How we handle your data →How to use this tool
- Paste the exact text whose digest you need.
- Generate the digest of its UTF-8 bytes.
- Compare all 64 hexadecimal characters; check whitespace if digests differ.
An example you can verify
Compare the digest of exact text to detect differences between copies.
Example input
abc
Expected result
ba7816bf8f01cfea414140de5dae2223b00361a396177a9cb410ff61f20015ad
A space or line break changes the digest. This is SHA-256 of UTF-8 text, not file verification or encryption.
Settings and limits
The hash covers all UTF-8 bytes, including spaces and line breaks, using Web Crypto. The result contains 64 hexadecimal characters.
Frequently asked questions
Can I decrypt SHA-256 or store passwords with it?
SHA-256 is a hash, not reversible encryption. Password storage requires a specialized salted, cost-based algorithm rather than this simple hash.
