This is an implementation of a Signature class that uses the IAIK PKCS#11 wrapper to access the
token. It only works with IAIKPKCS11PrivateKey and IAIKPKCS11PublicKey. This version uses the
CKM_ECDSA mechanism to create the signature; i.e. it creates the hash off-card. This class
generates the hash itself using a MessageDigest object. After hashing it sends the generated hash
to the token for signing.
