Which algorithms are computed?

SHA-1, SHA-256, SHA-384 and SHA-512 are produced together for the same input, so you can compare digests without re-running the tool.

Not currently — the tool hashes text you paste. For file checksums use your operating system: shasum, certutil or Get-FileHash.

Not for signatures or anything an attacker benefits from forging — it is broken by collision attacks. Prefer SHA-256 or stronger; SHA-1 is here for legacy checks.

Is the input uploaded?

Frequently asked

Which algorithms are computed?: SHA-1, SHA-256, SHA-384 and SHA-512 are produced together for the same input, so you can compare digests without re-running the tool.
Can I hash a file?: Not currently — the tool hashes text you paste. For file checksums use your operating system: shasum, certutil or Get-FileHash.
Is SHA-1 still safe?: Not for signatures or anything an attacker benefits from forging — it is broken by collision attacks. Prefer SHA-256 or stronger; SHA-1 is here for legacy checks.
Is the input uploaded?: No. Hashing happens in the page.
