How to Generate SHA-1, SHA-256, SHA-384, SHA-512 Hashes from Text
Free, step-by-step guide. No signup needed — everything runs in your browser.
1
Open the Hash Generator
Navigate to the tool. Browser-side hashing — no signup, no server.
2
Paste your input text
Drop any text into the input box: a password, an API key, a file’s contents, any string.
3
See all hashes at once
The tool computes SHA-1, SHA-256, SHA-384, and SHA-512 in parallel. Results appear as you type.
4
Copy the hash you need
Click any hash row to copy it to your clipboard. The hex digest is ready to paste anywhere.
Tips for best results
- SHA-256 is the modern default — used in TLS certificates, Bitcoin, JWT signing, and most checksum scenarios.
- SHA-1 is broken for security but still used for non-security checksums (Git commit IDs, legacy systems). Do not use it for passwords or signing.
- MD5 is intentionally excluded — it is cryptographically broken and should not be used. If a system requires MD5, push to upgrade.
- Hashes are one-way: you cannot recover the original input. Salt + hash + slow KDF (bcrypt, argon2) is the right pattern for passwords — plain SHA-256 is not.
- For file verification: hash a downloaded file’s contents and compare against the published hash on the release page.
