Program : HMAC

In this program, you are required to invoke the scrypt algorithms that are implemented in hashlib build-in library. Your program does the following:

  • Read the plaintext password as a text string
  • Encode the password into byte array, with utf-8 encoding
  • Read the salt byte array as a hex string
  • Invoke the scrypt method with parameters n = 4 n=4 n=4, r = 8 r=8 r=8, p = 16 p=16 p=16
  • Output the result byte array as a hex string

Example Input

Thi$ i$ my passw0rd!
477d15cb740ca1da08f6d851361b3c80

Example Output

fd5963b9e6905d36ca8d00e3a740a3ab7a40b3d60237b6f2ed3025eee770f2d71bc95ba3e98265bea4308250d02f0e10bb78e710d9f0ef7ae9a4fa52a0818d27

solution code

import hashlib
import base64

# define the function decode_utf8
def decode_utf8(in_bytes: bytes) -> str:
    return in_bytes.decode('utf-8')
#

 Read the plaintext password as a text string
password_str: str = input("input the plaintext password:")
# Encode the password into byte array, with utf-8 encoding
password_bytes: bytes = password_str.encode("utf-8")
# Read the salt byte array as a hex string
salt_str: str = input("input the salt:")
salt_bytes: bytes = bytes.fromhex(salt_str)
# Invoke the scrypt method with parameters n = 4 ,r = 8 ,p = 16
n: int = 4
r: int = 8
p: int = 16
result_bytes: bytes = hashlib.scrypt(password_bytes, salt=salt_bytes, n=n, r=r, p=p)
# Output the result byte array as a hex string
result_str: str = result_bytes.hex()
print(result_str)

output

input the plaintext password:Thi$ i$ my passw0rd!
input the salt:477d15cb740ca1da08f6d851361b3c80
fd5963b9e6905d36ca8d00e3a740a3ab7a40b3d60237b6f2ed3025eee770f2d71bc95ba3e98265bea4308250d02f0e10bb78e710d9f0ef7ae9a4fa52a0818d27
