FAQ

자주 묻는 질문

Q1. Is my input text sent to a server?

No. All calculations happen entirely in your browser and are never sent to or stored on a server.

Q2. Which hash algorithms are supported?

CRC32, MD5, SHA-1, SHA-256, SHA-384, SHA-512, SHA3-256, and SHA3-512 are all calculated at once, since different use cases call for different algorithms.

Q3. I heard MD5 and SHA-1 aren't secure anymore.

That's right. MD5 and SHA-1 have known collision attacks, so they're not recommended for security purposes like password storage. They're still widely used for non-security purposes like file integrity checks, though.

Q4. Does a different whitespace or line break change the result?

Yes. A hash changes completely if even a single input byte changes. Leading/trailing whitespace and line breaks need to match exactly to get the same hash.

Q5. I want to verify a downloaded file's checksum.

This page is text-only. To check whether a downloaded file is intact, use the File Checksum Verifier tool instead.
