### 🔑 JWT Secret Key Generator

The JWT Secret Key Generator lets you instantly generate secure, random secret keys for signing your JSON Web Tokens ([JWTs](https://jwtsecrets.com/#generator)).

**How to use:**

* Choose the key length (e.g., 256 bits, 512 bits).
* Select the output format (Base64 or HEX).
* Click “Generate”.
* Copy and use the key in your application.

✅ **Tip:** Always keep your secret keys private and rotate them regularly (see JWT Key Rotation Tool).

***

### 🧩 JWT Decoder

Use the JWT Decoder to quickly decode and inspect the contents of a JWT without validating the signature.

**How to use:**

* Paste your JWT into the input box.
* Instantly view the **Header**, **Payload**, and **Signature** sections.
* Check the claims like `exp`, `iat`, `sub`, etc.

⚠ **Note:** This tool does **not** validate the token; it only decodes it.

***

### ✏️ JWT Encoder

The [JWT Encoder](https://jwtsecrets.com/tools/jwt-encode) allows you to create JWTs for testing or development.

**How to use:**

* Fill in your header and payload fields.
* Enter your secret key.
* Select the signing algorithm (HS256, HS512, etc.).
* Click “Encode” to generate the JWT.

🎯 **Use case:** Test how your app handles specific claims or tokens.

***

### 📜 JWK Generator

A JWK Generator creates JSON Web Key (JWK) objects that represent your public keys.

**How to use:**

* Choose your key type (RSA or EC).
* Click “Generate”.
* Copy the JWK to use in your JWKS endpoint or app.

🛡 **Benefit:** Automates the creation of public keys for distributed systems.

***

### 🔐 Public & Private [Key ](https://jwtsecrets.com/tools/api-key-generator)Pair Generator

The Public & Private Key Pair Generator helps you create asymmetric keys (RSA or EC).

**How to use:**

* Choose the algorithm and key size.
* Click “Generate”.
* Download or copy the private and public keys.

🔑 **Tip:** Use the private key to sign JWTs and the public key to verify them.

***

### ♻️ JWT Key Rotation Tool

The JWT Key Rotation Tool helps automate and manage secret key rotation.

**How to use:**

* Configure a rotation interval (e.g., weekly).
* Store old keys for backward compatibility.
* Replace old keys in your app with new ones.

🛡 **Benefit:** Keeps your tokens secure by limiting the lifetime of a single key.

***

### 📊 Audit & Validation Tool

The Audit & Validation Tool allows you to check JWT signatures and validate claims.

**How to use:**

* Paste your JWT and provide the expected secret/public key.
* Click “Validate”.
* See if the signature is correct and if claims like `exp` or `nbf` are valid.

✅ **Use case:** Ensure your production tokens are correctly issued and safe.
