Public and private keys are almost like an extremely secure username and password. Your public key is used sort of like a username to share with everyone so they can contact or make transactions with you. Your private key like a password should be kept only to you and is what is needed to access those messages and transactions in order to view and complete them.

Encryption and digital signatures are the two use cases of public and private key cryptography. Encryption for sending secretive messages you donāt want anyone to see. Digital signatures to confirm your identity to others so you know you are getting what you got from who you think it is.

Q: Describe the concept of public and private key with your own words.
A: a Private Key is basically a random number which can be used to generate a Public Key. The Private Key can be used to sign a SEND transaction, and Public Key can be used to verify something you received is from a Particular person (you use that persons Public Key)

1 Private keys are used to encrypt/decrypt messages. Private keys are random numbers that are hashed to obtain public keys. Only the holders of private keys are able to get the public key through a hash. This allows digital signatures and verification.
2 The uses of this are enabling secure digital signatures and verifying all transactions.

Private key is a generated random number. If you own the private key, you own everything which is under the private key. It is secret code that nobody else knows. From this private key is public key derived according to a formula. Public key is basically used for data exchange with others and others can see it. Public key can be derived from private key, but not visa versa.

Public key can be used for encrypting the message and only private key (from which was public key derived) can read this message. Second use-case is for digital signiture - digital signiture is created with private key and you can compare the public key with the signiture to verify the person.

So your computer generates a random number which is huge, this is your private key. From here your public key is derived mathematically from your private key. So your private key is to be kept very safe and your public key is the one that you an use on the internet. -

Private and public keys are a means to encrypt and decrypt data. The public key is used (hashed?) to encrypt the data. In order to decrypt one must be in possession of the private key. Without the private key, it is in theory, impossible to decrypt.

A private key is one that only you have access to, it is randomly generated and through it a public key can be made. The public key is viewed by all and is when compared to the āsignatureā of the private key it assures the two are from the stated sender. Though the two show a connection, there is no way to decipher the private key by having access to only the public key.

- Private keys are made to secure information. Private key is not known to the public. A public key is created and paired to the private key and is used to transfer the information in a way that only the private key can open said information. The private key is generally a very large number. 2. Public key cryptography could be used to send lab results from a lab to a doctor. In bitcoin transactions are used with public key cryptography. Bitcoin is sent via a public key to the private key paired with it. If someone wanted to send me bitcoin I would give them my public key to initiate transaction, they would then send me bitcoin attached to that public key that only I could accept and use via my private key.

ļ»æļ»æPrivate keys are randomly generated numbers that are used to derive public keys. Private keys need to be kept secret. Public keys can be shared. Public keys are derived from private keys and this is a one way function. Private keys cannot be discovered with the use of public keys.
Public/Private key combinations are used to ensure privacy in messaging and communications. The sender knows the public key and uses it to hide the content of the message through encryption. Data from the sender is encrypted using the public key of the receiver of the message or transaction. The encrypted message is received and decoded by the private key of the recipient.
