Cryptography has been used for thousands of years to hide messages and keep sensitive information confidential. In cryptography, messages and information are encoded so that only the intended person can read them. Today, cryptography is used in bank cards, computer passwords, and e-commerce to secure your transactions.

Cryptography is critical to protect you and your data, ensuring confidentiality, and preventing cyber criminals from misusing sensitive information. There are four main purposes of cryptography:

  • Confidentiality
  • Integrity
  • Non-repudiation
  • Authentication

This technique of secure communication is used to encrypt data stored in the blockchain. Thus, many users of cryptocurrencies and blockchain technology are confident that their data and privacy are protected.
