Frequently asked questions
What is SHA-256 used for?
Use it for file and string checksums, content addresses, and integrity checks. It is not a password hash — use bcrypt for passwords.
How do I use the free online SHA-256 tool?
Fill in Input. This field is required. Click Run and copy the result under the form.
What can I paste or upload into SHA-256?
Paste the text as UTF-8. The digest of abc is ba7816bf8f01cfea414140de5dae2223b00361a396177a9cb410ff61f20015ad.
What output does SHA-256 give me?
64 hex characters. Changing one character in the input changes the digest completely.
Is SHA-256 free, and is my input private?
Yes — Your input is processed in memory for this request only. It is not saved to disk or the database, and it is cleared after the tool finishes.
Why does an online checksum of my file not match?
This tool hashes the characters you paste, not a file on disk. A trailing newline, or UTF-8 versus UTF-16, changes the digest. Hash the exact bytes.
Inputs are processed in memory only and are not saved to disk or the database. Data exists only for the duration of your request.
