+# pkce-challenge
+
+Generate or verify a Proof Key for Code Exchange (PKCE) challenge pair.
+
+Read more about [PKCE](https://www.oauth.com/oauth2-servers/pkce/authorization-request/).
+
+## Installation
+
+```bash
+npm install pkce-challenge
+```
+
+## Usage
+
+Default length for the verifier is 43
+
+```js
+import pkceChallenge from "pkce-challenge";
+
+await pkceChallenge();
+```
+
+gives something like:
+
+```js
+{
+    code_verifier: 'u1ta-MQ0e7TcpHjgz33M2DcBnOQu~aMGxuiZt0QMD1C',
+    code_challenge: 'CUZX5qE8Wvye6kS_SasIsa8MMxacJftmWdsIA_iKp3I'
+}
+```
+
+### Specify a verifier length
+
+```js
+const challenge = await pkceChallenge(128);
+
+challenge.code_verifier.length === 128; // true
+```
+
+### Challenge verification
+
+```js
+import { verifyChallenge } from "pkce-challenge";
+
+(await verifyChallenge(challenge.code_verifier, challenge.code_challenge)) ===
+  true; // true
+```
+
+### Challenge generation from existing code verifier
+
+```js
+import { generateChallenge } from "pkce-challenge";
+
+(await generateChallenge(challenge.code_verifier)) === challenge.code_challenge; // true
+```
