translate-witness

This command can be used to translate extended witnesses (outputs of GenerateWitness or SplitWitness) from REP3 to 3-party Shamir secret sharing.

Example

co-noir translate-witness --witness test_vectors/poseidon/poseidon.gz.shared --src-protocol REP3 --target-protocol SHAMIR --config configs/party.toml --out test_vectors/poseidon/shamir_poseidon.gz.shared

Here, poseidon.gz.shared is the REP3 input share, shamir_poseidon.gz.shared the Shamir output share, and party.toml is a network configuration.
