Overview ¶
Package algopts provides shareable options for modifying algebraic operations.
This package is separate to avoid cyclic imports and sharing the structures between interface definition, implementation getters and actual implementations.

Functions ¶
func NewConfig ¶
func NewConfig(opts ...AlgebraOption) (*algebraCfg, error)
NewConfig applies all given options and returns a configuration to be used.
Types ¶
type AlgebraOption ¶
type AlgebraOption func(*algebraCfg) error
AlgebraOption allows modifying algebraic operation behaviour.
func WithCompleteArithmetic ¶
func WithCompleteArithmetic() AlgebraOption
WithCompleteArithmetic forces the use of safe addition formulas for scalar multiplication.
func WithFoldingScalarMul ¶
func WithFoldingScalarMul() AlgebraOption
WithFoldingScalarMul can be used when calling MultiScalarMul. By using this option we assume that the scalars are `1, scalar, scalar^2, ...`. We use the first element as the scalar to be used as a folding coefficients. By using this option we avoid one scalar multiplication and do not need to compute the powers of the folding coefficient.
func WithNbScalarBits ¶
func WithNbScalarBits(bits int) AlgebraOption
WithNbScalarBits defines the number bits when doing scalar multiplication. May be used when it is known that only bits least significant bits are non-zero. Reduces the cost for scalar multiplication. If not set then full width of scalars used.
