Checks that the argument, as little-endian integer, is a reduced non-zero element of the scalar field.
Checks that the argument, as little-endian integer, is a reduced element of the base field.
Converts endianness by reversing the input value.
Generates the shared secret according to the ECDH standard.
Calculates the public key from a given private key for use by either ECDSA or ECDH.
Decodes a point according to the three encodings above.
Compressed encoding: “02 || Px” if Py is even and “03 || Px” if Py is odd.
Hybrid encoding: “06 || Px || Py” if Py is even and “07 || Px || Py” if Py is odd (a pretty useless encoding).
Uncompressed encoding: “04 || Px || Py”.
Raw scalar multiplication by the base point of the elliptic curve.
Raw scalar multiplication by any point on the elliptic curve.
Creates an ECDSA signature, using a two-step procedure.
Second step of creating an ECDSA signature, using a two-step procedure.
Verifies an ECDSA signature.
