Apple Encrypted Archive
From Just Solve the File Format Problem
(Redirected from AEA)
Apple Encrypted Archive is a proprietary file format that can compress, encrypt, and sign files. The decrypted and decompressed payload often contains an Apple Archive.[1][2]
iOS 18 firmware images have started to use AEA-encrypted DMG files.[3]
