  1. Public and private key pairs are elements used for encryption of data, where the public key is derived from the private key using a mathematical function, the first being useful for public verification, and the last needed to be kept safe with the owner since in hold of both keys one can perform certain encryption/decryption processes, making information available/readable for only who is desired even if exchanged in public channels.
  2. Public-private key pairs major use cases are 1) encryption (for ie to send secure/secret messages through an open channel that only a trusted person can decrypt) and 2) digital signatures (for ie, checking integrity, meaning verifying if an information or a file was written/sent by a specific someone/original source and it wasn’t tampered with).

1). First of all, the private key, is a long string of random numbers that is generated by your wallet/computer, this random set of numbers generate your public key which in return creates or hashes a btc address.

The concept of a public and private keys is a person will be able to send and receive sensitive information on the internet without any third party or unauthorized personal being able to read/write or even steal your information or data.

Public key encrypts the information and the private key is to decrypted the information that was encrypted by the public key.

2). The two use cases would be encryption (Security and privacy) and digital signatures (Verification).
