Struct AgreementMethod 

pub struct AgreementMethod {
    pub algorithm: KeyAgreementAlgorithm,
    pub method: Option<KeyDerivationMethod>,
    pub nonce: Vec<u8>,
    pub legacy_digest: Option<String>,
    pub originator: Option<KeyInfo>,
    pub recipient: Option<KeyInfo>,
}

Public agreement descriptor. Key information is advisory; a document never supplies the application’s private handle or chooses its security profile.

Fields

algorithm: KeyAgreementAlgorithm

Exact agreement mechanism, independently permission checked at execution.

method: Option<KeyDerivationMethod>

Explicit derivation; omission requires application knowledge except for the legacy DH algorithm, whose derivation is specified by its URI.

nonce: Vec<u8>

Public agreement nonce, retained in the trusted descriptor comparison. Legacy DH incorporates it directly; explicit KDFs use their own context fields rather than an undocumented nonce concatenation.

legacy_digest: Option<String>

Optional legacy DH digest. No default digest is guessed.

originator: Option<KeyInfo>

Originator public key or application lookup hints in the original role.

recipient: Option<KeyInfo>

Recipient lookup hints, never permission to substitute a private key.

Implementations

impl AgreementMethod

pub fn derive_key( &self, consuming_algorithm: &str, output_len: usize, key: &dyn KeyAgreementKey, peer: &[u8], provider: &dyn CryptoProvider, budget: &mut KeyEstablishmentBudget<'_>, ) -> Result<Zeroizing<Vec<u8>>, XmlEncError>

Establish a consuming key with explicitly bound private and peer keys. The caller validates party identities before invoking this method.
