RIPEMD-256 File Hash
Calculate a RIPEMD-256 file hash or HMAC from a local file or URL without uploading local files. Read more
What is RIPEMD-256?
RIPEMD-256 is an optional longer-output extension of RIPEMD-128. The authors’ specification states that the longer result was not intended to provide a larger security level. This calculator processes raw file bytes for compatibility with systems that explicitly use RIPEMD-256.
How to use this file hash calculator
Choose a local file or URL and output format. Keep HMAC disabled for a plain checksum; enable it only for a defined shared-key use. Local bytes and keys remain in your browser. URL processing requires CORS.
Result example
A file containing exactly abc produces afbd6e228b9d8cbbcef5ca2d03e6dba10ac0bc7dcbe4680e1e42d2e975459b65 in Hex. Filename and metadata are excluded.
Important limitations
Its 256-bit output does not imply a higher security level than RIPEMD-128. A plain digest does not authenticate the file; HMAC depends on a secret key. Prefer modern checksums for new publication workflows.
Frequently asked questions
Why does my result differ from another tool?
Confirm the same raw bytes, RIPEMD-256 algorithm, and HMAC mode. If HMAC is enabled, key bytes must match too.
Can I use the result to verify a download?
Use it when an existing source explicitly supplies RIPEMD-256. For encoded text, use the RIPEMD-256 calculator.
