Exam 712-50 topic 1 question 246 discussion

Encryption Basics: To ensure that an important and confidential email can only be read by the recipient, you should use the recipient's public key to encrypt the message. The recipient will then use their private key to decrypt it.

I got my CEH only months ago, and there are 2 ways to use PKI: 1.-CONFIDENITAL:When encrypting, you use recipient‘s public key to write a message and recipient use their private key to read it .......THEREFORE C IS OK 2.-NON-REPUDIATON-When signing, you use your private key to write message‘s signature, and recipient‘s use your public key to check if it‘s really yours

Using Recipients public key will ensure that only the recipient can decrypt using his/her private key. If sender's private key is used, anyone will be able to decrypt using the senders public key & will only help in "non-repudiation"...of course practically it is a combination of recipients public key and senders private key

Should the answer be sender's private key?
