frequently asked questions
what is MD5 used for?
MD5 is still common for quick file integrity checks and legacy systems, but it is not secure for passwords or signatures.
why is MD5 not secure?
collisions can be created on purpose, so two different files can share one MD5. use SHA-256 for security.
is my input sent anywhere?
no. MD5 is computed by code running on this page.
