Create a compact signature (65 bytes), which allows reconstructing the used public key.
The format is one header byte, followed by two times 32 bytes for the serialized r and s values. The header byte: 0x1B = first key with even y, 0x1C = first key with odd y, 0x1D = second key with even y, 0x1E = second key with odd y, add 0x04 for compressed keys.

Whether this private key is valid.
We check for correctness when modifying the key data, so fValid should always correspond to the actual state.
