Private and Public Key have a one-way relationship. A Private key is a very large random number that is generated by a computer. A Public Key is unique and is derived from a Private Key. The most important thing is that A Private Key cannot be solved back using the Public Key. Hence, a one-way relationship

The 2 use-cases are Encryption (sending a secret message to a specific person in a public community or forum) and Digital Signatures (a unique fingerprint that serves as verification of identity and functions as an integrity part of the transaction)

Transactions utilize digital signatures to function. You can also use it for encryption.

- Describe the concept of public and private key with your own words.
Public Key - accessible to everyone in the network if the data is not encrypted
Private Key - if the data is encrypted only the private key allows the user to access the data - What 2 use-cases can public key cryptography be used for?
Mainly to create digital signatures and encrypt data.

A public key is akin to an email address that can be shared with all on the internet so as to be able to receive messages (whether they be encrypted or not). A private key is akin to the corresponding âpasswordâ that is used to access the messages sent to the corresponding email address. Moreover, this public key is needed in order for the email address to be able to actually send emails to any other addresses.
-
Public key cryptography can be used for both encryption and digital signatures. When it comes to encryption, the private key is used to decrypt messages sent to the corresponding public key. On the other hand, when it comes to digital signatures, the private key is used to sign messages/transactions.

A public key is the front end part of an encrypted system which is visible and accessible to others besides you and the private key is the back end part of this system which is wholly and completely unique to you which can be used as a digital signature or means of decrypting information that was encrypted and sent with the public key. Your private key, as the name implies should not be shared with anyone or left in a vulnerable, accessible place.
Public key cryptohgraphy can be used to encrypt sensitive information during the process of sharing if you have the private key associated with the public one, or for digital signatures to verify the sender or owner of the asset being transferred or agreement be made in the case of smart contracts.

A private key is a random alpha numeric value which is typically very long and must be kept secret. A public key is derived from the private key and can be shared with anyone sending you a message.
It can be used for sending encrypted messages or for signing transactions placed on the blockchain.

The private key is used to decrypt data and must never be shared. Public key is used to convert the message to an unreadable form and can be shared with others.

- A private key is a randomly generated large number from which a public key can be derived.The private key has to be hidden from others while the public key is for all to see.You can only go from private to public and not the other way.
- These are encryption and digital signatures.

a) A private key is generated by the ownerâs computer, or by a computer requested by someone (a vendor ~centralized exchange), and is a long random number. Through math, the private key is then used to create a public key. - What 2 use-cases can public key cryptography be used for?
a) Encryption - The public key is distributed, other people can then use the public key to encrypt messages that can only be decrypted by the private key. This allows anyone to send the private keyâs owner an unreadable message (secret message) and only the holder of the private key can decrypt and read the message.
b) Digital Signature â Used to verify a sender. The private key holder can create a signature (math based number derived from the private key). The signature is linked, through math, uniquely to the private key. Others receive signed messages that can be verified using the message data, signature, and the public key generated from the private key (key pair) to verify the contents of the message came from the private key holder and that they have not been tampered (altered).

A private key is a random number generated by a computer and is used to decrypt messages. A public key is derived from the private key, can be communicated to anyone and is used to encrypt messages.
2. What 2 use-cases can public key cryptography be used for?
The 2 use cases for public cryptography are encryption and digital signature.
- Encryption: a sender will use the receiverâs public key to encrypt a message. The receiver will then use his private key to decrypt it.
- Digital Signature: messages are digitally signed using the private key in order to identify the sender.

Private and public keys are âkey elementsâ(pun intended :-)) in our digital world. They are used in almost every digital field where encryption and/or verification need. - What 2 use-cases can public key cryptography be used for?
Encryption, for secret message sending on an open network; and digital signatures where I am able to validate if the true sender sent a particular message.

your private key is for yourself and nobody knows what it is, and by your public key you are able to send and receive messages. And the private key validates the public key and vica versa.
2 send and receiving encrypted messages is one. validation is second.

1. Describe the concept of public and private key with your own words.
A private key is a large randomly generated number which, via some mathematical operation (hashing?), is used to generate another mathematical number which is used as the public key. This process is done in such a way that the private key can never be computed using the public key. Also, due to the private key being a very very large number, it is near impossible for two users on a network to have been assigned the same private key.
2. What 2 use-cases can public key cryptography be used for?
Private & public keys are used to encrypt messages and in the case of bitcoin theyâre used to digitally sign transactions. For e.g. when somebody wants to become a participant on the bitcoin network, they open up a wallet and after doing so theyâre assigned a private key which is used (via math) to generate a public key which is again used (via math) to generate a public bitcoin wallet address.
When another person, the sender, wants to send this new person some bitcoin, letâs call this person the receiver, then the sender will digitally sign the transaction data (how much he/she is sending) using their own private key.
Upon receipt of the transaction data (number of bitcoin being received including digital signature) this recipient can then use the senderâs public key to verify the digital signature, since both the senderâs public key and digital signatures were generated using some math operations on the senderâs private key.

In bitcoin, private keys are generated by the ownerâs computer when creating a wallet. Itâs for the ownerâs eyes only from this key a public key is created via a mathematical function. The public key is used to create a bitcoin address and can be given to others. The private key must be kept safe and is used to sign transactions, allowing others to know who sent the bitcoin.

- Describe the concept of public and private key with your own words.
The main concept of Public and private keys is for integrity and security. A private key produces a public key. When information is encrypted and used with the public key the only way to decrypt the information is with the private key. This concept keep the integrity of the information and also the key to who can view this information. - What 2 use-cases can public key cryptography be used for?
One use for public key cryptography is in the case of encryption to send digital information privately and securely digitally. And in another case this innovation can be used for integrity of identifying digital signatures though private and public keys.
