core::starknet::syscalls::keccak_syscall

• The input must be a multiple of 1088 bits (== 17 u64 words)
• The input must be pre-padded following the Keccak padding rule (pad10*1):
  1. Add a ‘1’ bit
  2. Add zero or more ‘0’ bits
  3. Add a final ‘1’ bit The total length after padding must be a multiple of 1088 bits
