    About Lesson

    Cryptography is a technique for protecting data from unwanted access. Cryptography is used in blockchain to safeguard transactions between two nodes in a blockchain network. This component assures the security, integrity, and verification of information stored in the ledger or exchanged between nodes.

    Cryptography has come up with encryption methods that cannot be broken, these encryption methods include;

    • Symmetric encryption: this is a type of encryption that is used to secure data, in which the encryption and decryption of data use a similar key. The key should be kept secret since it is used to decrypt data. Both the sender and the receiver require a mechanism to exchange keys before exchanging data.
    • Asymmetric encryption: this is a type of encryption that is used to secure data, in which both the encryption and the decryption of data use two different keys. The key which is used to encrypt the data is referred to as the public key while the key used to decrypt the data is referred to as the private key, which is essential for security to secure the rights of the receiver.
