How to Encrypt and Decrypt Password in Python

Encrypting and Decrypting Passwords in Python

Encrypting and decrypting passwords in Python is crucial for ensuring the security of sensitive information. One common method to achieve this is by using cryptographic hashing functions. Here's how you can encrypt and decrypt passwords in Python:

1. Encrypting a Password: Use a secure hashing algorithm such as SHA-256 or bcrypt to convert the password into a fixed-length hash. This ensures that the original password cannot be easily retrieved from the stored hash.
2. Decrypting a Password: Since passwords should not be decrypted (as it defeats the purpose of encryption), the focus should be on comparing encrypted versions of the password.

Here's a simple example using the hashlib library in Python to encrypt a password:

import hashlib
password = 'mysecretpassword'
hashed_password = hashlib.sha256(password.encode()).hexdigest()
print(hashed_password)

Remember, always store and compare hashed passwords instead of decrypting them. This helps maintain the security of your system and protects user data from unauthorized access.
