* When creating a PBKDF2, first check if the argument name is a knownlloyd2010-08-211-2/+6
| | | | | | | | | | | | | MAC. If it is, use it as the PRF. Otherwise assume it is a hash function and use it with HMAC. Instead of instantiating the HMAC directly, go through the algorithm factory. Add a test using PBKDF2 with CMAC(Blowfish); Blowfish mainly because it supports arbitrarily large keys, and also the required 4 KiB of sbox tables actually would make it fairly useful in that it would make cracking using hardware or GPUs rather expensive. Have not confirmed this vector against any other implementation because I don't know of any other implementation of PBKDF2 that supports MACs other than HMAC.

* Move the functions that directly manipulate the global state singletonlloyd2010-08-066-67/+165
| | | | | | | | | | | into global_state.{h,cpp}. Move all of the functions into a new namespace Global_State_Management, though exposing global_state() into the Botan namespace for compatability. Also add new functions global_state_exists and set_global_state_unless_set which may be helpful in certain tricky initialization scenarios (eg when an application using botan also uses a library which may or may not itself use botan).

* Rename S2K to PBKDF, because that is by far the most common name - S2Klloyd2010-07-093-12/+22
| | | | | | | | | | | | | 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.

* There are some nasty API problems that are caused by having to pass alloyd2010-03-194-8/+235
| | | | | | | | | | | | | | | | | | | | | | | | PRNG everywhere. The removal of the global PRNG was generated by a desire to remove the global library state entirely. However the real point of this was to remove the use of globally visible _mutable_ state; of the mutable state, the PRNG is probably the least important, and the most useful to share. And it seems unlikely that thread contention would be a major issue in the PRNG. Add back a global PRNG to Library_State. Use lazy initialization, so apps that don't ever use a PRNG don't need a seeding step. Then have AutoSeeded_RNG call that global PRNG. Offer once again RandomNumberGenerator& Library_State::global_rng(); which returns a reference to the global PRNG. This RNG object serializes access to itself with a mutex. Remove the hack known as Blinding::choose_nonce, replace with using the global PRNG to choose a blinding nonce

* This checkin represents a pretty major change in how PK operations arelloyd2010-03-042-27/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | performed. Up until now, each key object (eg DSA_PublicKey or ECDH_PrivateKey) had two jobs: contain the key material, and know how to perform any operations on that key. However because of a desire to support alternative implementations (GNU MP, hardware, whatever), there was a notion of operations, with the key objects containing an op that they got via engine rather than actually implementing the underlying algorithms directly. Now, represent the operation as an abstract interface (typically mapping a byte string to a byte string), and pass a plain Public_Key& or Private_Key& to the engine. The engine does any checks it wants (eg based on name, typeid, key sizes, etc), and either returns nothing (I'll pass) or a pointer to a new operation that represents signatures or encryption or what-have-you using that key. This means that plain key objects no longer contain operations. This is a major break with the traditional interface. On the other hand, using these 'bare' operations without padding, KDFs, etc is 99% of the time a bad idea anyway (and if you really need them, there are options so you get the bare op but via the pubkey.h interfaces). Currently this change is only implemented for DH and ECDH (ie, key agreement algorithms). Additionally the optional engines (gnump and openssl) have not been updated. I'll probably wait to touch those until after I can change them all in one go for all algos.

| | | | | | | | | | | scheme, which is supposed to use the IEEE 1363-style concatenation format, was identified with the X9.62 OIDs, which are documented to use the DER sequence format. Switch the BSI ones to use the OIDs allocated for this purpose by BSI, and add the X9.62 ECDSA/SHA-1 OID since that was missing. Correct an ECDSA test that assumed the cert was identified with the BSI OID, even though in fact the cert in question uses an X9.62-style format.

Turns out OpenSSL does have PEM encoding of EC params (openssl ecparam), and uses "EC PARAMETERS". As good as anything else, and allows interop, so change to use that.
