public final class NONEWithECDSASignature extends SignatureSpi
Use it like any other signature algorithm, but supply the hashed data
to the Signature.update(byte),
Signature.update(byte[]),
Signature.update(java.nio.ByteBuffer), and
Signature.update(byte[], int, int) methods instead of
the original data to be signed. You can call all of the update methods in any
combination. You have to ensure that the length of the hashed bytes in the
update methods fits the parameters of the curve.
If you are going to sign some yet not hashed data (respectively verify the corresponding signature), you can use the non-raw ECDSA implementations, which automatically hash the supplied data.
