Learning Solidity (0.5) - Hash Function (Keccak256)

Keccak256 is a cryptographic hash function available in Solidity. In this video, I will show you how you can create a guessing game using the hash function. Moreover, there is a way to create a hash collision using abi.encodePacked that you should definitely be aware of so that you don't make this critical mistake in your smart contract.
