Trait KeyAgreement 

Source 
pub trait KeyAgreement:
    Identified
    + Send
    + Sync {
    // Required method
    fn agree(
        &self,
        private_key_hex: &str,
        peer_public_key_hex: &str,
    ) -> Result<String>;
}
Expand description

密钥协商：以己方私钥与对方公钥导出共享秘密（ECDH / X25519）。

Required Methods§

Source

fn agree( &self, private_key_hex: &str, peer_public_key_hex: &str, ) -> Result<String>

返回定长共享秘密的十六进制（长度由实现决定，如 X25519 为 64 位十六进制）。

共享秘密是原始 DH 输出，不应直接当密钥使用：请先经 KDF 派生 （本库自带 KeyDerivation / HKDF）。

Dyn Compatibility§

This trait is dyn compatible.

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