About the Hash Generator
A hash is a fixed-length fingerprint of text or a file: change one character and the hash changes completely. Generate MD5, SHA-1, SHA-256, SHA-384 and SHA-512 hashes to verify downloads, compare files or work with APIs.
When to use it
- Checking a downloaded file against the checksum published by its author
- Comparing two files without opening them
- Creating content hashes for caching or de-duplication
- Testing signature and hashing code
Tips for the best results
- Use SHA-256 or stronger for anything security-related; MD5 and SHA-1 are only for checksums
- Hashes are case-insensitive — uppercase and lowercase mean the same value
- For storing passwords, use a slow algorithm like bcrypt or Argon2, not a plain hash
How to use the Hash Generator
- Paste your input into the Hash Generator.
- The output is generated instantly in your browser.
- Copy or download the result.
