setPrivateKey

fun setPrivateKey(privateKeyEntry: KeyStore.PrivateKeyEntry): SignerOptions.Builder
fun setPrivateKey(privateKey: PrivateKey): SignerOptions.Builder

Optionally setPrivateKey inserts Private key for signing PDF. Use this if you want PSPDFKit to do the document signing. Otherwise you need to overwrite the custom signing lambda in SigningManager.signDocument
