Frequently asked questions
What is SHA-224 used for?
Use it when a protocol asks for SHA-224 specifically. For general checksums, SHA-256 is the more common choice.
How do I use the free online SHA-224 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-224?
Paste the message as UTF-8. A trailing newline is part of the input and changes the digest.
What output does SHA-224 give me?
56 lowercase hex characters. It is not a prefix of the SHA-256 digest of the same input.
Is SHA-224 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.
Can I take the first 56 hex characters of SHA-256 instead?
No. SHA-224 uses different initial values. Copy the digest from this page if the spec says SHA-224.
Inputs are processed in memory only and are not saved to disk or the database. Data exists only for the duration of your request.
