Before you start
What you need
Text to fingerprint, a SHA-2 algorithm, and hexadecimal or Base64 output.
Developer & Data
Hash Generator
Create SHA-256, SHA-384, or SHA-512 digests from UTF-8 text with Web Crypto.

No black box
How this tool handles the input
The browser encodes source text as UTF-8 and passes it to the selected Web Crypto digest algorithm.
What you get
What the page gives back
A deterministic digest ready to compare or copy.
Keep in mind
Use the result responsibly
A plain fast hash is not suitable for password storage. Use a password-specific KDF with salt and policy on the server.
Practical uses
Where this tool earns its place
- Compare a text fixture across systems.
- Create an integrity fingerprint for a known string.
- Verify expected SHA-2 encoding output.
Verified data boundary
Source text stays on this page.
The published contract marks these tools as client-only processing. Nirmion uses the API only to confirm that this workspace is enabled in MySQL; source values and results are not sent to Flask.
