EXAMPLES
Hashes whatever you give it with keccak256:
cast keccak "I tried auditioning at the foundry, but they said: Sorry, we only cast iron."0x83ee1d1103f1f612ae164e30f597409cbebed0c5168f31b12cce1a0fc0f90bf3
Useful for getting the function selector of a function signature. Just pass the function signature as a string and get the first 4 bytes of the hash:
cast keccak "transfer(address,uint256)"0xa9059cbb2ab09eb219583f4a59a5d0623ade346d962bcd4e46b11da047c9049b
Works with hex values too:
cast keccak 0x12340x56570de287d73cd1cb6092bb8fdee6173974955fdef345ae579ee9f475ea7432
