* Big, invasive but mostly automated change, with a further attempt atlloyd2010-09-0771-157/+165
| | | | | | | | | | | | | | harmonising MemoryRegion with std::vector: The MemoryRegion::clear() function would zeroise the buffer, but keep the memory allocated and the size unchanged. This is very different from STL's clear(), which is basically the equivalent to what is called destroy() in MemoryRegion. So to be able to replace MemoryRegion with a std::vector, we have to rename destroy() to clear() and we have to expose the current functionality of clear() in some other way, since vector doesn't support this operation. Do so by adding a global function named zeroise() which takes a MemoryRegion which is zeroed. Remove clear() to ensure all callers are updated.
* Realization while thinking about the recently added truncate: in a STLlloyd2010-09-076-51/+39
| | | | | | | | | | | | | | | | | | container like vector, truncate is simply resize, but what MemoryRegion called resize will zap the entire contents, and then what was resize was called grow_to. This is really problematic in terms of the goal of replacing MemoryRegion with a vector with a custom allocator. In this checkin: - Remove MemoryRegion::grow_to and MemoryRegion::truncate - Change the semantics of MemoryRegion::resize to change the size while keeping any current contents intact (up to the new size), zero initializing any new values. Unrelated, just noticed the lack while I was in there, add a version of CryptoBox::decrypt taking a std::string for the input.

| | | | | | | | | | | | | | | | | | really didn't need to. The ones in symkey and big_code were actually calling accessor functions to do the encoding themselves without a Pipe (should have definitely recognized that as a code smell). These versions have changed semantically with this checkin - previously they would completely ignore bad inputs, but now invalid inputs are rejected. For instance, you cannot say SymmetricKey key("Only some of this is hex, most of it isn't"); And expect to get a valid key formed by filtering out the non-hex characters and then decoding it. This is almost certainly a good thing. Also fix include in Botan.xs

* | For passhash9, add another interface that allows the caller to specifylloyd2010-08-222-14/+35
|/ | | | | | | | | | | which PRF they want to use. The old interface just calls this new version with alg_id set to 0 which is HMAC(SHA-1), which was previously the only supported PRF. Assign new codepoints for HMAC(SHA-256) and CMAC(Blowfish) to allow their use with passhash9. Have the generate+check tests run a test for each supported PRF.
* 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.
* Turns out OpenSSL's implementation of PBKDF2 allows empty passphrases,lloyd2010-08-212-6/+11
| | | | | | | | | | | | | | | | | so for compatability with keys that were encrypted with an empty passphrase we probably want to support it as well. In PBKDF2, don't reject empty passphrases out of hand; simply call set_key and if the underlying MAC cannot use the key, throw an informative exception. This will also be more helpful in the case that someone tries using another MAC (say, CMAC) with a block cipher that only supports keys of specific sizes. In HMAC, allow zero-length keys. This is not really optimal in the sense of allowing the user to do something dumb, but a 1 byte key would be pretty dumb as well and we already allowed that.

* In the first round of AES, use a 256 element table and do thelloyd2010-08-181-9/+28
| | | | | | | | | | | | | rotations in the code. This reduces the number of cache lines potentially accessed in the first round from 64 to 16 (assuming 64 byte cache lines). On average, about 10 cache lines will actually be accessed, assuming a uniform distribution of the inputs, so there definitely is still a timing channel here, just a somewhat smaller one. I experimented with using the 256 element table for all rounds but it reduced performance significantly and I'm not sure if the benefit is worth the cost or not.

* The changelog for 1.9.4 claimed that the default PKCS #8 encryptionlloyd2010-08-131-1/+1
| | | | | | | | | | algorithm had changed to AES-256. This was wrong, it actually changed to AES-128. However in retrospect AES-256 is probably a reasonable move (in particular for the 4 extra rounds; the related key attacks possible against AES-256 are probably not viable since we generate the key using PBKDF2), so update the 1.9.4 changelog to correctly indicate the change made in that release, and also modify PKCS #8 to actually use AES-256.
