@cryptkeeperzk/semaphore-identity v3.10.3
| This library provides a class that can be used to create identities compatible with the Semaphore circuits. Each identity contains two secret values: trapdoor and nullifier, and one public value: commitment. The Poseidon hash of the secret values is the identity secret, and its hash is the identity commitment. |
