#### 加密流程
|

```plaintext

明文 → Deflate压缩 → AES256-CTR加密 → ChaCha20-Poly1305加密 → Base64编码 → 密文

## 😕 疑问
|
||||
|
||||
##### 发送给多人如何管理多个密码？
|
||||
#### 发送给多人如何管理多个密码？如何安全地传递密码？
|
||||
|
||||
- 使用可靠的密码管理器，例如：**KeePass**、KeePassXC、**Bitwarden**
|
||||
- 使用**开源的阅后即焚文档**传递密码，例如：**PrivateBin**、pastebin
|
||||
|
||||
##### 少量文字也会生成较长的文本，能缩短吗？
|
||||
#### 少量文字也会生成较长的文本，能缩短吗？
|
||||
|
||||
- 因为**追求安全性**，所以添加了随机盐、Nonce等参数，密文中存储这些参数导致的；去掉参数**追求短密文会削弱安全性**，所以无短密文计划。
|
||||
- 因为**追求安全性**，所以添加了随机种子、校验标签参数，密文中存储这些参数导致的；去掉参数**追求短密文会削弱安全性**，目前已做到保障安全性的情况下最短了。
|
||||
|
||||
##### 未来还会添加的算法？
|
||||
#### 感觉加密/解密慢？
|
||||
|
||||
- 暂定密钥派生使用**Argon2id**，加密算法使用三种进行级联。
|
||||
- 使用**Argon2id算法(慢哈希算法)**的正常现象；Base64模式下，短文本理应1秒内加/解密完成，5M的文本（大约200万字）应3秒左右，这是可以接受的速度。
|
||||
|
||||
##### 为什么不使用PBKDF2-SHA512？
|
||||
|
||||
- 如果使用`PBKDF2-SHA512`迭代50万次，加密短文本也会感到明显的延迟，而`PBKDF2-SHA256`能平衡速度与安全。
|
||||
|
||||
##### 感觉加密/解密慢？
|
||||
|
||||
- PBKDF2迭代50万次所以慢，是正常现象；短文本理应1秒内加/解密完成，5M的文本3秒左右，这是可以接受的速度。
|
||||
|
||||
##### 支持加密/解密的最大容量？
|
||||
#### 支持加密/解密的最大容量？
|
||||
|
||||
- 不影响速度的情况下，**建议5M以下**（测试支持50M+）；超大的文本请使用压缩包或者其它方式加密。
|
||||
|
||||
##### 可以给密文再次加密？
|
||||
#### 可以给密文再次加密？或者嵌入？
|
||||
|
||||
- `明文 → emoji密文 → 中文密文 → ......` 可以这样无限套娃，但不会增加安全性，安全性取决于你的密码，因此不建议这样做。
|
||||
- `明文 → emoji密文 → 中文密文 → ......` 可以这样无限套娃加密，但不会增加安全性，安全性取决于你的密码，因此不建议这样做。
|
||||
- **中文密文**嵌入**零宽密文**，会优先解密零宽，达成一文双解的效果，但并不能瞒过机器识别。
|
||||
|
||||
##### 经过某些软件发送密文后，解密错误？
|
||||
#### 经过某些软件发送密文后，解密错误？
|
||||
|
||||
- 是因为**某些软件喜欢折叠聊天内容**，或者发送过长的密文被截断，建议你检查密文的完整性；Eomij密文可能因为不同设备内置的表情不一导致解密错误，零宽密文有被某些平台过滤字符的可能。
|
||||
|
||||
##### 零宽密文只有两个字符？可见字符可以自定义？
|
||||
#### 零宽密文只有两个字符？可见字符可以自定义？
|
||||
|
||||
- 密文总长度没有变，只是**转为不可见字符藏在两个可见字符中间**，是为了让人知道密文在哪，方便复制。
|
||||
- 可以，只需**手动替换**密文中的可见字符（零宽密文**只是对人不可见**，机器是秒识别的，但识别不代表能解密）。
