Hash & checksum
SHA-256, SHA-384, and SHA-512 for text or files.
About Hash & checksum
Produce a digest of text or file bytes. Comparing the calculated digest with a trusted expected value can show whether the bytes match.
Steps, example, and limitations
How to use it
- Choose a supported SHA algorithm and a text or file input.
- Calculate the digest.
- Copy it or compare it with the expected checksum.
Example
Input
SHA-256 of UTF-8 text: abc
Result
ba7816bf8f01cfea414140de5dae2223b00361a396177a9cb410ff61f20015ad
Things to know
- A hash is not encryption and cannot be used to recover the original input.
- A matching checksum only helps when the expected value comes from a trustworthy source. Use HMAC when a shared secret is part of the verification.
