Add HashWithState to increase its scalability #60

Closed hunshenshi closed 6 months ago

jeffprestes commented 8 months ago

Please do not get me wrong on the question, but in which real-world situation would this initial state be helpful? The previous results of other hash would be enough, wouldn't they?

hunshenshi commented 8 months ago

consistent with circomlibjs. In this way, the results of the two poseidon hash can be consistent. Thank you for your review.

+1, this would be useful for us too. When hashing more than 16 values, it can be useful to chain hashes together, such that the hash of the last 16 values is the initial state of the next 16. Opened #61 before seeing this one.
