AAPR will aim at being a password recovery utility for RAR and ZIP files encrypted using the AES encryption scheme. However, in its first release, it only support AES encrypted RAR (i.e. RAR v3+), that have encrypted file names. If you try to open a RAR file in Winrar and it does not ask you straightaway for a password and you can see the names of the encrypted files, this utility cannot help you, yet.
