* NR_Verification_Operation::verify_mr would return false if the inputlloyd2012-05-181-1/+1
| | | | | | | | | | was not the right size for a signature (following DSA). This would silently convert to an empty vector which we would treat as a valid message on the return. However the EMSA checks will always fail so not a huge problem. While checking this out I noticed that an empty value for EMSA4 would result in us reading memory we didn't own.

* KeyPair::check_key's behavior of throwing an exception upon failure waslloyd2010-03-211-15/+1
| | | | | | | | | | | | | | not useful; in all cases, we immediately caught it and then returned false. Modify as follows: - Create the pubkey objects inside the checking code, so calling code doesn't need to do it. - Return true/false for pass/fail Also add consistency checking for ECDSA keys
* DSA and NR require certain parameters (which depend on the randomlylloyd2010-03-091-9/+12
| | | | | | choosen nonce) not be 0. Previously it would just check and throw an exception if this was the case. Change to generate a new nonce and retry if this happens.
* Deconstify PK_Ops. It's quite reasonable that some op will want tolloyd2010-03-092-4/+4
| | | | | | | | | | | | | precompute only as needed, or will want to access some other expensive resource or etc. Change how the secret for generating blinding is done in cases where a PRNG isn't available. Use the operations public op to hide the secret, for instance the seed for a DH blinding variable is 2^x mod p. Make use of being able to mutate internal structures in the RW signer, since that does have access to a PRNG, so use it to initialize the blinder on first call to sign().
* Modify pubkey classes to take names instead of object pointers.lloyd2010-03-081-4/+5
| | | | | Remove use of look_pk from the source and examples, instead instantiate classes directly.

| | | | | PK_Decrypting_Key, PK_Signing_Key, PK_Verifying_with_MR_Key, and PK_Verifying_wo_MR_Key.

* Add signature generation operation classes. Remove sign() fromlloyd2010-03-052-3/+57
| | | | | | PK_Signing_Key, though for the moment the class remains because there are a few pieces of code that use it to detect if signatures are supported, or for passing to functions in look_pk

* Add similar decoding constructors to the private keyslloyd2010-03-041-1/+7

* Add a new constructor to each public key algorithm (only the publiclloyd2010-03-041-1/+6
| | | | | | | keys so far, private keys not changed) that takes an AlgorithmIdentifier and a MemoryRegion<byte>&. This performs the X.509 decoding. It is not possible anymore to create uninitialized PK objects.
* Add missing BOTAN_DLL exports.lloyd2009-12-161-1/+1

* Remove the 'realname' attribute on all modules and cc/cpu/os info files.lloyd2009-10-291-2/+0
| | | | | Pretty much useless and unused, except for listing the module names in build.h and the short versions totally suffice for that.
* Add a script that reads the output of print_deps.py and rewriteslloyd2009-07-151-2/+2
| | | | | | the info.txt files with the right module dependencies. Apply it across the codebase.
* Move the contents of pubkey/pubkey (which was kind of a catch-all tolloyd2009-07-151-1/+0
| | | | | | | just toplevel pubkey). This was a convention I realized made sense sometime on when I was first doing the modularization changes. Move pkcs8.* and x509_key.* to pk_codecs
* engine.h had copies of some declarations from pk_engine.h that had notlloyd2009-05-131-1/+1
| | | | | | been removed when that portion of the code was split off. Remove the duplicated code from engine.h and update some code in pubkey that still relied on the declarations in engine.h instead of pk_engine.h
* Thomas Moschny passed along a request from the Fedora packagers which camelloyd2009-03-306-90/+102
| | | | | | | | | | | | | | | up during the Fedora submission review, that each source file include some text about the license. One handy Perl script later and each file now has the line Distributed under the terms of the Botan license after the copyright notices. While I was in there modifying every file anyway, I also stripped out the remainder of the block comments (lots of astericks before and after the text); this is stylistic thing I picked up when I was first learning C++ but in retrospect it is not a good style as the structure makes it harder to modify comments (with the result that comments become fewer, shorter and are less likely to be updated, which are not good things).
* Remove pk_lookup - half of it (look_pk.{cpp,h}) depended on libstate directly,lloyd2008-11-111-1/+0

| | | | | | | with the aid of macro hackery, at the moment). Change DH feature macro to BOTAN_HAS_DIFFIE_HELLMAN Change NR feature macro to BOTAN_HAS_NYBERG_RUEPPEL
* Move last pieces of algorithm-specific code from general 'pubkey' modulelloyd2008-10-014-2/+133

| | | | | | | | | | it builds if it is disabled. Current deficiency: due to #if defined(BLAH) in the engine code, Botan will not be binary compat across different configurations b/c the vtable will change size. Move some source from core/ to core/libstate where it belonged (engine stuff)
