HMAC-SHA-256
Enter a secret to generate HMAC-SHA-256.
File SHA-256 checksum
Choose a file to calculate a browser-local SHA-256 checksum.
Files and inputs are processed in the browser only. Use a dedicated KDF such as bcrypt or Argon2 for password storage hashes.
Tool usage summary
Use it for download verification, release artifact comparison, text change checks, and checksum notes in documentation.
- Processing
- Text and files are calculated with browser-side crypto or local processing flows without requiring server upload.
- Example
- Select release.zip to create a SHA-256 checksum that can be pasted into release notes.
Quick answer summary
Hash Generator creates checksums such as SHA-256 from text or files for integrity checks.

What is this tool?
Hash Generator is a browser-first tool for convert text into SHA-1, SHA-256, SHA-384, or SHA-512 hashes. It fits into the developer workflow and keeps the main task on one page.
How to use it
- Enter the input
Paste or edit the value in the input area. Sample values are safe placeholders for testing the tool.
- Adjust options
Choose the mode, format, unit, or count that matches the hash, SHA-256, checksum task.
- Review the result
Run the tool, inspect the output, then copy or download it only when the result matches your expectation.
Examples

- Output
- Review the result in the browser.
Practical tips
- For large inputs, process the smallest useful sample first to keep the browser responsive.
- Ad slots are intentionally kept away from tool controls and result panes.
FAQ
What input should I use with Hash Generator?
Use values that match the hash, SHA-256 task, then adjust the visible options before running the tool.
Can I copy the Hash Generator result?
Yes. Review the output first, then copy or download it when the result matches your expectation.
Can I use Hash Generator on mobile?
Yes. The input, options, action, and result areas are designed to stack cleanly on small screens.
Will ads interrupt Hash Generator?
No. Ad slots stay outside the input, output, and primary action areas so the tool remains usable and policy-safe.
Can Hash Generator create file checksums?
Yes. It can create SHA-256-style hash values for text or selected files so you can verify integrity.
Are files uploaded to a server for hash calculation?
No. Text and files are calculated in a browser-local processing flow without server storage.
Is a checksum the same as password hashing?
No. Integrity hashes and password storage have different requirements; authentication systems should use salts and dedicated password-hashing algorithms.
