Compute File Hash (FileReader)
This page implements a Javascript hash calculator for files. Local files do not need to be uploaded to server. This is based on HTML5 FileReader object (example) so binary files could be computed possible locally. Compute File Hash locally and fast for the following Hashes: CRC-32, MD5, SHA1, RIPEMD-160, SHA256, SHA512, SHA3-224, SHA3-256, SHA3-384, SHA3-512
Please note that you files will NOT be uploaded and your data remain safe locally.
- All computation are done locally within your HTML browser.
- File Hashes can be used to verify the data integrity/identify e.g. game patches, virus identification
- It is possible for hash collision to happen (two different files have the same hashes), but very unlikely.
- If the downloaded files have different hashes than given, please do not open!
- Maximum supported local file size = 3G (1024 * 3M).
If you want to MD5 hash string, you can use this online MD5 Hash Tool with API support: Unicode-String/Text MD5 HASH Calculator (Ajax Javascript)
