Free online tool
Generate SHA-256, SHA-384 and SHA-512 digests from text directly in your browser.
Tool workspace
Paste or enter the data you want to process, then run the tool.
Checking text fingerprints, validating deterministic hash output and learning how common SHA-2 hash functions represent input data.
The same text and algorithm always produce the same digest, but even a tiny input change produces a different result; hashing is not encryption.
A hash cannot be reversed to recover the original text, and this general-purpose tool is not a substitute for a dedicated password-hashing scheme such as a salted password KDF.
How to use it
Use the controls above, check the result, then copy or download it when available.
SHA-256 is a common general-purpose choice; use the algorithm required by the system or protocol you are working with.
Use this tool whenever you need: Checking text fingerprints, validating deterministic hash output and learning how common SHA-2 hash functions represent input data. It offers a fast, client-side workflow without sign-ups, installation or complex software.
Yes. All processing executes locally in your browser using client-side JavaScript. Your inputs, files and calculations remain private and are never uploaded to our servers.

Security utility
Choose an algorithm, enter your text, then generate a fixed-length digest locally.
Hashes are sensitive to every character, including spaces and line breaks.
Nothing is uploaded. The Web Crypto API performs the digest in your browser.
All options create hexadecimal SHA digests.
