Hash Generator
Generate SHA-256 hashes from text using browser crypto APIs.
Create a lowercase hexadecimal SHA-256 digest from the exact text you enter, using the browser Web Crypto API.
How to use this tool
- Enter the text to compare or record.
- Select SHA-256.
- Copy the 64-character hexadecimal output.
- For a comparison, hash the other text using exactly the same characters and whitespace.
Ways to use it
- Compare text values
- Check whether two separately supplied text values produce the same SHA-256 output.
- Prepare an integration example
- Create an expected SHA-256 value for documentation or a test fixture.
SHA-256 notes
- The tool hashes text only and outputs lowercase hexadecimal SHA-256.
- Whitespace, line endings and character changes alter the result. The tool does not trim or normalise the input.
- A hash is not encryption and this page does not verify file checksums, signatures or passwords.
Common questions
Why did a small edit change the hash?
SHA-256 hashes the exact input, including spaces, line breaks and other characters.
Can I hash a file?
No. This tool accepts text input only.
Is a hash the same as encryption?
No. A hash is a one-way digest, not a method for keeping a value secret.
