Hashing algorithms (SHA, MD5) in Cybersecurity - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to create an MD5 hash of a string in Python.

Cybersecurity

import hashlib

hash_object = hashlib.md5()
hash_object.update([1].encode())
print(hash_object.hexdigest())

💡 Hint

Common Mistakes

Using the module name instead of the string to hash.

Passing the encode method instead of calling it on the string.

The string password123 is encoded and passed to the MD5 hash function to generate the hash.

Complete the code to create a SHA-256 hash of a string in Python.

Cybersecurity

import hashlib

hash_object = hashlib.[1]()
hash_object.update('hello world'.encode())
print(hash_object.hexdigest())

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using MD5 instead of SHA-256.

Using uppercase letters in the function name.

The sha256 function from hashlib creates a SHA-256 hash object.

Fix the error in the code to correctly generate an MD5 hash.

Cybersecurity

import hashlib

hash_object = hashlib.md5('data'.[1]())
print(hash_object.hexdigest())

💡 Hint

Common Mistakes

Using decode instead of encode.

Calling hexdigest or update on the string.

The string must be encoded before passing to the MD5 function. Calling encode() converts the string to bytes.

4fill in blank

hard

Fill both blanks to create a SHA-1 hash of a string and print the hexadecimal digest.

Cybersecurity

import hashlib

hash_object = hashlib.[1]()
hash_object.[2]('example'.encode())
print(hash_object.hexdigest())

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using md5 instead of sha1.

Using digest instead of update to add data.

The sha1 function creates the hash object, and update feeds the encoded string to it.

5fill in blank

hard

Fill all three blanks to create a SHA-512 hash of a string and print the hexadecimal digest.

Cybersecurity

import hashlib

hash_object = hashlib.[1]()
hash_object.[2]('secure'.encode())
print(hash_object.[3]())

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using digest instead of hexdigest for output.

Forgetting to encode the string before updating.

sha512 creates the hash object, update adds the encoded string, and hexdigest returns the hash as a readable hex string.
