Hash Generator
Calculate MD5 and SHA hashes of text or a file. This tool runs 100% in your browser — nothing is uploaded or saved, which is exactly what you want for hashes.
Drop a file here to hash the file instead, or
How to use
- Type or paste text — MD5, SHA-1, SHA-256, SHA-384 and SHA-512 hashes update live.
- Or drop a file onto the box (or choose one) to hash the file contents instead.
- Click the Copy button next to any hash to copy it.
Tips
- Hashes are one-way: you cannot turn a hash back into the original text.
- Compare hashes to check file integrity — if a single character changes, the whole hash changes.
- SHA-256 or stronger is the safe choice for security; MD5 is fine only for quick checks, not passwords.
Frequently Asked Questions (FAQ)
Which hash algorithms are supported?
MD5, SHA-1, SHA-256, SHA-384 and SHA-512; hashes update live as you type.
Can I hash a file instead of text?
Yes — drop a file onto the box or choose one to hash the file contents.
Is my data uploaded?
No — it runs 100% in your browser; nothing is uploaded or saved.
Which algorithm should I choose?
SHA-256 or stronger for security; MD5 is fine only for quick checks, not passwords. Hashes are one-way — you cannot turn a hash back into the original text.
