Functions

func EncodeToCurve

func EncodeToCurve(input, dst []byte) *nistec.P384Point

EncodeToCurve implements encode-to-curve mapping to P384 of input with dst. The DST must not be empty or nil, and is recommended to be longer than 16 bytes.

func HashToCurve

func HashToCurve(input, dst []byte) *nistec.P384Point

HashToCurve implements hash-to-curve mapping to P384 of input with dst. The DST must not be empty or nil, and is recommended to be longer than 16 bytes.

func HashToScalar

func HashToScalar(input, dst []byte) *big.Int

HashToScalar returns a safe mapping of the arbitrary input to a scalar for the prime-order group of P384. The DST must not be empty or nil, and is recommended to be longer than 16 bytes.
