[Bug]: Missing LICENSE file for pemutil/ssh.go's "BSD-style license"

[jas4711]

Steps to Reproduce

Hi. I'm packaging this for Debian, and we are going through license statements. The pemutil/ssh.go file begins with:

// Copyright 2012 The Go Authors. All rights reserved.
// Use of this source code is governed by a BSD-style
// license that can be found in the LICENSE file.

But I cannot find this file in this package. Could you add it, or at least qualify which license applies to this work? "BSD-style" is not universially unambigious, and having clear licensing matters to Debian.

Your Environment

Debian

Expected Behavior

Appropriate LICENSE file included

Actual Behavior

Appropriate LICENSE file missing

Reading the code has a link to:

https://github.com/golang/crypto/blob/master/ssh/keys.go

Which uses this BSD-license:

https://github.com/golang/crypto/blob/master/LICENSE

I'm going to assume this is the intended "BSD-style" license, but clarifying this file would be good.

Hi @jas4711,

I added the header and the comment because I got the definition of the structure openSSHPrivateKey and the magic header from x/crypto/ssh. I did that because I needed to detect whether a key was password-protected.

In fact, I also moved those structs in x/crypto/ssh from anonymous structs to named ones. I did that because I implemented ssh.MarshalPrivateKey and ssh.MarshalPrivateKeyWithPassphrase from my own implementation of pemutil.SerializeOpenSSHPrivateKey.

I think it is safe to remove or ignore that header. I'm raising this question to confirm that I can remove the comment.

Hi! Was any code copied? I think that is the main question if the old copyright/license has to be retained or not.
