In public key cryptography, a key pair refers to a set of two keys, namely a private key and a public key, that are mathematically related to each other. The public key is used to encrypt data, while the private key is used to decrypt the same data. This process is known as asymmetric encryption.
Key pairs are commonly used in cryptocurrency to manage access control. The public key is shared with others to receive cryptocurrency, while the private key is kept secure and confidential to authorize transactions and transfers from the cryptocurrency wallet. It is essential to protect the private key to prevent unauthorized access to the wallet and ensure the security of the cryptocurrency assets.
In summary, a key pair in public key cryptography is a set of two keys, a private key, and a public key, that are mathematically linked to each other. They are used in asymmetric encryption and play a crucial role in controlling access to cryptocurrency by securing the wallet through the use of the private key.
