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_DSA mechanism to create the signature; i.e. it calculates a raw DSA without hashing. The
applicaiton must already provide the SHA-1 hash as input data to this algorithm.
