We compute a variety of non-selfadjoint operator algebras that depend on the choice of the covariance relation, along with the smallest $\\ca$-algebra they generate, namely the $\\ca$-envelope. We then relate each occurrence of the $\\ca$-envelope to (a full corner of) an appropriate twisted crossed product.
