+### `generateKeyPair()`
+
+Generates an Ed25519 public/private key pair for use with other methods in this package that accept `CryptoKey` objects.
+
+```ts
+import { generateKeyPair } from '@solana/keys';
+
+const { privateKey, publicKey } = await generateKeyPair();

+
+### `getBase58EncodedAddressFromPublicKey()`
+
+Given a public `CryptoKey`, this method will return its associated `Base58EncodedAddress`.

+
+const address = await getBase58EncodedAddressFromPublicKey(publicKey);
+```

+### `signBytes()`
+
+Given a private `CryptoKey` and a `Uint8Array` of bytes, this method will return the 64-byte Ed25519 signature of that data as a `Uint8Array`.
+
+```ts
+import { signBytes } from '@solana/keys';
+
+const data = new Uint8Array([1, 2, 3]);
+const signature = await signBytes(privateKey, data);
+```
+
+### `verifySignature()`
+
+Given a public `CryptoKey`, an `Ed25519Signature`, and a `Uint8Array` of bytes, this method will return `true` if the signature was produced by signing the bytes using the private key associated with the public key, and `false` otherwise.
