About SHA-256 hashing
This SHA-256 hashing tool generates a 256-bit digest (64 hex characters). SHA-256 is a common choice for integrity checks, signatures, and secure identifiers.
How to generate
- Choose Input Encoding (UTF-8 recommended).
- Choose Output Encoding (Hex lower is common).
- Enter text and click “Create SHA-256 Hash”.
- Copy the result for integrity checks or comparisons.
How to verify / match
- Enter the text you want to check in “Text to match”.
- Paste the expected SHA-256 digest in “Hash to match”.
- Click Verify to confirm the digest matches.
Common use cases
- Integrity checks for strings/files
- API payload hashing
- Security identifiers and fingerprints
- Debugging and validation in apps

Is SHA-256 reversible?
No. Hashing is one-way. You can only verify by hashing the same input and comparing outputs.
What output encoding should I choose?
Hex (lower) is the most standard for SHA-256.
