Calculate SHA-256, SHA-384 or SHA-512 for text

Developers and security teams use Text fingerprint when preparing a check, a local test or integration data.

Calculate SHA-256, SHA-384 or SHA-512 for your text and get a fingerprint ready to copy or compare. Use it for free in your browser, with no account required.

How to use

Choose the fingerprint algorithm among SHA-256, SHA-384 and SHA-512 for your project requirement.
Type or paste the exact text whose fingerprint you want to compute, without changing spaces or line breaks.
Run the calculation to obtain the character string that matches the entered content.
Copy the displayed fingerprint so you can compare it or keep it in your notes.
Erase the field before handling another text if you do not want the previous entry to remain visible.

Example

A developer may enter a short configuration string to check that a locally computed fingerprint matches the value expected by the team. The result appears in the dedicated area and is used for comparison, without revealing the original text or sending it elsewhere.

Limits and formats

This tool computes a fingerprint for text; it does not hash files or folders.
A fingerprint is not encryption: it does not allow you to recover the original text.
Three algorithms are offered; use the one required by your procedure or technical compatibility.
An identical fingerprint alone does not prove that content is safe or authentic.
The slightest change in the text, even a space, produces a different fingerprint.

Where processing happens

The fingerprint calculation takes place entirely in your browser. The entered text and the selected algorithm are processed locally, and the result appears without being sent or stored. Nothing leaves the page during the operation, even if the text is long.

Frequently asked questions

What is the difference between SHA-256, SHA-384 and SHA-512?

They are three fingerprint algorithm variants offered by the tool. The choice often depends on a technical requirement or compatibility with the system that will use the value. Pick the one your procedure or team asks for.

Can I recover the text from the fingerprint?

No. A fingerprint is designed to be non-reversible: it is used to compare or verify, not to retrieve the original content. Keep the original text separately if you need it later.

Is this suitable for storing a password?

Not directly. A simple fingerprint calculation is not enough to protect a password. For real password storage, follow dedicated authentication and key derivation practices with suitable parameters.
