def scalarMultiplyBase(scalar: Array[Byte]): Array[Byte]

Multiply the Ed25519 base point by a scalar to derive the public key.

Multiply the Ed25519 base point by a scalar to derive the public key.

Given a 32-byte scalar k (little-endian), compute A = k * G where G is the Ed25519 base point.

Value parameters

scalar

32-byte scalar in little-endian format

Attributes

Returns

32-byte compressed public key point
