//go:build !go1.21

// This package use build tags to select between github.com/minio/sha256-simd
// for go1.20 and bellow and crypto/sha256 for go1.21 and above.
// This is used because a fast SHANI implementation of sha256 is only avaiable
// in the std for go1.21 and above. See https://go.dev/issue/50543.
// TODO: Once go1.22 releases remove this package and replace all uses
// with crypto/sha256 because the two supported version of go will have the fast
// implementation.
