How to decrypt an .aea package
On macOS 13 or later, Apple's own aea tool does it. Each row's Key button copies that package's key. For the newest package, the whole command is:
aea decrypt -i d1dc5aa634ba869e7243212d6e93f892dcb110bc726f1679451b9a6493006f2f.aea -o d1dc5aa634ba869e7243212d6e93f892dcb110bc726f1679451b9a6493006f2f.aar -key-value 'base64:L1TZagDYsHQlF6ELYkB02swjSL2DtTY5zmAOLWacadI='Specifications
