FTK Imager

FTK Imager is a forensic imaging tool designed to create verifiable copies of evidence media and maintain chain-of-custody. It supports multiple image formats including RAW, E01, and AFF, and it can generate cryptographic hashes during imaging. The tool is intended for digital forensics investigators, incident response teams, labs, and consultancies that require reproducible evidence acquisition without modifying original media. By streaming data from the source to a destination, it minimizes risk to the evidence and provides traceable results suitable for court or audit.

Conceptually, imaging is performed as a read-only copy that computes hashes in parallel, optionally segments large images into manageable parts, and exports a manifest. If E01 is chosen, the tool writes EnCase-formatted segments along with metadata. Optional features such as compression and selective hash algorithms allow tailoring to project requirements. After imaging, a verification pass can recompute hashes on the destination and compare with the source to detect any divergence.

Beneficiaries include forensic labs, government agencies, security teams, and incident responders who must preserve integrity while accelerating casework. The unique value lies in multi-format support, built-in integrity verification, and the ability to produce structured manifests for evidence processing. Core capabilities cover input validation, streaming imaging, error handling, and detailed logging to support auditing and reproducibility. Use cases include acquiring a suspect drive for offline analysis, generating a forensics-ready image for court, or creating a portable analysis bundle with hashes. The tool is designed as a non-destructive acquisition utility, not a data-extraction or file-contents analysis tool.
