Safe Computing

PII in CompSci Projects: PII includes personal data like names, addresses, SSNs. Safeguarding involves encryption, access control, and compliance with privacy laws for sensitive information storage.
Good and Bad Passwords: Good passwords are lengthy, diverse, and avoid common words. Bad passwords are short, predictable, and lack complexity. Two-factor authentication adds an extra layer of security.
Symmetric & Asymmetric Encryption: Symmetric uses one key for encryption and decryption, while asymmetric employs a key pair: public for encryption, private for decryption, enhancing security.
AWS Encryption: AWS Key Management Service (KMS) secures data in S3 by managing encryption keys, adding protection to stored information within an AWS deployment.

Python Password Checker:

def check_password_strength(password): # Checks password strength criteria.
 # Define criteria for a strong password
 min_length = 8
 has_upper = any(char.isupper() for char in password)
 has_lower = any(char.islower() for char in password)
 has_digit = any(char.isdigit() for char in password)
 has_special = any(char in "!@#$%^&*()-_=+[]{};:'\"<>,.?/\\|`~" for char in password)
 # Check if password meets the criteria
 if len(password) >= min_length and has_upper and has_lower and has_digit and has_special:
     return "Strong password!"
 else:
     return "Weak password! Password should be 8+ characters with uppercase, lowercase, digit, and special characters."
# Get user input for password
user_password = input("Enter a password: ")
# Check the strength of the password
result = check_password_strength(user_password)
print(result)
