-+ * It would be great if we could use pkcs11_kernel directly since this library
-+ * offers hardware slots only. That's the easiest way to achieve the situation
-+ * where we use the hardware accelerators when present and OpenSSL native code
-+ * otherwise. That presumes the fact that OpenSSL native code is faster than the
-+ * code in the soft token. It's a logical assumption - Crypto Framework has some
-+ * inherent overhead so going there for the software implementation of a
-+ * mechanism should be logically slower in contrast to the OpenSSL native code,
-+ * presuming that both implementations are of similar speed. For example, the
-+ * soft token for AES is roughly three times slower than OpenSSL for 64 byte
-+ * blocks and still 20% slower for 8KB blocks. So, if we want to ship products
