Function normalizeRootCAs

normalizeRootCAs(
input?: string | string[] | Buffer<ArrayBufferLike>,
): Buffer<ArrayBufferLike> | undefined
Loads user-supplied root certificates.

A Buffer contains the certificate data. A string contains a PEM file path. An array contains PEM file paths in concatenation order. The function returns the same Buffer instance when the input is a buffer.

Missing, empty, and unreadable files are ignored. If no path produces data, the function returns undefined; it does not throw.
Parameters
- Optionalinput: string | string[] | Buffer<ArrayBufferLike>
Returns Buffer<ArrayBufferLike> | undefined
Example
```
import { Buffer } from 'node:buffer';
import { normalizeRootCAs } from '@nebius/js-sdk/runtime/tls/system_certs';

const pem = Buffer.from('application-provided PEM data');
const roots = normalizeRootCAs(pem);
roots === pem; // true
```
