Struct DeclarePaperCodeParams 

pub struct DeclarePaperCodeParams {
    pub argon2id_hash: Vec<u8>,
    pub salt: Vec<u8>,
    pub params: Option<Argon2idParams>,
}

Declare a paper-code (mnemonic) recovery method (kind=paper_code). The plaintext mnemonic is generated client-side and NEVER transmitted — only the argon2id verifier, its salt, and the KDF params are sent. The server MUST reject any request that carries plaintext mnemonic bytes. weft#186.

Fields

argon2id_hash: Vec<u8>

argon2id(mnemonic, salt, params). Raw hash bytes.

salt: Vec<u8>

Per-row random salt the client used. Stored so SubmitRecoveryProof can tell the recovering client which salt to hash against.

params: Option<Argon2idParams>

KDF params stored alongside the hash so they can be tuned without breaking existing codes. Floor per OWASP: 64 MiB memory, 3 iterations, parallelism 4.
