checksum static method
Calculates the checksum of the given payload using the first 4 bytes of its SHA3-256 hash.
payload
- A list of integers representing the payload to be hashed.
Implementation
static List<int> checksum(payload) {
var k = SHA3(256, SHA3_PADDING, 256);
k.update(payload);
List<int> hash = k.digest();
return hash.sublist(0, 4);
}
