Add Example For Poseidon Hash Function

[AtropineTears]

Hello,

Could you add an example for producing a proof of the preimage with the Poseidon Hash Function. It would be much appreciated.

Thank you

Hi! You can find some examples in the test case: https://github.com/meilof/pysnark/pull/27/files#diff-4d13c5e2b571a105adadc440b54a9aeffe260b317e9fe8bd17d89ba9467d2e84. I hope that helps!

Hi,

Can you help me? I am trying to implement proving a Poseidon preimage hash but cannot seem to get it to work right.

I am looking at input of 32 bytes that will be hashed and proving that the prover knows the 32 bytes.

Thank you!

Is the text example hashing:

0, 1, 2, 3,4

I would like to see a method of hashing a byte string

Did you try running the test cases from https://github.com/meilof/pysnark/blob/master/test/test_poseidon_hash.py? Did you try running a simple example program such as https://github.com/meilof/pysnark/blob/master/examples/cube.py? What is going wrong?

Yes,

Can you add Poseidon to the /examples/ folder. I want to see an example of it.

An example would be of proving you know:

preimage, for example

I don't know much of python so it is hard of me to use it. I am trying to find out how to hash a preimage and prove it.
