Does my file get uploaded anywhere?

No, hashing happens locally using the browser's Web Crypto API; files never leave your device.

Which algorithms are supported?

SHA-1, SHA-256, SHA-384, and SHA-512.

Is the comparison case-sensitive?

No, checksums are compared case-insensitively and with surrounding whitespace trimmed.

Does it work offline and on mobile?

Yes. Once the page has loaded it keeps working without a network connection, and the layout is responsive so it stays usable on phones and tablets.

Do I need an account or an API key?

No. Every tool on Coders Hub is free to use with no sign-up, no API key and no usage limits.

About the Checksum Comparator

Compute a SHA-1, SHA-256, SHA-384 or SHA-512 checksum of pasted text or an uploaded file using the Web Crypto API, and compare it against an expected checksum to verify file integrity.
