What is the difference between encryption and hashing?

Encryption is a process that transforms data into a secure format, making it unreadable without a key. Hashing, on the other hand, converts data into a fixed-size string of characters, which is typically a digest that represents the original data.

Can you give me examples of when to use each?

Sure! Use encryption when you need to protect sensitive data, like credit card information, during transmission. Use hashing for data integrity checks, like verifying passwords.

Are both methods secure?

Yes, both methods are secure but serve different purposes. Encryption protects data confidentiality, while hashing ensures data integrity.

What happens if a hash is compromised?

If a hash is compromised, it can lead to vulnerabilities, especially if it's used for password storage. It's crucial to use strong hashing algorithms and salting techniques.
