Equivalent of Sodium's crypto_box_seal(..) / crypto_box_seal_open(..)?

[getify]

I see this quote on the README:

Nacl / Libsodium popularized term "secretbox", a simple black-box authenticated encryption. Secretbox is just xsalsa20-poly1305. We provide the alias and corresponding seal / open methods.

A couple of questions:

1. Sodium uses the term "secretbox" (crypto_secretbox_easy(..) and crypto_secretbox_easy_open(..)) for its symmetric authenticated encryption (same key for encryption/decryption). Further, they use the term "box" (crypto_box_easy(..) and crypto_box_easy_open(..)) for their asymmetric authenticated encryption (by generating an ephemeral keypair).

   But they use "sealedbox" (crypto_seal(..) and crypto_seal_open(..)) terminology for its un-authenticated (anonymous) asymmetric encryption/decryption.

   Do you support (have aliases for) all three of these: "secretbox", "box", and "sealedbox"? Or only some of them?

2. Where specifically on the noble-ciphers API are these various "seal / open method" aliases located? I couldn't find them.

---

My desired goal is to do the "sealedbox" equivalent with Noble, from this Sodium-using code:

let encBuffer = sodium.crypto_seal(msgBuffer, x25519pk, ivBuffer);
let msgBuffer_2 = sodium.crypto_seal_open(encBuffer, x25519sk, ivBuffer);

I'm trying to figure out if these aliases already exist, or if the pieces are there in Noble (Ciphers, etc) to do the equivalent operations, specifically where values would be interchangeable between a Sodium-using implementation and a Noble-using implementation.

Any thoughts/tips/guidance are appreciated.

secretbox is available natively

crypto_box, others etc (combining x25519) are available in noble-sodium wrapper around noble cryptography: https://github.com/serenity-kit/noble-sodium
