The Message-Digest Algorithm 5 (MD5) was originally designed by Ronald Rivest in 1991 to replace its less secure predecessor, MD4. It acts as a digital fingerprinting mechanism, transforming any input up to 2642 to the 64th power bits in size into a fixed-length 128-bit digest.

output. Regardless of whether the input is a single letter or an entire movie file, the resulting MD5 hash will always be 32 characters long in hexadecimal format. How It Works
