+- Encrypted Communication
+- Streamlined Client-Server Integration
+- Development simplification
+- Key Generation
+- Powered by a solid library
+
+The library uses Node-RSA to create a bridge between server-client with encrypted communication, enabling secure end-to-end communication.
+
+![RSA Client Image](structure.png)
+
+## Example
+
+RSA Bridge Server Instance
+
+```js
+import { RSAServer } from "rsa-bridge";
+const rsa = new RSAServer({ bits: 1024 });
+
+app.use(
+  rsa.gate((req, res, next) => {
+    // your handler functions
+  })
+);
+```
+
+RSA Bridge Client Instance
+
+```js
+import { RSAClient } from "rsa-bridge";
+const rsa = new RSAClient({ bits: 1024 });
+
+rsa.connect();
+rsa.fetch(INPUT, OPTIONS);
+```
+
+### Installing
+
+```sh
+npm install rsa-bridge
+```
+
+#### Testing
+
+```sh
+npm test
+```
+
+---
+
+## Usage
+
+Its use is divided into an **client** instance (`RSAClient`) and an **server** instance (`RSAServer`).
+The **server instance** must expose the public key (`publish`) and have the middleware (`gate`) to inject RSA into the handler.
+The **client instance** must have the public key exposure endpoint (`connect`) to encrypt the data.
+
+#### Instantiating
+
+<a name="instantiating"></a>
+To instantiate the service on the server it is necessary to specify `bits` or `keys` that will be used.
+Below is an example of instantiating the model used both on the server and on the client
+
+```javascript
+import { BasicRSA } from "rsa-bridge";
+const rsa = new BasicRSA(BasicRSAConfig);
+```
+
+- **random** - <span style="color: purple;">BasicRSAConfig</span> - you can generate random keys by entering the `bits`
+
+```js
+{
+  bits: number;
+}
+```
+
+- **custom** - <span style="color: purple;">BasicRSAConfig</span> - you can specify your keys using the configuration below
+
+```js
+{
+  keys: {
+    private: string,
+    public: string,
+    ...
+  }
+}
+```
+
+### Client-side
+
+#### Instantiating
+
+The instance configuration is the same as found [here](#instantiating). Although it is possible, a `custom` key is <span style="color: red">not recommended</span> for clients.
+
+```javascript
+import { RSAClient } from "rsa-bridge";
+const rsa = new RSAClient(BasicRSAConfig);
+```
+
+#### Connect
+
+Obtains a connection to the server's RSA service, via the endpoint defined for public key exposure.
+The `PATH` must point to the address defined [here](#expose).
+
+```javascript
+rsa.connect(PATH);
+```
+
+#### Fetch
+
+Execute a request to the server using the encryption bridge.
+
+```javascript
+rsa.fetch(INPUT, OPTIONS).then(({ body, response }) => {
+  // decrypted data
+});
+```
+
+### Server-side
+
+#### Instantiating
+
+The instance configuration is the same as found [here](#instantiating).
+
+```javascript
+import { RSAServer } from "rsa-bridge";
+const rsa = new RSAServer(BasicRSAConfig);
+```
+
+#### Publish
+
+<a name="expose"></a>
+The public key must be exposed for the bridge to work. The method must be **`GET`**.
+
+```javascript
+app.get(PATH, rsa.publish);
+```
+
+- **path** - <span style="color: darkblue;">string</span> - the HTTP path
+
+#### Gate
+
+It can be used as a **middleware**, propagating the service to **all routes**
+
+```javascript
+app.use(rsa.gate);
+app.post("example", HANDLER);
+```
+
+It can also be used on a , as in the **single path**
+
+```javascript
+app.post("/example", rsa.gate(HANDLER));
+```
+
+#### Getting Data
+
+If the request passed the gate, the data sent in the body can be obtained
+
+```javascript
+app.use(rsa.gate);
+app.post("/example", (req, res) => {
+  req.body; // decrypted data
+});
+```
+
+#### Send
+
+The `send` function will be wrapped by the `gate` to encrypt the data before sending it to the client.
+Predecessors like `.json()` and `.status()` can be used as well.
+
+```javascript
+app.use(rsa.gate);
+app.post("/example", (req, res) => {
+  res.status(200).send(DATA); // L0SQ23.....
+});
+```
+
+The wrapped `res` will extend throughout the _request_ until the _response_, even with the use of `next()` for example.
+
+```javascript
+app.use(rsa.gate);
+app.use((req, res, next) => {
+  next();
+});
+app.use((req, res) => {
+  res.status(200).json(DATA); // L0SQ23.....
+});
+```
+
+### Basic RSA Functions
+
+#### Encrypt
+
+Returns encrypted data as `base64`
+
+```javascript
+const encrypted = rsa.encrypt(data);
+```
+
+#### Decrypt
+
+returns decrypted data as `utf8`
+
+```javascript
+const decrypted = rsa.decrypt(data);
+```
+
+#### encryptWithKey
+
+returns encrypted data as `base64` encrypted with a different key
+
+```javascript
+const encrypted = rsa.encryptWithKey(key, data, format?);
+```
+
+#### publicKey
+
+exports the node's public key. The default encoding is "UTF8" but can be changed.
+
+```javascript
+const publicKey = rsa.publicKey(KeyFormat, OutputEncoding);
+```
+
