MD5 hash calculator
A legacy algorithm producing a 128-bit digest. Collisions can be produced in practice, so it is unsafe for passwords and signatures; use it only for corruption checks and legacy compatibility.
MD5 is broken against collision attacks. Do not use it for password storage, signatures or certificates; it is only for legacy compatibility and corruption checks.
