+[PFX or PKCS12](https://en.wikipedia.org/wiki/PKCS_12) encoded private key and certificate chain. Using `options.https.pfx` is an alternative to providing `options.https.key` and `options.https.certificate` individually. A PFX is usually encrypted, and if it is, `options.https.passphrase` will be used to decrypt it.
+
+Multiple PFX's can be be provided as an array of unencrypted buffers or an array of objects like:
+
+```ts
+{
+	buffer: string | Buffer,
+	passphrase?: string
+}
+```
+
+This object form can only occur in an array. If the provided buffers are encrypted, `object.passphrase` can be used to decrypt them. If `object.passphrase` is not provided, `options.https.passphrase` will be used for decryption.
