Trait Signer 

Source 
pub trait Signer:
    Identified
    + Send
    + Sync {
    // Required methods
    fn sign(&self, message: &[u8], private_key_hex: &str) -> Result<String>;
    fn verify(
        &self,
        message: &[u8],

        public_key_hex: &str,
    ) -> Result<()>;
}
Expand description

签名：消息签名与验签。密钥与签名均为十六进制，格式由实现决定 （本项目内统一：ECDSA / SM2 为定长 r‖s，Ed25519 为 64 字节定长）。

Required Methods§

Source

fn sign(&self, message: &[u8], private_key_hex: &str) -> Result<String>

对消息签名，返回十六进制签名（失败不为原因分类）。

Source

fn verify( &self, message: &[u8], signature_hex: &str, public_key_hex: &str, ) -> Result<()>

验签；失败与格式错误一律 crate::error::Error::VerificationFailed（不区分原因）。

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
