Before you start
- Use only data you are entitled to inspect, and avoid pasting live credentials into screenshots or shared notes.
- Decide where the final value will be stored before generating or copying it.
MV ToolsText tool
Online SHA Hash Generator
Generate SHA-1, SHA-256, SHA-384, and SHA-512 hashes for text or files directly in your browser.
Use a hash to compare bytes, not to hide a secret
Hash the exact downloaded file or exact text, then compare the complete digest with a value obtained from a trusted publisher or system.
- Runs locally. Text input is limited to 2 MB; file input is limited to 200 MB.
- Supports SHA-1, SHA-256, SHA-384, and SHA-512. Record which algorithm and output case the comparison source uses.
- A hash is one-way integrity data, not encryption, and it does not prove who created a file unless the comparison value comes from a trusted source.
Text, files, digests, copying, and downloads stay in the browser. Prefer SHA-256 or stronger when the trusted source specifies one.
How to Generate, Check, and Inspect Security Data LocallyTreat generated and decoded values as sensitive
Check the result
- Confirm the algorithm, character set, claims, or digest matches the system that will consume it.
- Verify expiry and issuer details for tokens, and compare hashes only from the exact same source bytes.
Know the limit: Decoding, generating, or hashing does not authenticate a token, recover a password, or replace a security review.
Online SHA Hash Generator for Text and Files
Generate SHA-1, SHA-256, SHA-384, and SHA-512 hashes locally in your browser for text, files, checksums, and integrity checks.
What This Tool Does
This browser-based tool uses the Web Crypto API to calculate hashes from text input or uploaded files and returns hexadecimal digest output.
Common Use Cases
- Generating SHA-256 hashes for test payloads
- Checking file digests before sharing or comparing files
- Creating hash values for logs, fixtures, scripts, or development workflows
How Data Is Handled
Hash generation runs locally in your browser. Text and files are not uploaded to the backend.
FAQ
Which hash algorithms are supported?
The tool supports SHA-1, SHA-256, SHA-384, and SHA-512 using the browser Web Crypto API. SHA-256 or SHA-512 are usually better choices for current workflows.
Does this support file hashing?
Yes. Files are read in your browser and are not uploaded to MV Tools.
Is a hash encryption?
No. A hash is a one-way digest, not reversible encryption.
