Struct Cmp20 

pub struct Cmp20;

CMP20 threshold-ECDSA over P-256. Use for new threshold signing deployments; GG18 is provided for interop with existing systems.

Implementations

impl Cmp20

pub fn keygen(threshold: u32, party_count: u32) -> NapiResult<Cmp20Keygen>

Run a non-interactive CMP20 DKG for party_count parties at threshold threshold. Returns the per-party share blobs and the joint SEC1-compressed public key.

pub fn sign( shares: Vec<Buffer>, threshold: u32, message: Buffer, ) -> NapiResult<Buffer>

Threshold-sign message using shares (each a share blob from a previous keygen call). Returns the 64-byte (r, s) signature.

pub fn sign_batch( shares: Vec<Buffer>, threshold: u32, messages: Vec<Buffer>, ) -> NapiResult<Vec<Buffer>>

Sign N messages against the same joint key without re-running DKG. See sign_batch in the Rust crate for performance notes.

Trait Implementations

impl FromNapiMutRef for Cmp20

unsafe fn from_napi_mut_ref( env: napi_env, napi_val: napi_value, ) -> Result<&'static mut Self>

This function called to convert napi values to native rust values

impl FromNapiRef for Cmp20

unsafe fn from_napi_ref( env: napi_env, napi_val: napi_value, ) -> Result<&'static Self>

This function called to convert napi values to native rust values

impl JavaScriptClassExt for Cmp20

fn into_instance<'scope>( self, env: &'scope Env, ) -> Result<ClassInstance<'scope, Self>>

fn into_reference(self, env: Env) -> Result<Reference<Self>>

fn instance_of<'env, V: JsValue<'env>>(env: &Env, value: &V) -> Result<bool>

impl ObjectFinalize for Cmp20

fn finalize(self, env: Env) -> Result<(), Error>

impl ToNapiValue for Cmp20

unsafe fn to_napi_value(env: napi_env, val: Cmp20) -> Result<napi_value>

This function called to convert rust values to napi values

fn into_unknown(self, env: &Env) -> Result<Unknown<'_>, Error>

impl TypeName for Cmp20

fn type_name() -> &'static str

fn value_type() -> ValueType

impl TypeName for &Cmp20

fn type_name() -> &'static str

fn value_type() -> ValueType

impl TypeName for &mut Cmp20

fn type_name() -> &'static str

fn value_type() -> ValueType

impl TypeTag for Cmp20

fn type_tag() -> napi_type_tag

Returns this class’s stable per-type tag. The derive computes it from the class’s content identity string (crate@version::module_path::ClassName), which is fixed for a given class, so repeated calls return the same tag.

impl ValidateNapiValue for &Cmp20

unsafe fn validate(env: napi_env, napi_val: napi_value) -> Result<napi_value>

This function called to validate whether napi value passed to rust is valid type.

impl ValidateNapiValue for &mut Cmp20

unsafe fn validate(env: napi_env, napi_val: napi_value) -> Result<napi_value>

This function called to validate whether napi value passed to rust is valid type.
