}
COSEKey represents a key decoded from COSE format.
type COSEKeyType ¶ added in v0.18.1
type COSEKeyType int
COSEKeyType is a number identifying a key type
const ( KeyTypeOKP COSEKeyType = 1 KeyTypeEC2 COSEKeyType = 2 KeyTypeRSA COSEKeyType = 3 )
enum values for COSEKeyType type
type Error ¶ added in v0.18.1
type Error struct {
// contains filtered or unexported fields
}
Error represents an error in a WebAuthn relying party operation
type Group ¶
type Group interface {
GetRandomElement() *big.Int
Mul(*big.Int, *big.Int) *big.Int
Exp(*big.Int, *big.Int) *big.Int
Inv(*big.Int) *big.Int
}
Group interface is used to enable the usage of different groups in some schemes. For example when we have a homomorphism f between two groups and we are proving that we know an f-preimage of an element - meaning that for a given v we know u such that f(u) = v. Note that this is an interface for modular arithmetic groups. For elliptic curve groups at the moment there is no need for an interface.
