When finishing, bzip2 returns BZ_STREAM_END when it has produced all output.
If we end up calling the compression routine again (even with avail_in == 0),
bzip2 returns an error.

Fix a bug that affected bzip2 - the bzip2 library does not like
being called with avail_in == 0 and BZ_RUN, it returns PARAM_ERROR.
Just return in that case and ignore the call.

AEAD::output_length)
Fix a bug in CCM, GCM, and OCB decryption which caused `output_length(tag_size())`
to fail even though empty plaintexts are certainly defined for all three modes.

With sufficient squinting, Transform provided an abstract base
interface that covered both cipher modes and compression algorithms.
However it mapped on neither of them particularly well. In addition
this API had the same problem that has made me dislike the Pipe/Filter
API: given a Transform&, what does it do when you put bits in? Maybe
it encrypts. Maybe it compresses. It's a floor wax and a dessert topping!
Currently the Cipher_Mode interface is left mostly unchanged, with the
APIs previously on Transform just moved down the type hierarchy. I
think there are some definite improvements possible here, wrt handling
of in-place encryption, but left for a later commit.
The compression API is split into two types, Compression_Algorithm and
Decompression_Algorithm. Compression_Algorithm's start() call takes
the compression level, allowing varying compressions with a single
object. And flushing the compression state is moved to a bool param on
`Compression_Algorithm::update`. All the nonsense WRT compression
algorithms having zero length nonces, input granularity rules, etc
as a result of using the Transform interface goes away.

The tests previously had used 4 to 6 different schemes internally (the vec file
reader framework, Catch, the old InSiTo Boost.Test tests, the PK/BigInt tests
which escaped the rewrite in 1.11.7, plus a number of one-offs). Converge on a
design that works everywhere, and update all the things.
Fix also a few bugs found by the test changes: SHA-512-256 name incorrect,
OpenSSL RC4 name incorrect, signature of FFI function botan_pubkey_destroy
was wrong.

Fixes #146.

- Remove additional newlines in CHECK_MESSAGE call
- Remove redundant output of algo in aead_test()
Closes #115
|
|
Fix zlib decompression which was not ignoring Z_BUF_ERROR which is
harmless in this context as process is already checking avail_in
and avail_out after run returns.
Bump version to 1.11.17
