Overview ¶
Package emparams contains emulation parameters for well known fields.
We define some well-known parameters in this package for compatibility and ease of use. When needing to use parameters not defined in this package it is sufficient to define a new type implementing [FieldParams]. For example, as:
type SmallField struct {}
func (SmallField) NbLimbs() uint { return 1 }
func (SmallField) BitsPerLimb() uint { return 11 }
func (SmallField) IsPrime() bool { return true }
func (SmallField) Modulus() *big.Int { return big.NewInt(1032) }
