What Is an MD5 Hash?
MD5 is a cryptographic hash function that converts any input text into a fixed 32-character hexadecimal string. The same input always produces the same hash, and even a tiny change to the input produces a completely different result, which makes hashes useful for checking whether two pieces of data are identical.
MD5 is fast and simple, which is why it remains common for non-security uses like checksums and cache keys — but it is considered cryptographically broken for security purposes such as password storage, where SHA-256 or a dedicated password-hashing algorithm should be used instead.
