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 cannot be reversed.

When should I use encryption instead of hashing?

Use encryption when you need to protect data confidentiality and allow for data recovery. Hashing is best for verifying data integrity, like storing passwords.

Can you give me examples of when to use each?

Sure! Use encryption for sensitive data like credit card information. Use hashing for password storage to ensure they can't be easily retrieved.

Are there any security risks associated with either?

Yes, encryption can be vulnerable if keys are not managed properly. Hashing can be susceptible to collisions or brute-force attacks if not implemented with strong algorithms.
