pub struct Ed25519Auth { /* private fields */ }

Ed25519 authentication implementation for exchanges

Implementations

impl Ed25519Auth

pub fn new(signing_key: SigningKey, api_key: SmartString) -> Self

Create new Ed25519 authenticator with existing signing key

pub fn from_secret_key_hex( secret_hex: &str, api_key: SmartString, ) -> Result<Self>

Create Ed25519 authenticator from hex-encoded secret key

Arguments

• secret_hex - 64-character hex string representing the 32-byte secret key
• api_key - API key identifier for the exchange

Errors

Returns error if the hex string is invalid or not 64 characters

pub fn sign_params(&self, params: &[(&str, &str)]) -> Result<SmartString>

Sign query parameters using Ed25519

Creates a query string from parameters and signs it using Ed25519. Parameters are URL-encoded and joined with ‘&’ separator.

Arguments

• params - Key-value pairs to sign

Returns

Hex-encoded Ed25519 signature

pub fn sign_request( &self, _method: &str, _path: &str, _body: Option<&str>, ) -> Result<FxHashMap<SmartString, SmartString>>

Sign a complete HTTP request

Creates authentication headers for an HTTP request including the signature. The signature is computed over the request parameters.

Arguments

• method - HTTP method (GET, POST, etc.)
• path - Request path
• body - Optional request body (currently unused but reserved for future use)

Returns

HashMap containing authentication headers

pub fn api_key(&self) -> &str

Get the API key

pub fn public_key_hex(&self) -> SmartString

Get the public key as hex string

pub const fn signing_key(&self) -> &SigningKey

Get the signing key reference (for advanced use cases)

pub const fn verifying_key(&self) -> &VerifyingKey

Get the verifying key reference (for advanced use cases)
