What is the function of a public key in encryption?

• It stores sensitive information securely.

• It generates random passwords.

• It encrypts messages to be sent securely.

• It decrypts the received messages.

• They ensure data is unreadable to unauthorized users.

• They provide faster data transfer.

What is the purpose of hashing passwords on web servers?

• To verify the user's identity without encryption

• To link them with user emails

• To encrypt them in a way that is hard to reverse

• To make them easier to remember

What does the process of hashing ensure about passwords?

• They can be shared securely over the internet.

• They are difficult to reverse back to original form.

• They are easy to decrypt when needed.

• They are linked to specific IP addresses.
