python hash object code example

Example 1: python hash string

import hashlib
hash_object = hashlib.sha256(b'Hello World')
hex_dig = hash_object.hexdigest()
print(hex_dig)

Example 2: python hash function

# Hash Function 
# SHA hash algorithms. 

import hashlib 

# initializing string 
str = "TYCS"

# encoding TYCS using encode() 
# then sending to SHA1() 
result = hashlib.sha1(str.encode()) 

# printing the equivalent hexadecimal value. 
print("The hexadecimal equivalent of SHA1 is : ") 
print(result.hexdigest()) 

# encoding TYCS using encode() 
# then sending to SHA224() 
result = hashlib.sha224(str.encode()) 

# printing the equivalent hexadecimal value. 
print("The hexadecimal equivalent of SHA224 is : ") 
print(result.hexdigest())

# encoding TYCS using encode() 
# then sending to SHA256() 
result = hashlib.sha256(str.encode()) 

# printing the equivalent hexadecimal value. 
print("The hexadecimal equivalent of SHA256 is : ") 
print(result.hexdigest()) 

# initializing string 
str = "TYCS"

# encoding TYCS using encode() 
# then sending to SHA384() 
result = hashlib.sha384(str.encode()) 

# printing the equivalent hexadecimal value. 
print("The hexadecimal equivalent of SHA384 is : ") 
print(result.hexdigest()) 

# initializing string 
str = "TYCS" 

# initializing string 
str = "TYCS"

# encoding TYCS using encode() 
# then sending to SHA512() 
result = hashlib.sha512(str.encode()) 

# printing the equivalent hexadecimal value. 
print("The hexadecimal equivalent of SHA512 is : ") 
print(result.hexdigest())

Example 3: python hash string

import uuid
import hashlib
 
def hash_password(password):
    # uuid is used to generate a random number
    salt = uuid.uuid4().hex
    return hashlib.sha256(salt.encode() + password.encode()).hexdigest() + ':' + salt
    
def check_password(hashed_password, user_password):
    password, salt = hashed_password.split(':')
    return password == hashlib.sha256(salt.encode() + user_password.encode()).hexdigest()
 
new_pass = input('Please enter a password: ')
hashed_password = hash_password(new_pass)
print('The string to store in the db is: ' + hashed_password)
old_pass = input('Now please enter the password again to check: ')
if check_password(hashed_password, old_pass):
    print('You entered the right password')
else:
    print('I am sorry but the password does not match')

Example 4: python hash

from hashlib import blake2b
import time
k = str(time.time()).encode('utf-8')
h = blake2b(key=k, digest_size=16)
h.hexdigest()

Example 5: hash in python

hash(object)
