The process of encoding data to prevent unauthorized access.
Encryption is a method by which information is converted into secret code that hides the information's true meaning. In computing, unencrypted data, also known as plaintext, is encrypted using an encryption algorithm and an encryption key. This process generates ciphertext that can only be viewed in its original form if it is decrypted with the correct key. Cryptocurrencies use encryption to secure transactions and control the creation of new coins.
Cryptocurrencies like Bitcoin use encryption techniques to regulate the generation of units and verify transfers.
