+ISC modified
+============
+
+The previous key naming scheme was kept for backward compatibility.
+
+The PKCS#11 engine exists in two flavors, crypto-accelerator and
+sign-only. The first one is from the Solaris patch and uses the
+PKCS#11 device for all crypto operations it supports. The second
+is a stripped down version which provides only the useful
+function (i.e., signature with a RSA private key in the device
+protected key store and key loading).
+
+As a hint PKCS#11 boards should use the crypto-accelerator flavor,
+external PKCS#11 devices the sign-only. SCA 6000 is an example
+of the first, AEP Keyper of the second.
+
+Note it is mandatory to set a pk11-flavor (and only one) in
+config/Configure.
+
+It is highly recommended to compile in (vs. as a DSO) the engine.
+The way to configure this is system dependent, on Unixes it is no-shared
+(and is in general the default), on WIN32 it is enable-static-engine
+(and still enable to build the OpenSSL libraries as DLLs).

+PKCS#11 engine support for OpenSSL 0.9.8l

+
+Overview
+========
+
+This patch containing code available in OpenSolaris adds support for PKCS#11
+engine into OpenSSL and implements PKCS#11 v2.20. It is to be applied against
+OpenSSL 0.9.8l source code distribution as shipped by OpenSSL.Org. Your system
+must provide PKCS#11 backend otherwise the patch is useless. You provide the
+PKCS#11 library name during the build configuration phase, see below.
+
+Patch can be applied like this:
+
+	# NOTE: use gtar if on Solaris
+	tar xfzv openssl-0.9.8l.tar.gz
+	# now download the patch to the current directory
+	# ...
+	cd openssl-0.9.8l
+	# NOTE: must use gpatch if on Solaris (is part of the system)
+	patch -p1 < path-to/pkcs11_engine-0.9.8l.patch.2009-11-19
+
+It is designed to support pure acceleration for RSA, DSA, DH and all the
+symetric ciphers and message digest algorithms that PKCS#11 and OpenSSL share
+except for missing support for patented algorithms MDC2, RC3, RC5 and IDEA.
+
+According to the PKCS#11 providers installed on your machine, it can support
+following mechanisms:
+
+	RSA, DSA, DH, RAND, DES-CBC, DES-EDE3-CBC, DES-ECB, DES-EDE3, RC4,
+	AES-128-CBC, AES-192-CBC, AES-256-CBC, AES-128-ECB, AES-192-ECB,
+	AES-256-ECB, AES-128-CTR, AES-192-CTR, AES-256-CTR, MD5, SHA1, SHA224,
+	SHA256, SHA384, SHA512
+
+Note that for AES counter mode the application must provide their own EVP
+functions since OpenSSL doesn't support counter mode through EVP yet. You may
+see OpenSSH source code (cipher.c) to get the idea how to do that. SunSSH is an
+example of code that uses the PKCS#11 engine and deals with the fork-safety
+problem (see engine.c and packet.c files if interested).
+
+You must provide the location of PKCS#11 library in your system to the
+configure script. You will be instructed to do that when you try to run the
+config script:
+
+	$ ./config 
+	Operating system: i86pc-whatever-solaris2
+	Configuring for solaris-x86-cc
+	You must set --pk11-libname for PKCS#11 library.
+	See README.pkcs11 for more information.
+
+Taking openCryptoki project on Linux AMD64 box as an example, you would run
+configure script like this:
+
+	./config --pk11-libname=/usr/lib64/pkcs11/PKCS11_API.so
+
+To check whether newly built openssl really supports PKCS#11 it's enough to run
+"apps/openssl engine" and look for "(pkcs11) PKCS #11 engine support" in the
+output. If you see no PKCS#11 engine support check that the built openssl binary
+and the PKCS#11 library from --pk11-libname don't conflict on 32/64 bits.
+
+The patch, during various phases of development, was tested on Solaris against
+PKCS#11 engine available from Solaris Cryptographic Framework (Solaris 10 and
+OpenSolaris) and also on Linux using PKCS#11 libraries from openCryptoki project
+(see openCryptoki website http://sourceforge.net/projects/opencryptoki for more
+information). Some Linux distributions even ship those libraries with the
+system. The patch should work on any system that is supported by OpenSSL itself
+and has functional PKCS#11 library.
+
+The patch contains "RSA Security Inc. PKCS #11 Cryptographic Token Interface
+(Cryptoki)" - files cryptoki.h, pkcs11.h, pkcs11f.h and pkcs11t.h which are
+copyrighted by RSA Security Inc., see pkcs11.h for more information.
+
+Other added/modified code in this patch is copyrighted by Sun Microsystems,
+Inc. and is released under the OpenSSL license (see LICENSE file for more
+information).

+FAQs
+====
+
+(1) my build failed on Linux distro with this error:
+
+../libcrypto.a(hw_pk11.o): In function `pk11_library_init':
+hw_pk11.c:(.text+0x20f5): undefined reference to `pthread_atfork'
+
+Answer:
+
+	- don't use "no-threads" when configuring
+	- if you didn't then OpenSSL failed to create a threaded library by
+	  default. You may manually edit Configure and try again. Look for the
+	  architecture that Configure printed, for example:
+
+Configured for linux-elf.
+
+	- then edit Configure, find string "linux-elf" (inluding the quotes),
+	  and add flags to support threads to the 4th column of the 2nd string.
+	  If you build with GCC then adding "-pthread" should be enough. With
+	  "linux-elf" as an example, you would add " -pthread" right after
+	  "-D_REENTRANT", like this:
+
+....-O3 -fomit-frame-pointer -Wall::-D_REENTRANT -pthread::-ldl:.....
+
+(2) I'm using MinGW/MSYS environment and get undeclared reference error for
+pthread_atfork() function when trying to build OpenSSL with the patch.
+
+Answer:
+
+	Sorry, pthread_atfork() is not implemented in the current pthread-win32
+	(as of Nov 2009). You can not use the patch there.
+
+
+Feedback
+========
+
+Please send feedback to security-discuss@opensolaris.org. The patch was
+created by Jan.Pechanec@Sun.COM from code available in OpenSolaris.
+
+Latest version should be always available on http://blogs.sun.com/janp.

+ * 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 excercise. 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
+ * the code won't be used.

+/* Before including this file (pkcs11.h) (or pkcs11t.h by
+ * itself), 6 platform-specific macros must be defined.  These
+ * macros are described below, and typical definitions for them
+ * are also given.  Be advised that these definitions can depend
+ * on both the platform and the compiler used (and possibly also
+ * on whether a Cryptoki library is linked statically or
+ * dynamically).
+ *
+ * In addition to defining these 6 macros, the packing convention
+ * for Cryptoki structures should be set.  The Cryptoki
+ * convention on packing is that structures should be 1-byte
+ * aligned.
+ *
+ * If you're using Microsoft Developer Studio 5.0 to produce
+ * Win32 stuff, this might be done by using the following
+ * preprocessor directive before including pkcs11.h or pkcs11t.h:
+ *
+ * #pragma pack(push, cryptoki, 1)
+ *
+ * and using the following preprocessor directive after including
+ * pkcs11.h or pkcs11t.h:
+ *
+ * #pragma pack(pop, cryptoki)
+ *
+ * If you're using an earlier version of Microsoft Developer
+ * Studio to produce Win16 stuff, this might be done by using
+ * the following preprocessor directive before including
+ * pkcs11.h or pkcs11t.h:
+ *
+ * #pragma pack(1)
+ *
+ * In a UNIX environment, you're on your own for this.  You might
+ * not need to do (or be able to do!) anything.
+ *
+ *
+ * Now for the macros:
+ *
+ *
+ * 1. CK_PTR: The indirection string for making a pointer to an
+ * object.  It can be used like this:
+ *
+ * typedef CK_BYTE CK_PTR CK_BYTE_PTR;
+ *
+ * If you're using Microsoft Developer Studio 5.0 to produce
+ * Win32 stuff, it might be defined by:
+ *
+ * #define CK_PTR *
+ *
+ * If you're using an earlier version of Microsoft Developer
+ * Studio to produce Win16 stuff, it might be defined by:
+ *
+ * #define CK_PTR far *
+ *
+ * In a typical UNIX environment, it might be defined by:
+ *
+ * #define CK_PTR *
+ *
+ *
+ * 2. CK_DEFINE_FUNCTION(returnType, name): A macro which makes
+ * an exportable Cryptoki library function definition out of a
+ * return type and a function name.  It should be used in the
+ * following fashion to define the exposed Cryptoki functions in
+ * a Cryptoki library:
+ *
+ * CK_DEFINE_FUNCTION(CK_RV, C_Initialize)(
+ *   CK_VOID_PTR pReserved
+ * )
+ * {
+ *   ...
+ * }
+ *
+ * If you're using Microsoft Developer Studio 5.0 to define a
+ * function in a Win32 Cryptoki .dll, it might be defined by:
+ *
+ * #define CK_DEFINE_FUNCTION(returnType, name) \
+ *   returnType __declspec(dllexport) name
+ *
+ * If you're using an earlier version of Microsoft Developer
+ * Studio to define a function in a Win16 Cryptoki .dll, it
+ * might be defined by:
+ *
+ * #define CK_DEFINE_FUNCTION(returnType, name) \
+ *   returnType __export _far _pascal name
+ *
+ * In a UNIX environment, it might be defined by:
+ *
+ * #define CK_DEFINE_FUNCTION(returnType, name) \
+ *   returnType name
+ *
+ *
+ * 3. CK_DECLARE_FUNCTION(returnType, name): A macro which makes
+ * an importable Cryptoki library function declaration out of a
+ * return type and a function name.  It should be used in the
+ * following fashion:
+ *
+ * extern CK_DECLARE_FUNCTION(CK_RV, C_Initialize)(
+ *   CK_VOID_PTR pReserved
+ * );
+ *
+ * If you're using Microsoft Developer Studio 5.0 to declare a
+ * function in a Win32 Cryptoki .dll, it might be defined by:
+ *
+ * #define CK_DECLARE_FUNCTION(returnType, name) \
+ *   returnType __declspec(dllimport) name
+ *
+ * If you're using an earlier version of Microsoft Developer
+ * Studio to declare a function in a Win16 Cryptoki .dll, it
+ * might be defined by:
+ *
+ * #define CK_DECLARE_FUNCTION(returnType, name) \
+ *   returnType __export _far _pascal name
+ *
+ * In a UNIX environment, it might be defined by:
+ *
+ * #define CK_DECLARE_FUNCTION(returnType, name) \
+ *   returnType name
+ *
+ *
+ * 4. CK_DECLARE_FUNCTION_POINTER(returnType, name): A macro
+ * which makes a Cryptoki API function pointer declaration or
+ * function pointer type declaration out of a return type and a
+ * function name.  It should be used in the following fashion:
+ *
+ * // Define funcPtr to be a pointer to a Cryptoki API function
+ * // taking arguments args and returning CK_RV.
+ * CK_DECLARE_FUNCTION_POINTER(CK_RV, funcPtr)(args);
+ *
+ * or
+ *
+ * // Define funcPtrType to be the type of a pointer to a
+ * // Cryptoki API function taking arguments args and returning
+ * // CK_RV, and then define funcPtr to be a variable of type
+ * // funcPtrType.
+ * typedef CK_DECLARE_FUNCTION_POINTER(CK_RV, funcPtrType)(args);
+ * funcPtrType funcPtr;
+ *
+ * If you're using Microsoft Developer Studio 5.0 to access
+ * functions in a Win32 Cryptoki .dll, in might be defined by:
+ *
+ * #define CK_DECLARE_FUNCTION_POINTER(returnType, name) \
+ *   returnType __declspec(dllimport) (* name)
+ *
+ * If you're using an earlier version of Microsoft Developer
+ * Studio to access functions in a Win16 Cryptoki .dll, it might
+ * be defined by:
+ *
+ * #define CK_DECLARE_FUNCTION_POINTER(returnType, name) \
+ *   returnType __export _far _pascal (* name)
+ *
+ * In a UNIX environment, it might be defined by:
+ *
+ * #define CK_DECLARE_FUNCTION_POINTER(returnType, name) \
+ *   returnType (* name)
+ *
+ *
+ * 5. CK_CALLBACK_FUNCTION(returnType, name): A macro which makes
+ * a function pointer type for an application callback out of
+ * a return type for the callback and a name for the callback.
+ * It should be used in the following fashion:
+ *
+ * CK_CALLBACK_FUNCTION(CK_RV, myCallback)(args);
+ *
+ * to declare a function pointer, myCallback, to a callback
+ * which takes arguments args and returns a CK_RV.  It can also
+ * be used like this:
+ *
+ * typedef CK_CALLBACK_FUNCTION(CK_RV, myCallbackType)(args);
+ * myCallbackType myCallback;
+ *
+ * If you're using Microsoft Developer Studio 5.0 to do Win32
+ * Cryptoki development, it might be defined by:
+ *
+ * #define CK_CALLBACK_FUNCTION(returnType, name) \
+ *   returnType (* name)
+ *
+ * If you're using an earlier version of Microsoft Developer
+ * Studio to do Win16 development, it might be defined by:
+ *
+ * #define CK_CALLBACK_FUNCTION(returnType, name) \
+ *   returnType _far _pascal (* name)
+ *
+ * In a UNIX environment, it might be defined by:
+ *
+ * #define CK_CALLBACK_FUNCTION(returnType, name) \
+ *   returnType (* name)
+ *
+ *
+ * 6. NULL_PTR: This macro is the value of a NULL pointer.
+ *
+ * In any ANSI/ISO C environment (and in many others as well),
+ * this should best be defined by
+ *
+ * #ifndef NULL_PTR
+ * #define NULL_PTR 0
