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
RSA_PKCS mechanism to create the signature. The application must provide a hash value as input.
Refer to the PKCS#11 v2.11 standard for details.
