Frequently asked questions
What is MD5?
MD5 is a widely used algorithm that turns any input into a fixed 128-bit (32 hex character) fingerprint. Given the same input, it always produces the same hash.
Is MD5 secure for passwords?
No. MD5 is considered cryptographically broken and shouldn't be used to store passwords or for anything security-sensitive — use it for checksums and quick comparisons only, not for protecting secrets.
Is my data uploaded anywhere?
No. Hashing happens locally in your browser using JavaScript — nothing you type or upload is sent to a server.
Can I hash a whole file, not just text?
Yes — use the "MD5 a file" section further down the page to hash any file directly in your browser.
