Export an RSA private key as DER-encoded PKCS#1 RSAPrivateKey.

PKCS#1 is the legacy RSA-only format. For algorithm-agnostic export, use exportPkcs8Der.

function exportPkcs1Der(
	privateKey: CryptoKey,
): Promise<Uint8Array>

Parameters

• privateKey: CryptoKey

Throws

• Error — If the key is not an RSA key
