Struct Ed25519Credential 

pub struct Ed25519Credential { /* private fields */ }

Binance Ed25519 credentials for WebSocket API authentication.

Ed25519 is required for WebSocket API authentication (session.logon). This is the only key type supported for execution clients.

Implementations

impl Ed25519Credential

pub fn new( api_key: String, private_key_base64: &str, ) -> Result<Self, Ed25519CredentialError>

Creates a new Ed25519Credential from API key and base64-encoded private key.

The private key can be provided as:

• PKCS#8 DER format (48 bytes, as generated by OpenSSL)
• PEM format (with or without headers)

Raw 32-byte Ed25519 seeds (without PKCS#8 wrapping) are rejected: every 32-byte value is a mathematically valid seed, so accepting them would silently misclassify any base64-decodable HMAC secret as Ed25519.

For PKCS#8/PEM format, the 32-byte seed is extracted from the last 32 bytes.

Errors

Returns an error if the private key is not valid base64, does not carry the Ed25519 PKCS#8 OID, or is shorter than 32 bytes after decoding.

pub fn api_key(&self) -> &str

Returns the API key.

pub fn sign(&self, message: &[u8]) -> String

Signs a message with Ed25519 and returns a base64-encoded signature.
