Types ¶
type Client ¶
type Client struct {
Identifier
// contains filtered or unexported fields
}
Client implements the OPRF client and holds its state.
type Identifier ¶ added in v0.9.1
type Identifier string
Identifier of the OPRF compatible cipher suite to be used.
const ( // Ristretto255Sha512 is the OPRF cipher suite of the Ristretto255 group and SHA-512. Ristretto255Sha512 Identifier = "ristretto255-SHA512" // P256Sha256 is the OPRF cipher suite of the NIST P-256 group and SHA-256. P256Sha256 Identifier = "P256-SHA256" // P384Sha384 is the OPRF cipher suite of the NIST P-384 group and SHA-384. P384Sha384 Identifier = "P384-SHA384" // P521Sha512 is the OPRF cipher suite of the NIST P-512 group and SHA-512. P521Sha512 Identifier = "P521-SHA512" )
func IDFromGroup ¶ added in v0.9.1
func IDFromGroup(g group.Group) Identifier
IDFromGroup returns the OPRF identifier corresponding to the input group.
func (Identifier) Available ¶ added in v0.9.1
func (i Identifier) Available() bool
Available returns whether the Identifier has been registered of not.
func (Identifier) Client ¶ added in v0.9.1
func (i Identifier) Client() *Client
Client returns an OPRF client.
func (Identifier) DeriveKey ¶ added in v0.9.1
func (i Identifier) DeriveKey(seed, info []byte) *group.Scalar
DeriveKey returns a scalar mapped from the input.
func (Identifier) Evaluate ¶ added in v0.9.1
func (i Identifier) Evaluate(privateKey *group.Scalar, blindedElement *group.Element) *group.Element
Evaluate evaluates the blinded input with the given key.
func (Identifier) Group ¶ added in v0.9.1
func (i Identifier) Group() group.Group
Group returns the Group identifier for the cipher suite.
