TL;DR — generate SHA‑256 (and more), compare, copy, and export—right in your browser
Paste text or drop a file. Get SHA‑1, SHA‑256, SHA‑384, SHA‑512 (plus optional MD5) in Hex or Base64. Paste a known checksum to see match / no match, then copy or download a TXT report. Everything is computed locally for privacy.
Hash Generator — quick checksums for files and text
Need to verify a download, prove a payload hasn’t changed, or generate a checksum for a handoff? This online hash generator gives you fast, reliable digests with zero setup. Type or paste text into the editor—or simply drag a file into the page—and we’ll compute SHA‑1, SHA‑256, SHA‑384, and SHA‑512 instantly. For legacy systems that still expect it, you can enable MD5 too. Choose Hex or Base64 output, and switch Hex to Uppercase when you need to match CLI tools or release notes that publish uppercase digests.
The built‑in Compare box speeds up verification. Paste the checksum a vendor provides—usually a SHA‑256—and each algorithm row will light up with a clear match or no match label. It’s an easy way to confirm file integrity before you install software or share artifacts with a team. When you’re done, copy any value, copy everything at once, or download a neatly formatted TXT record that includes all algorithms.
Everything happens client‑side. Your text and files never leave the browser, which makes this tool safe for internal notes, log snippets, or private builds. If you actually need reversible protection rather than hashing, use Secure Text Encryptor instead. To generate strong random inputs for IDs or salts, try the Password Generator. For quick cleanup before hashing (remove odd whitespace, normalize line endings), open Advanced Text Cleaner or make precise edits with Find & Replace.
When to use which option
SHA‑256 is the modern default for integrity checks—use it to validate installers, archives, and assets you download from the web. SHA‑512 offers a longer digest and is common in security‑conscious environments. SHA‑1 and MD5 remain in old documentation and workflows; they’re convenient for compatibility but should not be used for security‑critical decisions. Pick Hex if you want easy visual comparison or need to match command‑line tools; pick Base64 if you’re moving values through JSON or systems that prefer shorter, printable strings.
Reminder: hashing is one‑way. You can’t convert a digest back into the original text or file contents. If you need to protect data but keep the option to decrypt it later, use encryption—never a hash.

Tips
- Vendors usually publish a SHA‑256 checksum—paste it into Compare to verify downloads.
- When a hash doesn’t match, check for extra spaces/newlines and make sure your output format matches (Hex vs Base64).
- Use Uppercase if you need to match tools that print uppercase Hex (some CLIs and release notes do).
- For sensitive workflows, avoid MD5 and SHA‑1; prefer SHA‑256 or stronger.
