Applications of cryptography- Project Task -- 2

Note:For this assignment, feel free to use aprogramming language of your choice. Python is recommended. For Python, the packages PyCryptodome ([login to view URL]) or PyCryptodomex ([login to view URL]) are recommended. Submission requirements: Your submission must contain:The source code, the executable(s) if any, and all other related files.The project report, which will contain the instructions for running your program, and thescreenshots demonstrating that your program works according to the assignment tasks. Tasks:[login to view URL] atext file“[login to view URL]” with the following text “This is the test message 1”.Create a copy of this file with name “[login to view URL]”. Generate a random 128-bit key “k”.Encrypt the contents of “[login to view URL]” using the AES-ECB mode and the key “k”, and save theresulting ciphertext to a file “[login to view URL]”. Before saving, encode the ciphertext using Base64 (so that it can be conveniently printed on the screen).Encrypt the contents of “[login to view URL]” in the same way as described above, on the same key “k”, and save the contents to a file “[login to view URL]”.Print the contents of the files “[login to view URL]” and “[login to view URL]” to the screen (to make sure that theresulting ciphertexts are the same). [login to view URL] Task 1 but use the AES-CBC mode with randomized IV. Use the same key “k”.Print the contents of the files “[login to view URL]” and “[login to view URL]” to the screen (to make sure that theresulting ciphertexts are different). [login to view URL] a random 256-bit key “k1”. Compute an HMAC authentication tag for “[login to view URL]” using “k1”, and save it to afile “[login to view URL]”, using Base64 [login to view URL] the contents of “[login to view URL]” to “This is the test message 2”.Compute an HMAC authentication tag for the updated “[login to view URL]” using “k1”, and save it to afile “[login to view URL]”, using Base64 encoding. Print the contents of the files “[login to view URL]” and “[login to view URL]” to the screen (to make sure that theresulting authentication tags are different). [login to view URL] a random 256-bit key “k2”. Encrypt the contents of “[login to view URL]” using the AES-GCM-256 mode and the key “k2”, and save theresulting ciphertext to a file “[login to view URL]”, using Base64 [login to view URL] the contents of “[login to view URL]”, and print the result to the screen to make sure that thedecryption has been performed [login to view URL] the first symbol in the file “[login to view URL]” to a different alphanumerical character (to be consistent with Base64 encoding).Attempt to decrypt the updated ciphertext “[login to view URL]” and display the result (to make sure that the ciphertext is rejected).
