ConfigEncryption

Struct ConfigEncryption 

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

配置加密器:使用 XOR + Base64 对敏感配置值进行对称加密

适用场景:数据库密码、API Key 等敏感配置不应明文存储在配置文件中。 加密格式:ENC(base64(xor(plaintext, key)))

Implementations§

Source§

impl ConfigEncryption

Source

pub fn new(key: impl Into<String>) -> Self

Source

pub fn encrypt(&self, plaintext: &str) -> String

加密明文,返回 ENC(base64) 格式字符串

Source

pub fn decrypt(&self, ciphertext: &str) -> Result<String, String>

解密 ENC(base64) 格式字符串,返回明文

Source

pub fn is_encrypted(value: &str) -> bool

判断值是否已加密(以 ENC( 开头)

Source

pub fn decrypt_if_needed(&self, value: &str) -> Result<String, String>

如果值已加密则解密,否则原样返回

Source

pub fn decrypt_config( &self, config: &HashMap<String, String>, ) -> Result<HashMap<String, String>, String>

批量解密配置 map 中所有已加密的值
