Public key- It is derived from a private key and can be used by others to send encrypted information to you. It is safe to share with others.
Private key- This is randomly generated and can be used as a digital signature as well as to de-crypt information sent from others that was encrypted with your public key. -
Public key is used to encrypt information that others are sending to you. They also are used to create a public bitcoin address for receiving bitcoin

- Describe the concept of public and private key with your own words
- Public and private keys are generated from a random number being put through a hashing function. The public key is used to encrypt data and the private key is used to decrypt the encrypted data.
- What 2 use-cases can public key cryptography be used for?
- Encryption and Digital Signatures for verifying identity and integrity.
The private key is the most private key which is generated random number. From this, the public key is generated, which is public and accessible to the rest of the world. The public key is used to encrypt messages, which can only be decrypted by the private key…
The two use cases are encryptions and digital signatures.

Concept is to create more security by having a Public Key that is derived(hashed) out from the Private key.
2 use-cases is to send/strem info that is sensitive like medical data/telemedicine & sending currency.

The 2 use cases of public key cryptography are: 1 Encryption, 2 Digital signatures. Digital signatures verify who sent the message since the private key derives the public key which creates the bitcoin address. You send bitcoin using your private key and receive bitcoin to your bitcoin address.Cryptography and the use of public and private keys solves the security issue when we use the internet.
Q1A. A public key is what you want other to see so you and others are able to exchange data. A private key is what you keep to yourself so only you have control of your data.
Q2. One use for public key cryptography is for a unique digital signature and a second is for encryption.

A private key is a very long, random number. As they are so long, it is very unlikely, that two persons/computers come up with the same private key. A public key is mathematically derived from the private key. This is why the two numbers are a “Public/Private-Key-Pair”

Private keys are randomly selected numbers that are used to create a public key. The private key is supposed to be kept solely for the user that created it and can verify identity of the user but the public key is broadcast to anyone that wants it for encryption purposes.

Two uses are encryption and digital signature, the latter being used more in bitcoin.

HI,
1, Private key provides full access/control over a specified address (like account) to everyone who knows it (so dont share it) and public key is like public address created from it. If someone wants to send data to me, he will use public key. Data are encrypted using public key and can be decrypted only by related private key.
2, Its used as address visible to all, encryption and as digital signature.

- A private key is a randomly generated unique number that is associated to a specific person, while the public key is the outcome produced by using said private key as an input for a certain mathematical function.
Then, the public key can be used as the basis for the encryption of some kind of information, making it possible only for the owner of the associated private key to decrypt its content.
It can also be used in digital signatures, because the owner of both keys can use the private key to hash a document, generating a signature that can then be transferred and verified by using the associated public key and the hash function on the document and the signature, to check if both would provide with the same resulting value. - As explained above, two possible use cases are digital signatures and encryption.

- The public key is like an email address, it is open to the public to see. By sending information to the public key you are encrypting the data. In order to view or decrypt the information sent to the public key you have to have the private key that is linked to the public key.
- encryption (sending information over an unsecure network)
digital signatures (how you can identify who sent the message)

What 2 use-cases can public key cryptography be used for?
2. Encryption and digital signatures. It is mostly used for digital signatures.
In encryption, the sender reads the public key of the recipient, then uses it to encrypt their message. At this point only the sender can know what is in the message if intercepted as it is gibberish to anyone else. The receiver then takes the message encrypted with the receivers public key and decrypts it using the algorithm that created it from their private key.
In digital signatures, the sender uses their private key to create a signature. The receiver of the digital signature can then use this against the senders public key to verify the signature of the sender. This digital signature is used in bitcoin.
In bitcoin, when a wallet is created it generates a random number - the private key. From this is created the public key, and again from this is generated the bitcoin wallet address. To send the sender must (as above) use the private key to create a signature.
