| | | | | | | | verify mode is not set, by default the Miller-Rabin bases are chosen from the small primes. Generally speaking these make good test bases. However if the prime to be generated is very small, we will choose a base which is out of range. If the i'th prime is too big to be a base, then just choose a random integer of the appropriate size instead.

* Devai Tamas pointed out on the mailing list that random_prime with bitslloyd2009-07-101-3/+3
| | | | | | set to 2, 3, or 4 was not returning a random prime due to reducing the rng output modulo 1 instead of mod 2 in choosing which prime of that size to return. Oops.

* CPU-specific engines are now only loaded if something depends on them,lloyd2009-07-079-11/+9
| | | | | | | | | | | | and all CPU-specific implementations now depend on the appropriate engine module. The most common problem before with this was that the SSE2 module was built, but the sole SSE2 code (SHA-1) was not (for instance, on an i686). This would cause a compile warning about the unused request object. Preventing unused engines from being built will also (very slightly) speed up the lookup process on most system.
* Fix a subtle bug in the /dev/*random reader. The maximum ms wait time waslloyd2009-07-021-2/+3
| | | | | | | | set to 1000 ms (scaling based on amount of data requested). At 1000 ms exactly, we would form a timeval of 0 seconds and 1000000 usecs (ie, 1 second). Linux was fine with this, but FreeBSD 7.0's select was returning EINVAL. Fix things to properly create the timeval so that everyone is happy.

* Change the makefile template language somewhat. Previously variableslloyd2009-07-017-121/+121
| | | | | | | | | | | | | | | | | had been denoted with @{var:NAME}, this has changed to %{NAME}. This is pretty much a wash for configure.pl but it makes it much easier to process the templates using Python's string.Template. The logic being the 'var:' prefix had been to support conditional statements in the templates (using an 'if:' prefix), but this functionality was not being used and support for it is removed from configure.pl in this revision. For a similiar reason, rename a number of template variables with hyphens in their name to use underscores instead. This is slightly more consistent anyway (since many variable names had already used _ instead of -) but more importantly makes them much easier to deal with using aforementioned Python template code. This should not result in any user-visible change (unless I messed up).
* Make the install_cmd_{data,exec} items in the build-data files quoted,lloyd2009-07-014-13/+6
| | | | | | | | | | | since they often contain spaces. This doesn't matter to configure.pl's hand-done regex 'parser', but it makes things more consistent and makes it possible to use the shlex parser included with python to parse all of the data files. Also remove the unused <arch> entry in darwin - this information had previously be removed from all the other files but I guess that one was missed.

* Use an input insensitive implementation of same_mem instead of memcmp.lloyd2009-06-221-1/+8
| | | | | | I don't know that having same_mem be sensitive to input would actually allow any form of timing attack in the current codebase, but it seemed like a prudent thing to do in any case.
* Improve handling of low-entropy situations in HMAC_RNG and Randpool.lloyd2009-06-212-8/+14
| | | | | | | | | | | When a reseed is attempted, up to poll_bits attempts will be made, running in order through the set of available sources. So for instance if poll_bits is set to the default 256, then up to 256 polls will be performed (some of which might not provide any entropy, of course) before stopping; of course if the accumulators goal is achived before that point, then the polling stops. This should greatly help to resolve the recent rash of PRNG unseeded problems some people have been having.

| | | | | | | | | | | | | | Add a comment that the limitation of the personalization string being a maximum of 64 characters is due to the implementation and not the specification (but it makes it easy to implement, and in this particular case 64 characters is probably fine). Add some tests for the personalization option, generated by the Skein reference implementation. Disable stripping whitespace in checks/misc.cpp:strip - it strips the personalization tag, which breaks the test, and isn't needed otherwise because the test files are well-formed.
