What is FHash?
fHash is an open source command line program and library for computing and verifying hash sums of files. It was designed as an alternative to other file hashing tools like md5sum or sha1sum. Some key features of fHash include:
- Supports common hash algorithms like MD5, SHA1, SHA256, SHA512, CRC32
- Can recursively hash all files in a folder and subfolders
- Command line interface as well as GUI for interactive use
- Portable Windows executable with no dependencies
- API and library for integration into other applications
- Output hash sums in multiple formats like SFV or JSON
- Detect duplicate or similar files by comparing cryptographic hash sums
- Verify integrity of files by recomputing and matching hashes
- Small footprint and high performance even for large files
fHash is commonly used for digital forensics, data deduplication, file synchronization, and ensuring data integrity. It runs on Windows XP through Windows 10 and Windows Server. The open source code is written in C and available on GitHub under the MIT license.
