So now because I'm just a single individual, bug fixes will probably lag behind upstream. All because Golang.org/x/crypto decided the OpenSSH variant was "too weird".

But, of course, not "weird" enough to [not support the *wire* protocol](https://go.googlesource.com/crypto/+/master/ssh/cipher.go#647) for SSH. Just the key encryption. Because of course. And not publicly exposed either. Because of course.

## Why is the name so ugly?

I couldn't think of a better one and I wanted something notably distinct from stdlib-x.

## Why don't you expose the rest of ChaCha20/Poly1305/ChaCha20-Poly1305? ## Why don't you expose the rest of ChaCha20/Poly1305/ChaCha20-Poly1305?

Because the code is minimally modified, the majority of the code's original license can be found via LICENSE.forked (of which the source can be found above).

Namely, some of these specific modifications are:

// Package poly1305 implements Poly1305 one-time message authentication code as
// specified in https://cr.yp.to/mac/poly1305-20050329.pdf.
//
// Poly1305 is a fast, one-time authentication function. It is infeasible for an
// attacker to generate an authenticator for a message without the key. However, a
// key must only be used for a single message. Authenticating two different
// messages with the same key allows an attacker to forge authenticators for other
// messages with the same key.
//
// Poly1305 was originally coupled with AES in order to make Poly1305-AES. AES was
// used with a fixed key in order to generate one-time keys from an nonce.
// However, in this package AES isn't used and the one-time key is specified
// directly.
//
// Deprecated: Poly1305 as implemented by this package is a cryptographic
// building block that is not safe for general purpose use.
// For encryption, use the full ChaCha20-Poly1305 construction implemented by
// golang.org/x/crypto/chacha20poly1305. For authentication, use a general
// purpose MAC such as HMAC implemented by crypto/hmac.
