public final class SHA224WithPlainECDSASignature extends SignatureSpi
SEQUENCE as done by [2]. If the hash
length is larger than the domain parameter length the hash is not truncated
like in [2]; rather it is reduced modulo the order of the base point.
Note that instances of this class can only be initialized with keys of size greater than 224 bits.
