# Generate Text Hashes

> Safe to paste production secrets, tokens, or proprietary payloads — hashing runs through the Web Crypto API in your tab, so input and digests never touch a server. MD5, SHA-1, SHA-256, SHA-384, and SHA-512 compute in parallel and update live as you type. Copy any digest with one click.

## How it works

1. **Enter text** — Type or paste the text you want to hash
2. **View hashes** — MD5, SHA-1, SHA-256, and SHA-512 hashes are computed in real time
3. **Copy** — Copy any hash value with one click

## FAQ

### Which algorithms are supported?

MD5, SHA-1, SHA-256, SHA-384, and SHA-512.

### Can I hash files?

Use the File Hash Calculator tool for file hashing. This tool is for text input.

### Is it safe to paste production data?

Yes. Hashing runs in your browser via the Web Crypto API. Inputs and digests stay on the page; nothing is logged, sent, or cached server-side. Safe for credentials, tokens, and proprietary payloads.

## Tips

- **Safe for credentials and tokens** — Hashing runs locally through the Web Crypto API. Input text and digests never leave the page, so production secrets can be pasted without a server round-trip.
- **Five algorithms compute in parallel** — MD5, SHA-1, SHA-256, SHA-384, and SHA-512 are all generated from a single input. Copy any digest with one click.
- **Use the file tool for binaries** — This tool hashes text input only. For checksums on downloaded files or ISOs, use the File Hash Calculator instead.

## Privacy — what we do not do

This tool runs entirely in the browser via WebAssembly. Your file never reaches a Loft Tools server. Specifically:

- **No upload.** The file bytes load into the browser tab's memory and process on your own CPU. Open DevTools → Network and observe zero outbound requests carrying file data while Generate Text Hashes runs.
- **No AI training on your file.** Loft does not train models. We could not train on a file we cannot see.
- **No content scanning.** No virus, copyright, or content-moderation pass against your file. The bytes are not accessible to us.
- **No server-side log of file contents, filenames, or EXIF metadata.** Cloudflare edge captures URL and truncated IP for abuse defense (standard CDN behaviour). Cloudflare Web Analytics records anonymous page hits, no cookies, no PII. Nothing about your file content reaches any log.
- **No retention.** Close the tab and the file leaves browser memory. No backups exist on our side because no copy ever existed on our side.
- **No account.** No email, no signup, no auth, no telemetry tied to you.
- **Offline-capable after first visit** (PWA). Once you've loaded a tool, it caches; later sessions work without internet. For high-sensitivity files, run the tool once online to warm the cache, then disconnect before processing.

Compare with upload-based services: each transmits your file to a processing server. Even over HTTPS, each has logs, retention windows, and subpoena exposure. Loft has none of these because the server architecture does not include your file.
