* Restrict dyn_load to platforms where it might theoretically work:lloyd2010-07-281-0/+9
| | | | | | | | Linux, Solaris, and the BSDs. Solaris and BSD are untested, but it seems like they should work. Using libdl on Solaris is seemingly only required in Solaris 9 and earlier, but 10 has a stub library so it should work there as well.
* Remove redundant setting for adding libdl link on Linux in dyn_engine;lloyd2010-07-281-4/+0

* There was an interesting bug affecting dynamically loaded engines.lloyd2010-07-272-4/+14
| | | | | | | | | | | | | | | | | | | | | | | The library initializer runs some self tests; this brings objects for a few select types (AES, SHA-1, etc) into the caches. Later on, when we add a dynamic engine, the engines aren't requeried because the cache has hits. So, for instance an dlopen'ed engine that provided AES-128 would not actually be used unless you called on the algo factory with a provider of "blah" - even using set_preferred_provider would have no effect, because that's just a request. Add a new function to Algorithm_Cache, clear_cache, which just deletes everything that is currently loaded (this is 90% of the destructor). Then call this on each cache in Algorithm_Factory when a new Engine is loaded. In normal use, this should be very fast because on init the engines are loaded one after another so clear_cache() won't do much work at all, but it ensures that if you load an engine later on in runtime it will always be found. It does have the downside that the app will then requery each Engine for each new algo after this point, but I think typically loading a dynamic engine will happen very early on so this won't be too much of a hassle. (And even if it happens in the middle of execution, everything still works, it just means some overhead the first time you ask for algo X).
* In Algorithm_Factory, delete the Engines after deleting the cacheslloyd2010-07-271-2/+2
| | | | | | | | rather than before. Otherwise, we run into a problem with dynamically loaded engines: the engine will be deleted (and thus, the external library unloaded), before calling the destructors on any objects which may have been cached, so we jump to a now invalid address instead of the destructor code.
* Add a new utility class Dynamically_Loaded_Library which wraps aroundlloyd2010-07-277-0/+308
| | | | | | | | | | the system dynamic linker (if any). Currently it only supports dlopen, and is only enabled on Linux. It will almost certainly work on BSDs and Solaris as well, though, and should be easy to extend to support Win32-style dynamic loading. Also add a new engine, Dynamically_Loaded_Engine, which loads up a new Engine object from a shared library/DLL.

As far as I can tell, the only still active release of any Linux/BSD distro that uses 2.4 is RHEL5. The beta of RHEL6 has 2.6, and it seems likely that RHEL6 will be out before 1.10.0.

* Rename S2K to PBKDF, because that is by far the most common name - S2Klloyd2010-07-0916-118/+108
| | | | | | | | | | | | | really is only used by OpenPGP, and largely it was named S2K here because the OpenPGP S2K was implemented years before the ones in PKCS #5. We have a typedef of PBKDF to S2K, and an inlined get_s2k that calls get_pbkdf for source compatability. There doesn't seem to be any reason to have a forward for the renamed s2k.h header - to actually use a PBKDF, you'd have to either include lookup.h and call get_s2k / get_pbkdf, or else include an algorithm-specific header and use it directly. In either case, including s2k.h is neither necessary nor sufficient.

* Argh: SecureVector's constructor needs to behave differentlylloyd2010-07-071-2/+14
| | | | | | | | | | | | | | depending on if INITIAL_LEN is non-zero. Normal semantics are the vector will change size based on whatever it is constructed with, but that's bad in cases like SecureVector<byte, 4> val(buffer, 3); which in the past would be a 4 valued thing with 3 elements set and one zero trailing. (This construct showed up in base64 and possibly elsewhere). If INITIAL_LEN is set, use copy instead so the length does not change. C++0x cannot come soon enough.
