+
+Pure JavaScript/TypeScript implementation of the Ed448 elliptic curve (RFC 8032) for EdDSA signature. Uses the `jsbn` library for big integer operations. Uses `jssha` for `SHAKE256` hash calculation.
+
+## Installation
+
+Using `npm`:
+
+    npm install ed448-js
+
+or `yarn`:
+
+    yarn add ed448-js
+
+Then include it in your code:
+
+```ts
+import createEd448 from "ed448-js";
+```
+
+## Usage
+
+```ts
+const Ed448 = createEd448();
+```
+
+### `getPublicKey(privateKey)`
+
+Calculate public key from a provided private key
+
+```ts
+const privateKey = Array.from(crypto.randomFillSync(new Uint8Array(57)));
+const publicKey = Ed448.getPublicKey(privateKey);
+```
+
+The private key can be any random generated byte-array of length 57
+
+### `sign(privateKey, publicKey, message, context?): number[]`
+
+Calculate the EdDSA signature.
+The result is represented as plain number array (length: 114). It can be converted using `Buffer.from`, or `Uint8Array.from`.
+
+### `verify(publicKey, message, signature, context?): boolean`
+
+Verify the EdDSA signature.
