| | | | | | | | | | | | | | finalized. Move header to passhash9.h and rename the functions to be passhash9 specific ({generator,check}_passhash9) Add an algorithm identifer field. Currently only id 0 is defined, for HMAC(SHA-1), but this opens up for using HMAC(SHA-512) or HMAC(SHA-3) or CMAC(Blowfish) or whatever in the future if necessary. Increase the salt size to 96 bits and the PRF output size to 192 bits. Document in api.tex

* Prefix passhash with "$9$" in a manner similar with otherlloyd2010-02-023-16/+31
| | | | | | | | | | | | | | | | password hashing schemes. Increase salt size to 80 bits. Research shows that virtually no other PBKDF2 implementations support anything but SHA-1; for ease of implementation elsehwere switch back from SHA-512 to SHA-1. Should be mostly harmless; it limits total entropy of the password to a maximum of 160 bits, but this is unlikely anyway. Use two bytes to specify the work factor for future-proofing. Add a test.
* Password hashing is a pretty useful service, really. Move the guts oflloyd2010-02-013-0/+125
| | | | | | | | the passhash example to the library. Support variable work factors; default work factor of 10 takes about half a second to do one password on my Core2. Switch to using SHA-512 instead of SHA-1 in PBKDF2. To keep the output evenly sized for base64 purposes, reduce PBKDF2 output size by one byte (to 112 bits).
* Modify the S2K interface. Instead of being stateful in terms of the saltlloyd2010-02-011-6/+6
| | | | | | | | | | | and iteration count, force it to be passed to each call to derive_key. So remove current_salt, set_iterations, new_random_salt, and change_salt functions from S2K interface. Update examples and test application to match. While I was in there, change the passhash example to use 64 bit salts and 128 bit PBKDF2 outputs.
* Clean up exceptions. Remove some unused ones like Config_Error. Makelloyd2010-01-051-1/+1
| | | | | | | Invalid_Argument just a typedef for std::invalid_argument. Make Botan::Exception a typedef for std::runtime_error. Make Memory_Exhaustion a public exception, and use it in other places where memory allocations can fail.
* Avoid MSVC warning 4800 about implicit conversion from T to bool. Mostlylloyd2009-12-231-1/+1

* Un-internal loadstor.h (and its header deps, rotate.h andlloyd2009-12-214-4/+4
| | | | | | | | | | | | | | bswap.h); too many external apps rely on loadstor.h existing. Define 64-bit generic bswap in terms of 32-bit bswap, since it's not much slower if 32-bit is also generic, and much faster if it's not. This may be quite helpful on 32-bit x86 in particular. Change formulation of generic 32-bit bswap. It may be faster or slower depending on the CPU, especially the latency and throuput of rotate instructions, but should be faster on an ideally superscalar processor with rotate instructions (ie, what I expect future CPUs to look more like).
* Add missing BOTAN_DLL exports.lloyd2009-12-163-14/+14
| | | | Move most of the engine headers to internal
* Make many more headers internal-only.lloyd2009-12-164-5/+5
| | | | | | | | | | | | | Fixes for the amalgamation generator for internal headers. Remove BOTAN_DLL exporting macros from all internal-only headers; the classes/functions there don't need to be exported, and avoiding the PIC/GOT indirection can be a big win. Add missing BOTAN_DLLs where necessary, mostly gfpmath and cvc For GCC, use -fvisibility=hidden and set BOTAN_DLL to the visibility __attribute__ to export those classes/functions.

* Add missing header guards to package.h and botan.hlloyd2009-12-021-0/+5
| | | | | Change serp_simd_sbox.h's header guard to use the leading BOTAN_ prefix for proper macro namespacing.
* Move most code that relies heavily on Filters into src/filters.lloyd2009-11-1712-0/+953
Remove support for (unused) modset settings. Move tss, fpe, cryptobox, and aont to new dir constructs
