libqcow is a library designed to access QEMU Copy-On-Write (QCOW) image file format for digital forensics and analysis purposes. The library provides read-only operations for QCOW versions 1, 2, and 3, enabling investigators to examine virtual machine disk images without modification. It supports zlib (DEFLATE) compression decompression, AES-CBC 128-bit encryption handling, and backing file (differential image) processing. Currently in alpha development status, the library operates under LGPLv3+ licensing. The project includes API functions for file access and is working towards thread-safety implementation. Some features remain unsupported including LUKS encryption, data file handling, and in-image snapshots. The library serves as a foundation for forensic tools that need to analyze QEMU virtual machine disk images in investigations.
