method DiffieHellman.prototype.setPrivateKey
Usage in Deno
```typescript import { DiffieHellman } from "node:node__crypto.d.ts"; ```
DiffieHellman.prototype.setPrivateKey(privateKey: ArrayBufferView): void
Sets the Diffie-Hellman private key. If the `encoding` argument is provided,`privateKey` is expected
to be a string. If no `encoding` is provided, `privateKey` is expected
to be a `Buffer`, `TypedArray`, or `DataView`.
This function does not automatically compute the associated public key. Either `diffieHellman.setPublicKey()` or `diffieHellman.generateKeys()` can be
used to manually provide the public key or to automatically derive it.
