Print('MD5:', hashlib.md5(message).hexdigest()) We gonna use different hash algorithms on this message string, starting with MD5: # hash with MD5 (not recommended) # encode it to bytes using UTF-8 encoding In this tutorial, we will be using hashlib built-in module to use different hash algorithms in Python, let's get started: import hashlib Read also: How to Transfer Files in the Network using Sockets in Python. In fact, whether you're storing your files on a cloud storage system, using Git version control system, connecting to an HTTPS website, connecting to a remote machine using SSH, or even sending a message on your mobile phone, there's hash function somewhere under the hood. That's not it, there are many examples of their use, some examples include: digital signatures, public-key encryption, message authentication, password protection and many other cryptographic protocols. Using hashing values, you'll be able to tell if some file isn't modified since creation ( data integrity).

Now, you may be thinking, then what's the benefit of using hashing algorithms ? Why just use encryption ? Well, even though encryption is important for protecting data ( data confidentiality), sometimes it is important to be able to prove that no one has modified the data you're sending. The most important thing about these hash values is that it is impossible to retrieve the original input data just from hash values.

The output hash value is literally a summary of the original value.

It is fully compatible with UTF-8 encoding. The SHA1() function returns a string with the SHA1 encrypted hash as a string with 40 characters. The SHA ( Secure Hash Algorithm) can be used to encrypt data for secure transfer between applications.
