CustomPublicKey is similar to rsa.PrivateKey, containing information needed for a private key used in the partially blind signature protocol.
type BigPrivateKey struct {
Pk *BigPublicKey
D *big.Int
P *big.Int
Q *big.Int
}
func NewBigPrivateKey(sk *rsa.PrivateKey) *BigPrivateKey
NewBigPrivateKey creates a BigPrivateKey from a rsa.PrivateKey.
BigPublicKey is the same as an rsa.PublicKey struct, except the public key is represented as a big integer as opposed to an int. For the partially blind scheme, this is required since the public key will typically be any value in the RSA group.
type BigPublicKey struct {
N *big.Int
E *big.Int
}
func NewBigPublicKey(pk *rsa.PublicKey) *BigPublicKey
NewBigPublicKey creates a BigPublicKey from a rsa.PublicKey.
func (pub *BigPublicKey) Marshal() []byte
Marshal encodes the public key exponent (e).
func (pub *BigPublicKey) Size() int
Size returns the size of the public key.
