Types

type API

type API struct {
	// contains filtered or unexported fields
}

An API used for operations related to [32]vars.Bit.

func NewAPI

func NewAPI(api builder.API) API

Creates a new bits32.API.

func (*API) Add

func (a *API) Add(in ...[32]vars.Bool) [32]vars.Bool

Computes the binary sum of two 32 bit arrays. Equivalently, think of this as addition modulo 2^32.

func (*API) And

func (a *API) And(in ...[32]vars.Bool) [32]vars.Bool

Computes the and of 32 bit arrays.

func (*API) Not

func (a *API) Not(i1 [32]vars.Bool) [32]vars.Bool

Computes the not of a 32 bit array.

func (*API) Rotate

func (a *API) Rotate(i1 [32]vars.Bool, offset int) [32]vars.Bool

Rotates a 32-length bit array by a given offset to the right.

func (*API) Shr

func (a *API) Shr(i1 [32]vars.Bool, offset int) [32]vars.Bool

Shifts a 32-length bit array by a given offset to the right.

func (*API) Xor

func (a *API) Xor(in ...[32]vars.Bool) [32]vars.Bool

Computes the xor of 32 bit arrays.
