On-device processing means the input is handled by browser APIs on the device running this page. Closing or refreshing the page normally clears the active in-memory working session.

Calculate SHA-256, SHA-384 or SHA-512 fingerprints using the browser Web Crypto API.
How to use it
- Enter text or choose the supported input.
- Select a SHA algorithm.
- Generate and compare the hexadecimal digest.
Supported input
- Text encoded as UTF-8
- Algorithms SHA-256, SHA-384 and SHA-512
Worked example
Generate SHA-256 for a downloaded release note and compare it with the publisher’s trusted checksum.
Limitations
- A hash does not encrypt or hide input.
- A matching hash is useful only when the expected value comes from a trusted source.
Troubleshooting
- Confirm exact whitespace and line endings when hashes differ.
- Verify the selected algorithm matches the expected checksum.
Tool-specific questions
Can a hash be reversed?
Secure hash functions are one-way, though weak inputs can be guessed.
Is this suitable for storing passwords?
Password storage requires a salted, deliberately slow password-hashing scheme, not plain SHA.
Before you process
Can I use this hash generator online without uploading my input?
Yes. This tool is labelled On-device, so the selected input is processed in your browser and is not sent to a ForgeMyFile processing API.
What happens if the browser cannot process it?
The tool shows a readable error and stops. It does not silently fall back to a cloud upload.
Why can performance differ between devices?
The browser is doing the work locally, so speed and practical file size depend on available memory, CPU and browser capabilities.
