The value you get from a MD5 function is the fingerprint of a block of data (any type of file, even programs can be considered data), it allows you to confirm that your copy of the data is the same as the original (no corruption), because slight changes to the input of the MD5 algorithm will produce a different string.
MD5 check sum is unique for a file content and is used to check the integrity of the file content. If file is to be transferred using network, recipient can calculate the MD5 hash and check it with the MD5 check sum of sender, if both are same, he can be sure of non-corruption of file in transit.
MD5
unsigned char [16]
In cryptography, MD5 (Message-Digest algorithm 5) is a widely used, partially insecure cryptographic hash function with a 128-bit hash value. As an Internet standard (RFC 1321), MD5 has been employed in a wide variety of security applications, and is also commonly used to check the integrity of files. An MD5 hash is typically expressed 32-character string of hexadecimal numbers.The MD5 hash also known as checksum for a file is a 128-bit value, something like a fingerprint of the file. There is a very small possibility of getting two identical hashes of two different files. This feature can be useful both for comparing the files and their integrity control. Let us imagine a situation that will help to understand how the MD5 hash works. Alice and Bob have two similar huge files. How do we know that they are different without sending them to each other? We simply have to calculate the MD5 hashes of these files and compare them.The MD5 hash is used in many websites.

the md5 in this site is fake md5
MD5 is one of the ways of encrypting passwords and making them secure than leaving them plain. MD5 is of bit 32.

Unfortunately, md5 encryption can NEVER decrypted, that is the whole point of it!

md5() is one-way encryption method. Example: $test_string="php"; $md_encoded_string=md5($test_string); But, you can't decode the string back to php.So, if you need to check the entered string is php or not $user_entered_string=md5($_POST['user_input']); if($md_encoded_string == $user_entered_string) { echo "input matched"; }
