hash string python code example
Example 1: python create hash from string
import hashlib
hash_object = hashlib.sha256(b'Hello World')
hex_dig = hash_object.hexdigest()
print(hex_dig)
Example 2: how to convert hash to string in python
print(hashlib.algorithms_available)
print(hashlib.algorithms_guaranteed)
Example 3: 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 4: 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')
