I've updated the PR for circomlib 1.0 and circom 2.0. |
|
Any reason this hasn't been merged @weijiekoh? |
No particular reason that I know of. |
|
Does this PR just need to be re-targeted against circomlibjs instead? Edit: Looks like the downstream PLONK optimizations also need to be rebased in. Downstream also split the Poseidon permutations out slightly different. |

This PR implements Poseidon encryption and decryption following this spec:
https://drive.google.com/file/d/1EVrP3DzoGbmzkRmYnyEDcIQcXVU7GlOd/view
It also refactors the Poseidon permutation function to allow the Poseidon hash function to share code with the encryption/decryption functions.
Circuits and tests are also included.
