Learn about asymmetric ciphers.
- [Instructor] Unlike symmetric algorithms,…asymmetric algorithms don't need a shared secret key.…For this reason,…they're often referred to as public key cryptography.…With asymmetric algorithms,…a private key is used to encrypt the data…and a public key is used to decrypt the data.…Asymmetric key cryptography provides us with…confidentiality, integrity, authentication,…and non-repudiation for our messages being sent.…To provide confidentiality of the data…the data should only be encrypted…using the receiver's public key.…
By doing so, the receiver's private key…can decrypt the contents,…ensuring that it is safe from prying eyes.…In fact, once you encrypt the data…using the receiver's public key,…even you, the sender, can't decrypt that data.…To provide authentication though,…the message should be encrypted…using the sender's private key.…By doing so, anyone with access…to the sender's public key,…which could be anyone in the world,…can open a message and read it.…This doesn't provide us with any confidentiality.…
