hashdeep: Open Source Hashset and Fuzzy Hashing Tool
Hashset and fuzzy hashing tool for data matching, computer forensics and more, with support for multiple hashing algorithms.
What is Hashdeep?
hashdeep is an open source cross-platform software used to compute hash sets and perform fuzzy hashing for purposes like data matching and computer forensics. It is designed to integrate with other forensic tools.
Some key features of hashdeep include:
- Supports many common hashing algorithms like MD5, SHA1, SHA256, ssdeep, and others.
- Can match hashes even if there are minor differences between files using fuzzy hashing.
- Generates comprehensive reports detailing hash values and matches.
- Command line interface allows automation through scripts.
- Cross-platform - runs on Linux, macOS, and Windows.
hashdeep can help identify duplicated files and data even if there are small changes by matching fuzzy hashes. It generates detailed reports showing file hashes and matches between them. Overall, hashdeep provides an effective way to match data sets and identify similarities for purposes like forensics, data deduplication, and verification.
