# getPublicKeyType

Gets the type of the public key used by the Encryptor Extension. This method returns a unique type identifier for the public key. It's important to ensure uniqueness when developing custom extensions.

### Usage

```ts
const publicKeyType = encryptorExtension.getPublicKeyType();
```

### Returns

`Promise<string>`

The unique public key type identifier. In this implementation, it returns `'BL_ENCRYPTOR_EC'`.

**Note:** If you're developing your own extension, make sure the returned type identifier is unique to your implementation. This ensures no conflicts arise with other extensions.
