Tobias Brunner f7a73fe0f7 hashers: Change names of SHA2 hash algorithms 
Keep the lower case names as they are as we use them internally (parsing
and e.g. in OpenSSL as identifier).

Tobias Brunner 54f8d09261 auth-cfg: Store signature schemes as signature_params_t objects 
Due to circular references the hasher_from_signature_scheme() helper
does not take a signature_params_t object.

Tobias Brunner 024b979522 certificate: Return signature scheme and parameters from issued_by() method 
This also required some include restructuring (avoid including library.h
in headers) to avoid unresolvable circular dependencies.

Tobias Brunner 0ae19f0ced configure: Fix gperf length parameter determination 
gperf is not actually a build dependency as the generated files are
shipped in the tarball.  So the type depends on the gperf version on
the host that ran gperf and created the tarball, which might not be
the same as that on the actual build host, and gperf might not even
be installed there, leaving the type undetermined.

Fixes: e0e4322973 ("configure: Detect type of length parameter for gperf generated function")

Tobias Brunner e0e4322973 configure: Detect type of length parameter for gperf generated function 
Since 3.1 gperf uses size_t for the length parameter instead of an
unsigned int.

Tobias Brunner 525cc46cab Change interface for enumerator_create_filter() callback 
This avoids the unportable 5 pointer hack, but requires enumerating in
the callback.

Tobias Brunner f6083d350c iv-gen: Use NULL IV generator for NULL encryption 
We don't need an IV for NULL encryption, so we wouldn't technically need
an IV generator.  But some of the code currently relies on an IV
generator to be present.  So we don't have to change that code and
handle IV size == 0 specially we use the new NULL IV generator, which
handles this transparently to the existing code.

Before 3c81cb6fc3 ("aead: Create AEAD using traditional transforms
with an explicit IV generator") iv_gen_rand_t was used for NULL
encryption, which would work too but this way it's clearer.

Martin Willi b756eea4f4 ivgen: Allow reusing the same message ID twice in sequential IV gen 
We use the message ID and fragment number as IV generator. As IKEv2 uses
distinct message ID counters for actively and passively initiated exchanges,
each IV would be used twice. As we explicitly reject such message IDs since
d0ed1079, original-responder initiated exchanges fail with counter mode ciphers.

This commit separates IV space in two halves for sequential IVs, and
automatically assigns once reused sequence numbers to the second half.

Fixes #980.

Martin Willi ef31254d34 iv-gen: Fail getting shorter IV values than the used counter size 
While no algorithm actually uses such short IVs, we add a check here to ensure
we won't return just the lower bits of the counter.
 2015-06-01 09:42:10 +02:00
Martin Willi d0ed107910 iv-gen: Ensure external sequential IVs are actually sequential 
We allow gaps in IVs, but ensure that an IV is never used more than once.

Martin Willi 3a5106caea crypto-tester: Use the plugin feature key size to benchmark crypters/aeads 
We previously didn't pass the key size during algorithm registration, but this
resulted in benchmarking with the "default" key size the crypter uses when
passing 0 as key size.

Martin Willi 3c81cb6fc3 aead: Create AEAD using traditional transforms with an explicit IV generator 
Real AEADs directly provide a suitable IV generator, but traditional crypters
do not. For some (stream) ciphers, we should use sequential IVs, for which
we pass an appropriate generator to the AEAD wrapper.
