Exported Values

var Basepoint []byte Basepoint is the canonical Curve25519 generator.
const PointSize = 32 PointSize is the size of the point input to X25519.
func ScalarBaseMult(dst, scalar *[32]byte) ScalarBaseMult sets dst to the product scalar * base where base is the standard generator. It is recommended to use the X25519 function with Basepoint instead, as copying into fixed size arrays can lead to unexpected bugs.
func ScalarMult(dst, scalar, point *[32]byte) ScalarMult sets dst to the product scalar * point. Deprecated: when provided a low-order point, ScalarMult will set dst to all zeroes, irrespective of the scalar. Instead, use the X25519 function, which will return an error.
const ScalarSize = 32 ScalarSize is the size of the scalar input to X25519.
func X25519(scalar, point []byte) ([]byte, error) X25519 returns the result of the scalar multiplication (scalar * point), according to RFC 7748, Section 5. scalar, point and the return value are slices of 32 bytes. scalar can be generated at random, for example with crypto/rand. point should be either Basepoint or the output of another X25519 call. If point is Basepoint (but not if it's a different slice with the same contents) a precomputed implementation might be used for performance.
