Support for Golang NaCl ciphertext output format about tink

[thaidn]

I found the implementation: https://github.com/golang/crypto/blob/master/nacl/box/box.go.

In NaClBoxCrypto we implemented NaCl's box using the HybridEncrypt and HybridDecrypt interface, but this is actually wrong because NaCl's box is authenticated public key encryption while our hybrid encryption doesn't provide authenticity (but only secrecy).

Thus in order to implement NaClBoxCrypto, first we'll need to add a new interface. We're working on that and I'll update this bug once it's done.

We also provide secret_box. I believe the only interoperability issue is we're using ciphertext || tag, but NaCl is using tag || ciphertext. I'll fix this issue.

Hi Ajibola,

Thanks for filing this request. Could you please point me to the NaCl impl. in Golang? Is it compatible with the original C/C++ NaCl?

Note that our NaClCrypto is @Alpha, and is going to be removed with a different interface.

thanks @thaidn for the follow up.

This has been open for 5 years -- I don't think we will soon get to this creating this primitive. I will hence close it.
