Generates RSA-1024 key pairs via the Web Crypto API for display registration with Xibo CMS. The public key is sent during RegisterDisplay so the CMS can associate it with the display record.

API

`generateRsaKeyPair()`

Generate an RSA key pair (1024-bit, RSA-OAEP/SHA-256).

import { generateRsaKeyPair } from '@xiboplayer/crypto';

const { publicKeyPem, privateKeyPem } = await generateRsaKeyPair();
// publicKeyPem:  -----BEGIN PUBLIC KEY-----\nMIGf...
// privateKeyPem: -----BEGIN PRIVATE KEY-----\nMIIC...

Returns SPKI PEM (public) and PKCS8 PEM (private) strings compatible with PHP's openssl_get_publickey().

`isValidPemKey(pem)`

Validate that a string has correct PEM structure.

import { isValidPemKey } from '@xiboplayer/crypto';

isValidPemKey(publicKeyPem);  // true
isValidPemKey('garbage');     // false

Design

Zero runtime dependencies -- uses only the Web Crypto API (available in browsers, Electron, and Node.js 16+)
RSA-1024 matches the upstream .NET player key format
WebSocket XMR messages are plain JSON (no encryption needed) -- the key is only for CMS registration
Key rotation is triggered by the CMS via the XMR rekey command

Usage in the SDK

This package is used internally by @xiboplayer/utils (config) to generate and persist keys, and by @xiboplayer/xmds to send them during registration. You typically don't need to import it directly.
