What this tool does
Generate a 64-character hexadecimal SHA-256 hash for UTF-8 text, choose uppercase or lowercase, and copy the result.
- The output is 64 hexadecimal characters, optionally lowercase or uppercase.
- SHA-256 is a one-way digest, not encryption, and the original text cannot be restored from the digest.
- The tool does not save input; sensitive content should still be processed only on trusted devices.
How to use it
- Enter the text you want to hash.
- Choose Lowercase or Uppercase.
- Click "Generate SHA-256".
- Check and copy the resulting hash.
Common uses
- Verify that different systems produce the same digest for the same text.
- Generate integrity flags for test data or configuration content.
- Compare hashes of UTF-8 text before and after modification.

FAQ
Can SHA-256 be decrypted?
No. SHA-256 is a one-way hash function and cannot reliably restore the original input from the digest.
Will we get stable results for Chinese and emoji?
Yes. The tools are uniformly encoded in UTF-8, so the same sequence of characters will produce the same digest.
Will the input content be uploaded?
Your input stays in your browser and is not uploaded.
Is there a difference between uppercase and lowercase results?
Only the display format is different, the hash bytes represented are exactly the same.
