About the Hash Generator
Compute cryptographic hashes of any text or file. All common algorithms are calculated at once — MD5, SHA-1, SHA-256, SHA-384 and SHA-512 — and you can paste an expected checksum to verify a download.
Everything runs locally in your browser — nothing you paste is sent to a server, so it is safe to use with API keys, tokens and private data.
How to use the Hash Generator
- Type text or choose a file.
- All hashes are calculated instantly.
- Paste an expected hash to compare, or copy any result.
Frequently asked questions
Which hash should I use?
Use SHA-256 or stronger for anything security-related. MD5 and SHA-1 are broken for security purposes but are still used for simple checksums.
Can a hash be reversed?
No. Hashes are one-way functions. However, short or common inputs can be found with lookup tables, which is why passwords need special slow hashes such as bcrypt or Argon2.
How do I verify a downloaded file?
Choose the file, then paste the checksum published by the developer into the “Compare” box. A match confirms the file was not corrupted or altered.
