which certificate files do ESign and Feather need?
For iPhone signing, ESign and Feather use the same three pieces: a .p12 signing certificate, the .p12 password, and a matching .mobileprovision profile containing your device UDID. CertDrop delivers all three together for $8 so you can import the package into either compatible signer on the registered device.
What a .p12 certificate is
- A .p12 file stores the signing certificate used by IPA signing tools.
- For iPhone sideloading, the .p12 must match the provisioning profile and your device UDID.
- CertDrop sends the .p12 file with the password needed to import it into supported signing tools.
What CertDrop includes
- The .p12 Apple Developer certificate file
- A matching .mobileprovision profile for your device
- The certificate password
- A private download page sent to your email after payment
Before you order
- Make sure your iPhone or iPad UDID is copied correctly.
- Use the same device UDID you plan to install signed apps on.
- If you are using ESign, Feather, Scarlet, or another signer, import both the .p12 file and mobileprovision profile.
Get a P12 certificate without a computer
You can complete the CertDrop flow from your iPhone or iPad. Use the free Get UDID tool in Safari, order the device-matched package, then import the delivered .p12 and mobileprovision files into a compatible on-device signer such as ESign or Feather. A Mac or PC is not required for that workflow.
Upgraded to an iPhone 18 Pro or Pro Max? The new phone has its own UDID, so use a certificate package prepared for the new device. See the iPhone 18 Pro / Pro Max certificate page.
