ABOUT HASH-MORPH

Hash-Morph appends 4 cryptographically random bytes to the end of any file, changing its SHA-256 fingerprint without altering the file's actual content. Due to SHA-256's avalanche effect, even a single bit change produces a completely different 256-bit digest. Images still render, documents still open, and executables still run. The appended bytes sit past the end of the file format's structure.

USE CASES

Break hash-based file tracking systems that correlate copies of the same file
Generate fresh fingerprints for privacy research or red-team exercises
Test forensic tools and intrusion detection systems that monitor file hashes
Create unique copies of identical files for version control or deduplication experiments

FREQUENTLY ASKED

Will the morphed file still work normally?+

Yes. Most file formats (JPEG, PNG, PDF, DOCX, ZIP, MP3) ignore data appended after the format's end-of-file marker. The 4 bytes are effectively invisible to any application that reads the file.

How does appending bytes change the hash so dramatically?+

SHA-256 processes the entire byte stream of a file. Adding even 1 byte changes the input, and the avalanche effect guarantees the output is completely different. There is no mathematical relationship between the original and morphed hash.

Is hash morphing legal?+

Hash-Morph is a privacy and research tool. Using it to circumvent DRM, tamper with evidence, or alter files in violation of laws or agreements is your responsibility. The tool appends data in a way that does not modify the file's functional content.
