This is a feature request for adding an AVX2 implementation of Argon2. Currently there is a generic / pure Go and an amd64 SSE4.1 implementation.
An AVX2 implementation can improve performance about ~30 %. The AVX2 implementation requires Go 1.10 because of some instructions which are not supported by the assembler in earlier releases.
