Returns a signature of the data, using SignNR (Nyberg-Rueppel),
provided random data and hash algorithm SHA-256.
On entry, rand should be a random number as byte array with bit length
this.BitLength + 4. E.g. for curve 1 is BitLength is 160 bit,
thus random data length must be 164 bit or 21 bytes.
Random bytes are used in msb first order.
