We have also looked at two use cases – one where you can directly pass binary string for encryption and the other where you convert a plain string to binary sequence and then pass it for hashing. In this article, we have learnt how to encrypt string using md5 algorithm. To interoperate with such implementations, format the return value of the ComputeHash methods as a hexadecimal value. Note that some MD5 implementations produce a 32-character, hexadecimal-formatted hash. The ComputeHash methods of the MD5 class return the hash as an array of 16 bytes. Hash_value = hashlib.md5(bytes).hexdigest() The hash size for the MD5 algorithm is 128 bits. For example, here is an example where we find md5 has of a file data.txt, by looping through its contents and passing them to md5 hash function. Generally, this step is used as a part of a larger function or application. Finally, we have displayed the encoded string as hex format. In the above example, we have converted a string into binary sequence and passed it to md5 hash function. Hashing a string with MD5 multiple times will always produce the same 128-bit value. ' \x84\x95\x00\xe4X]\xabA\x96\xec\x9aA^\xdf\x8f' MD5 is a commonly used hashing function which outputs a 128-bit hash value. Here is an example where we use a plain text string and convert it to binary sequence using encode() function before passing it to md5 function. ![]() In such cases, you need to convert it into binary sequence before you pass it to md5 hash function. Many times you may not have a binary string as input. We use digest function to display the encoded result. So we can directly pass this to hashlib.md5 function for encryption. In the above example, we have defined a string variable ‘sample’ with binary encoding. hexdigest () : Returns encoded data in hexadecimal format. digest () : Returns 128-bit encoded data in byte format. encode () : Converts a string into bytes to be acceptable by hash function. ' \x84\x95\x00\xe4X]\xabA\x96\xec\x9aA^\xdf\x8f MD5 hash function accepts a sequence of bytes and returns a 128-bit hash value. Now we will look at a few examples of MD5 hash calculation. ![]()
