Function hmac_sign 

pub fn hmac_sign(
    message: &str,
    secret: &str,
    algorithm: HashAlgorithm,
    digest: DigestFormat,
) -> Result<String>

Generates an HMAC signature for a message.

Arguments

• message - Message to sign
• secret - Secret key for HMAC
• algorithm - Hash algorithm to use
• digest - Output encoding format

Returns

Encoded signature string.

Errors

Returns error if algorithm is not supported for HMAC.

Examples

use ccxt_core::auth::{hmac_sign, HashAlgorithm, DigestFormat};

let signature = hmac_sign(
    "test message",
    "secret_key",
    HashAlgorithm::Sha256,
    DigestFormat::Hex
).unwrap();
