iReSign allows iDevice app bundles (.ipa) files to be signed or resigned with a digital certificate from Apple for distribution. This tool is aimed at enterprises users, for enterprise deployment, when the person signing the app is different than the person(s) developing it.
iReSign allows you to re-sign any unencrypted ipa-file with any certificate for which you hold the corresponding private key.
-
Drag your unsigned .ipa file to the top box, or use the browse button.
-
Enter your full certificate name from Keychain Access, for example "iPhone Developer: Firstname Lastname (XXXXXXXXXX)" in the bottom box.
-
Click ReSign! and wait. The resigned file will be saved in the same folder as the original file.
