method ECDH.prototype.setPrivateKey
Usage in Deno
```typescript import { ECDH } from "node:node__crypto.d.ts"; ```
ECDH.prototype.setPrivateKey(privateKey: ArrayBufferView): void
Sets the EC Diffie-Hellman private key.
If `encoding` is provided, `privateKey` is expected
to be a string; otherwise `privateKey` is expected to be a `Buffer`, `TypedArray`, or `DataView`.
If `privateKey` is not valid for the curve specified when the `ECDH` object was
created, an error is thrown. Upon setting the private key, the associated
public point (key) is also generated and set in the `ECDH` object.
