In this case, data is encrypted using a secret key and then both the encoded message and secret key are sent to the recipient for decryption. Clearly, the word Crypto represents (secret), and Graph also represents (write). Therefore, this can be visible in the sense that the medium through which information are been sent and processed through the sender or receiver without the prevention of any intermediary and it forms an unknown ecosystem in which transactions are encoded and protected by a single other. Cryptograghy helps in verification and transactions procedures, which normally effect inside every users and offers a signature such as layout for every transactions. # ***The three (3) types of Cryptograghy:*** **Cryptograghy can be broken down into there (3) Different types.**👇🏽👇🏽 ▪️ Secret key Cryptograghy ▪️ Public key Cryptograghy and ▪️ Hash Functions. ![cyxkEVqiiLy2ofdgrJNxeZC3WCHPBwR7MjUDzY4kBNr81LetETmuDWKvqCPmaSADqzr7cvw5uMJgEuBeuvuxazYG8zoQXWgA6qkN5Yo32DcRzka1VLsrb2BJSkBrF9yjpHU.png](https://cdn.steemitimages.com/DQmRDGakkjKoaVympAAufuzPBV4RV5JAPaBNHW5UvyKR6qr/cyxkEVqiiLy2ofdgrJNxeZC3WCHPBwR7MjUDzY4kBNr81LetETmuDWKvqCPmaSADqzr7cvw5uMJgEuBeuvuxazYG8zoQXWgA6qkN5Yo32DcRzka1VLsrb2BJSkBrF9yjpHU.png) # Q2b: HOW DOES IT MAKE CRYPTOCURRENCIES SECURE ![cyxkEVqiiLy2ofdgrJNxeZC3WCHPBwR7MjUDzY4kBNr81LetETmuDWKvqCPmaSADqzr7cvw5uMJgEuBeuvuxazYG8zoQXWgA6qkN5Yo32DcRzka1VLsrb2BJSkBrF9yjpHU.png](https://cdn.steemitimages.com/DQmRDGakkjKoaVympAAufuzPBV4RV5JAPaBNHW5UvyKR6qr/cyxkEVqiiLy2ofdgrJNxeZC3WCHPBwR7MjUDzY4kBNr81LetETmuDWKvqCPmaSADqzr7cvw5uMJgEuBeuvuxazYG8zoQXWgA6qkN5Yo32DcRzka1VLsrb2BJSkBrF9yjpHU.png) Cryptography has its reason of coded data, and it guarantees that all data or informations can be be able to run through, from one nodes to other secret from the general public and has been made feasible with the keys of coded data and may simplest be utilized by the legal receiver to access, process, decode and encoded informations on it normal format.

Cryptocurrencies is now a popular digital financial transactions. It is a form of payment that can be trade online for goods and services which doesn't rely on banks and it's policy. Cryptocurrency has definitely grow to become a well known currency of exchange in the world and this wouldn't have been achieveable without the help of Cryptograghy. We all should endeavour to join the moving train "crpto" now so as not to be left behind. ![3W72119s5BjVs3Hye1oHX44R9EcpQD5C9xXzj68nJaq3CeTzrkuKNGmm2EurZ9XMRAk6ziVbheyaXvW2ZXWoA99oRpZ8v1ycqB9MAxhJNMmbtdAA9TottW.png](https://cdn.steemitimages.com/DQmYkiCHfNLSARwH7H5eqU9m6TMrMbdR7cZ6vuCwxYydVqP/3W72119s5BjVs3Hye1oHX44R9EcpQD5C9xXzj68nJaq3CeTzrkuKNGmm2EurZ9XMRAk6ziVbheyaXvW2ZXWoA99oRpZ8v1ycqB9MAxhJNMmbtdAA9TottW.png) **I most be open, this lecture by professor @awesononso is absolutely wonderful, it has really increased my knowledge in cryptocurrency and beyond.
