Hash Generator (SHA-1 / SHA-256 / SHA-384 / SHA-512) vs Online hash generators (e.g. md5hashgenerator.net-style sites)
Many online hash sites compute MD5/SHA hashes server-side, which means your input string is sent to their server. Gera Tools computes SHA hashes in your browser using the Web Crypto API (crypto.subtle.digest), so the text you hash never leaves your device.
If you are hashing anything sensitive — a password, a token, a secret string — use a tool that computes locally. Gera Tools uses the browser's Web Crypto API so your input is never uploaded. If you specifically need MD5, a dedicated MD5 tool will cover that legacy case.

Side-by-side comparison
| Feature | Hash Generator (SHA-1 / SHA-256 / SHA-384 / SHA-512) Gera Tools | Online hash generators (e.g. md5hashgenerator.net-style sites) md5hashgenerator.net |
|---|---|---|
| Price | ✓ Free | ✓ Free |
| Computation location | ✓ In your browser via Web Crypto (crypto.subtle.digest) — input never uploaded | ≈ Many single-page hash sites compute server-side; confirm before hashing sensitive input |
| Algorithms | ✓ SHA-1, SHA-256, SHA-384, SHA-512 | ✓ Often MD5 plus some SHA variants |
| Account required | ✓ No account | ✓ Usually none |
| Works offline after load | ✓ Yes — Web Crypto runs locally with no network | ≈ Server-side tools require a round trip |
Comparison based on each tool's publicly stated, free-tier behaviour at the time of writing.

FAQ
Is the Gera hash generator client-side?
Yes. It uses the Web Crypto API (crypto.subtle.digest) in your browser, so the text you hash is never sent to a server. You can verify this in the Network tab.
Does it support MD5?
No — it provides the modern SHA family (SHA-1, SHA-256, SHA-384, SHA-512). MD5 is cryptographically broken; if you need it only for a legacy checksum, use a dedicated MD5 tool.
Why does hashing location matter?
If a tool hashes server-side, the input you type is transmitted to their server. For passwords or secrets, prefer a client-side tool like Gera Tools that computes the hash locally.
