Module identity 

Cryptographic identity management: BJJ keypairs (note ownership), X25519 keypairs (mixnet routing), and hierarchical DarkAccount key derivation.

Structs

BjjKeypair

BJJ keypair (Baby Jubjub curve). Note: BjjSecretKey (ark_ed_on_bn254::Fr) does not implement Zeroize – keypairs are short-lived and never persisted.
