You can then use the new and update methods: In this case, "DSA" is available on my computer. Using algorithms_available, we can find the name of the algorithm you want to use. Now suppose you need an algorithm provided by OpenSSL. Hash_object = hashlib.sha512(b'Hello World') Hash_object = hashlib.sha384(b'Hello World') Hash_object = hashlib.sha256(b'Hello World') Hash_object = hashlib.sha224(b'Hello World') Hash_object = hashlib.sha1(b'Hello World') Hash_object = hashlib.md5(mystring.encode()) Mystring = input('Enter String to hash: ') So, if you need to take some input from the console, and hash this input, do not forget to encode the string in a sequence of bytes: In previous versions of the library, it used to take a string literal. It is important to note the "b" preceding the string literal, this converts the string to bytes, because the hashing function only takes a sequence of bytes as a parameter. hexdigest returns a HEX string representing the hash, in case you need the sequence of bytes you should use digest instead. SHA 256 HASH CALCULATOR PYTHON CODEThe code above takes the "Hello World" string and prints the HEX digest of that string. Hash_object = hashlib.md5(b'Hello World') algorithms_guaranteed only lists the algorithms present in the module. In this case you may see duplicate names in the list. The algorithms_available method lists all the algorithms available in the system, including the ones available trough OpenSSl. Now we use algorithms_available or algorithms_guaranteed to list the algorithms available. If you want to run this examples in Python 2.x, just remove the algorithms_available and algorithms_guaranteed calls. This code is made to work in Python 3.2 and above. hashlib implements some of the algorithms, however if you have OpenSSL installed, hashlib is able to use this algorithms as well. The hashlib module, included in The Python Standard library is a module containing an interface to the most popular hashing algorithms. The message length ranges from 160 bits to 512 bits. These algorithms are used widely in several cryptographic applications.
