- The concept of a public and a private key pair is that it creates a digital footprint and you can encrypt messages and information you want to send on a public networkk. The digital footprint can be created on for example a transaction when your private key signs the transaction and the blockchain system for example knows that you sent the transaction through mathematics because your public key is linked to your private key.
- The 2 usecases of public key cryptography is encrypting messages meant for a specific person, and create digital footprints (identification).

1. Describe the concept of public and private key with your own words.
a. A private key is a series of numbers that is only known to the owner. This private key is tied to the person and is used to either sign or encrypt information. A public key is derived form the private key and is publicly available. It can be used to encrypt messages or verify a signature. The process to derive the public key from the private only works one way. So while you can use a public key to verify that it was derived from a certain private key, you can never reconstruct the private key. To go from the private to the public key is, however, always possible.
2. What 2 use-cases can public key cryptography be used for?

Imagine you want to send someone a message which only the reciever can read, you get the Public Key from the Reciever and encrypt your message.
The only way to be able to read the message after it has been encrypted is to get the private Key from the reciever.
If the reciever somehow looses his private Key. He will not be able de decript the info. If somehow someone else gets your private key, all your crypto will esentially be his now.
Use cases:
1) Encryption
2) Digital Signatures -(verify Identity and indtegrity)

Public and private keys are about identification, a verification that you sent the message. A private key is used as digital signatures for transactions, when you own cryptocurrency you really own a private key to the asset. A public key is used for encrypt messages.
On a open forum on the internet, a public key can be used to encrypt a sensitive message so if the reicever logs in with his private key he can access that message decrypted.
