SHA-256 hash
Calculate a SHA-256 fingerprint of UTF-8 text.
Type or paste text and run the tool to encode it as UTF-8 and calculate a SHA-256 digest using Web Crypto. The result is a 64-character lowercase hexadecimal fingerprint. The exact input matters, including spaces, letter case and line breaks.
How to use
- Enter your text, values, or image.
- Adjust the options and run the tool.
- Copy or download your result.
Limitations and details
This hashes text rather than files, and unsalted SHA-256 is not a password-storage scheme or reversible encryption.
