encryption::encryptor

Struct SodiumXChaCha20Encryptor 

Source 
pub struct SodiumXChaCha20Encryptor { /* private fields */ }
Expand description

XChaCha20-Poly1305 加密器。

密钥实例在构造时就建立，加密与解密都复用它；密钥字节随 ChaChaPoly1305 自身的 Drop 清零。192 位 nonce 随机生成，单密钥下可安全处理海量消息 （salsa20 的 64 位 nonce 达不到这一点，见其模块文档）。

Source§

fn quirk(&self, value: Quirk) -> Painted<&T>
