Overview ¶

Package h2c provides implementations of hashing functions that take arbitrary-length byte strings and output a point on an elliptic curve.

These methods follow the current work-in-progress standardization effort at IETF https://datatracker.ietf.org/doc/draft-irtf-cfrg-hash-to-curve.

Version: draft-irtf-cfrg-hash-to-curve-05

Types ¶

type HashToPoint ¶

type HashToPoint interface {
	// IsRandomOracle returns true if the output distribution is
	// indifferentiable from a random oracle.
	IsRandomOracle() bool
	// Hash returns a point on an elliptic curve given as input a string and a
	// domain separation tag.
	Hash(in, dst []byte) C.Point
	// GetCurve returns the destination elliptic curve.
	GetCurve() C.EllCurve
}

HashToPoint represents a complete and secure function for hashing strings to points.

type SuiteID ¶

type SuiteID string

SuiteID is the identifier of supported hash to curve suites.

func (SuiteID) Get ¶

func (id SuiteID) Get() (HashToPoint, error)

Get returns a HashToPoint based on the SuiteID, otherwise returns an error if the SuiteID is not supported or invalid.
