Nice video, however... At 4.18 you state that 'Alice may encrypt with her private key..'. And that bob may decrypt with Alice's public key..

Though this is possible, it is not the norm.

Encryption would normally be done using the public key.

It is the private key that should be used to decrypt messages... since it is secret.

You would not want the key to your data to be public !
