## Description

Android Backup Extractor is a software utility designed to manipulate and transform backup files created via the Android Debug Bridge. It functions as a decryptor and repacker that converts these backups into readable formats for manual data extraction.

The tool enables the decryption of protected backup archives using a known password, allowing for the recovery of mobile application data. It also provides the capability to compress directories back into backup archives that are compatible with specific legacy device versions for restoration.

The project covers archive conversion, extraction, and packing processes. It transforms encrypted or compressed backup files into standard archive formats to facilitate data inspection.
