+
+We have created a number of WebCrypto polyfills including: [node-webcrypto-ossl](https://github.com/PeculiarVentures/node-webcrypto-ossl), [node-webcrypto-p11](https://github.com/PeculiarVentures/node-webcrypto-p11), and [webcrypto-liner](https://github.com/PeculiarVentures/webcrypto-liner).  `webcrypto-core` was designed to be a common layer to be used by all of these libraries for input validation.
+
+Unless you intend to create a WebCrypto polyfill this library is probably not useful to you.
+
+## Installing
+
+```
+npm install webcrypto-core
+```
+
+## Example
+
+Current examples shows how you can implement your own WebCrypt interface
+
+```js
+const core = require(".");
+const crypto = require("crypto");
+
+class Sha1Provider extends core.ProviderCrypto {
+
+  constructor() {
+    super();
+
+    this.name = "SHA-1";
+    this.usages = [];
+  }
+
+  async onDigest(algorithm, data) {
+    const hash = crypto.createHash("SHA1").update(Buffer.from(data)).digest();
+    return new Uint8Array(hash).buffer;
+  }
+
+}
+
+class SubtleCrypto extends core.SubtleCrypto {
+  constructor() {
+    super();
+
+    // Add SHA1 provider to SubtleCrypto
+    this.providers.set(new Sha1Provider());
+  }
+}
+
+class Crypto extends core.Crypto {
+
+  constructor() {
+    this.subtle = new SubtleCrypto();
+  }
+
+  getRandomValues(array) {
+    const buffer = Buffer.from(array.buffer);
+    crypto.randomFillSync(buffer);
+    return array;
+  }
+
+}
+
+const webcrypto = new Crypto();
+webcrypto.subtle.digest("SHA-1", Buffer.from("TEST MESSAGE"))
+  .then((hash) => {
+    console.log(Buffer.from(hash).toString("hex")); // dbca505deb07e1612d944a69c0c851f79f3a4a60
+  })
+  .catch((err) => {
+    console.error(err);
+  });
