43dbe1350a Forgot to add chacha.h to the build. 2017-04-06 19:51:45 +02:00
Dag-Erling Smørgrav
cfd3951ee1 Implement the ChaCha family of stream ciphers. 2017-04-06 19:51:45 +02:00
Dag-Erling Smørgrav
c2f4fa524f Second iteration of the cryb-cipher API. 
We now have separate encryption and decryption methods, and can process an arbitrary amount of plaintext or ciphertext per call, rounded down to the block size (if applicable).  For stream ciphers, we also have a keystream method which fills the provided buffer with an arbitrary amount of keystream (once again, rounded down if applicable).

3917a6dfd7 Annotate t_add_test() as printf()-like and fix the fallout. 2017-03-14 15:07:02 +01:00
Dag-Erling Smørgrav
52cf1f9d3c Rename t_verbose*() to t_printv*(). 
Not only is this a slightly more logical name, but it allows us to expose the verbose flag, previously private to cryb_t_main.c, as the equally logically named t_verbose.

cf46393d5e Remove an unused header and fix some naming nits. 2017-03-06 23:40:05 +01:00
Dag-Erling Smørgrav
d419d7388a Remove an unnecessary pointer from struct aes_ctx. 
The rk pointer in struct aes_ctx always pointed to the context's buffer and served no purpose whatsoever, but the compiler had no way of knowing that and could therefore not optimize away assignments to and from it.

Note that the removal of rk breaks the ABI, since it changes the size of struct aes_ctx, but we allow ourselves that because neither the API nor the ABI have been fixed yet.

Dag-Erling Smørgrav
856571a06d Implement a soft assert for unit tests. 
Unlike assert(3), which uses abort(3), this has no other side effects (before raising SIGABRT) than an fprintf() call.  The test framework will catch the SIGABRT, report that the test case failed, and proceed with the next case.

401465d8ea Move main() from libcryb-test to the test program. 
Instead of having libcryb-test provide main() and assume that the test program defines t_prepare() and t_cleanup(), have libcryb-test provide a t_main() function which the test program calls with pointers to its prepare and cleanup functions.

955cbc3013 Add t_malloc_snapshot() which writes a snapshot of the allocator state to 
a caller-provided buffer.  Use it to warn about leaks in each individual
test case.  Note that we can't fail a test case for leaking, because
individual test cases in a unit may modify shared state which is cleaned
up at the end of the series.

f82bbc1400 Catch up with OpenPAM's latest OATH changes: 
Add an oath_mode(3) function which translates from mode names to numbers.

 Consistently use UINT_MAX, not -1, to indicate an invalid response.

 Change the meaning of the window parameter to always indicate the number
 of codes to check *in addition* to the current code.  Note that for TOTP,
 the window goes in both directions; a window of 1 means to check the
 current code plus the previous and next.

6ed802ddf3 Consistently use #if HAVE_FOO instead of #ifdef HAVE_FOO. The reason is 
that AC_CHECK_DECLS([foo]), unlike AC_CHECK_FUNCS([foo]), will always
define HAVE_FOO, so #ifdef HAVE_FOO will always be true even if it is 0.
This commit finally fixes the [bl]e{32,64}{enc,dec} issue on Linux.

8ef2266a4b r103 was incomplete. It changed the checks in the configure script (and 
accidentally introduced a no-op line), but did not change the checks in
the header, so we ended up always using our own [bl]e{32,64}{enc,dec}.
