The cryptographic difference between private keys and public keys

Having a clear understanding of the differences between cryptography's private and public keys

Public key cryptosystems are: (more than one may be true, choose all that are true) a offering a simpler way for key distribution B faster than symmetric C the preferred solution when the message we want to encrypt is very large D easily used to offer integrity E requiring advanced hardware in order to use them F easily used to offer confidentiality G marketed better than symmetric that is why people prefer them H using one key for encryption and a different key for decryption

true or false 11. One property of encryption algorithm is that someone can know the details of the algorithm and still not be able to decipher the encrypted message without knowing the key that the algorithm used to encrypt the message.
