func (Field) ReducedElementFromBytes

func (f Field) ReducedElementFromBytes(bytes []byte) *Element

ReducedElementFromBytes initializes a new field element from big-endian bytes and reduces it by the modulus of the field.

WARNING: If this is used with cryptographic constructions which rely on a uniform distribution of values, this may introduce a bias to the value of the returned field element. This happens when the integer range of the provided bytes is not an integer multiple of the field order.

Assume we are working in field which a modulus of 3 and the range of the uniform random bytes we provide as input is 5. Thus, the set of field elements is {0, 1, 2} and the set of integer values for the input bytes is: {0, 1, 2, 3, 4}. What is the distribution of the output values produced by this function?

ReducedElementFromBytes(0) => 0
ReducedElementFromBytes(1) => 1
ReducedElementFromBytes(2) => 2
ReducedElementFromBytes(3) => 0
ReducedElementFromBytes(4) => 1

For a value space V and random value v, a uniform distribution is defined as P[V = v] = 1/|V| where |V| is to the order of the field. Using the results from above, we see that P[v = 0] = 2/5, P[v = 1] = 2/5, and P[v = 2] = 1/5. For a uniform distribution we would expect these to each be equal to 1/3. As they do not, this does not return uniform output for that example.

To see why this is okay if the range is a multiple of the field order, change the input range to 6 and notice that now each output has a probability of 2/6 = 1/3, and the output is uniform.

func (s *ScalarEd25519) SetBytes(input []byte) (Scalar, error)

SetBytes takes input a 32-byte long array and returns a ed25519 scalar. The input must be 32-byte long and must be a reduced bytes.

func (*ScalarEd25519) SetBytesCanonical

func (s *ScalarEd25519) SetBytesCanonical(bytes []byte) (Scalar, error)

SetBytesCanonical uses SetCanonicalBytes of fillipo.io/edwards25519. https://github.com/FiloSottile/edwards25519/blob/v1.0.0-rc.1/scalar.go#L98 This function takes an input x and sets s = x, where x is a 32-byte little-endian encoding of s, then it returns the corresponding ed25519 scalar. If the input is not a canonical encoding of s, it returns nil and an error.

func (*ScalarEd25519) SetBytesClamping

func (s *ScalarEd25519) SetBytesClamping(bytes []byte) (Scalar, error)

SetBytesClamping uses SetBytesWithClamping of fillipo.io/edwards25519- https://github.com/FiloSottile/edwards25519/blob/v1.0.0-rc.1/scalar.go#L135 which applies the buffer pruning described in RFC 8032, Section 5.1.5 (also known as clamping) and sets bytes to the result. The input must be 32-byte long, and it is not modified. If bytes is not of the right length, SetBytesWithClamping returns nil and an error, and the receiver is unchanged.

func (*ScalarEd25519) SetBytesWide

func (s *ScalarEd25519) SetBytesWide(bytes []byte) (Scalar, error)

SetBytesWide takes input a 64-byte long byte array, reduce it and return an ed25519 scalar. It uses SetUniformBytes of fillipo.io/edwards25519 - https://github.com/FiloSottile/edwards25519/blob/v1.0.0-rc.1/scalar.go#L85 If bytes is not of the right length, it returns nil and an error
