What MD5 Actually Does MD5 (Message Digest Algorithm 5) produces a 128-bit hash value (32 hexadecimal characters). It's one-way - you cannot reverse it to get the original input.

Try every possible combination until a match is found.

// Example of MD5 hashing $string = "Hello World"; $hash = md5($string); echo $hash; // Outputs: b10a8db164e0754105b7a99be72e3fe5 Since MD5 is a hash function, there's no decryption function like md5_decrypt() .
