- * 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
- * that use the PKCS#11 engine by default, we must somehow avoid that regression
- * on machines without hardware acceleration. That's why switching to the
- * pkcs11_kernel library seems like a very good idea.
- *
- * The problem is that OpenSSL built with SunStudio is roughly 2x slower for
- * asymmetric operations (RSA/DSA/DH) than the soft token built with the same
- * compiler. That means that if we switched to pkcs11_kernel from the libpkcs11
- * library, we would have had a performance regression on machines without
- * hardware acceleration for asymmetric operations for all applications that use
- * the PKCS#11 engine. There is one such application - Apache web server since
- * it's shipped configured to use the PKCS#11 engine by default. Having said
- * that, we can't switch to the pkcs11_kernel library now and have to come with
- * a solution that, on non-accelerated machines, uses the OpenSSL native code
- * for all symmetric ciphers and digests while it uses the soft token for
- * asymmetric operations.
- *
- * This is the idea: dlopen() pkcs11_kernel directly and find out what
- * mechanisms are there. We don't care about duplications (more slots can
- * support the same mechanism), we just want to know what mechanisms can be
- * possibly supported in hardware on that particular machine. As said before,
- * pkcs11_kernel will show you hardware providers only.
- *
- * Then, we rely on the fact that since we use libpkcs11 library we will find
- * the metaslot. When we go through the metaslot's mechanisms for symmetric
- * ciphers and digests, we check that any found mechanism is in the table
- * created using the pkcs11_kernel library. So, as a result we have two arrays
- * of mechanisms that were advertised as supported in hardware which was the
- * goal of that whole exercise. Thus, we can use libpkcs11 but avoid soft token
- * code for symmetric ciphers and digests. See pk11_choose_slots() for more
- * information.
- *
- * This is Solaris specific code, if SOLARIS_HW_SLOT_SELECTION is not defined
