Reduce cryptography usage in --cfg=fuzzing
...
This reduces the usage of real cryptography in --cfg=fuzzing,
specifically replacing the secret->public key derivation with a
simple copy and ECDH with XOR of the public and private parts
(plus a stream of 1s to make a test pass that expected non-0
output).
It leaves secret tweak addition/multiplication as-is.
It also changes the context creation to over-allocate and store
the context flags at the end of the context buffer, allowing us
to easily test context flags in each function.
While it would be nice to have something fancier (eg XOR-based),
its not immediately obvious how to accomplish this, and better to
fix the issues I have than spend too much time on it.
Fixes #271 .

Do not test secret->public derivation or pk validity in fuzzing cfg
...
In the next commit the secret->public key derivation in fuzzing cfg
is changed to be simpler, as well as the validity rules of public
keys relaxed.
This adds a new test to ensure random keys can be added, not just
the hard-coded keys test that exists today.

Manually test that panicking from C will abort the process
...
Panicking from C is not UB in newer rust versions and will reliably
trigger an abort (without unwinding). In older rust versions, it is
technically UB but empirically it seems to "just work" (and what should
it realistically do except crashing, which is what we intent).
Since there's potentially no unwinding, we can't test this behavior
using [should_panic]. This PR will instead check the libtest output
explicitly in our CI tests.
Fixes #228 .

have to disable the `test_panic_raw_ctx` test.

libsecp256k1 really only barely uses libc at all, and in practice,

libc call. Thus, if we provide simple stub headers, things seem to
work with wasm-pack just fine.

adding a tweak to a private key and multiplying by the generator

Update for breaking changes in underlying rustc.
...
This should be a major version number since I changed public constants
in the ffi module. I'm not doing so as the invariant "will the constants
be meaningful to the underlying library" has not changed.
In general this library's version numbers do not map well to the
underlying library, which is as-yet not versioned at all, so users
need to always be running "the lastest" rust-secp256k1 anyway, and
semantic versioning can't really be used meaninfully. So this is a
bit of a judgement call.

[BREAKING CHANGE] Make PK::from_secret_key() return a Result; change from_ffi functions to From impls
...
If you try to call PublicKey::from_secret() key with an incapable context it will
now return an error. Before it would pass through to the underlying library which
would terminate the process, something we strive to never expose.
Also change the from_ffi functions on various types to impl's of From to be more
Rustic. We cannot change the from_slice functions because they have error returns.
Also add a Secp256k1::without_caps() function which creates a capability-less
context. I find myself using this in so many places downstream that it seems
appropriate.

[API BREAK] expose ability to create contexts without verify or signing caps
...
There are a lot of cases in rust-bitcoin where we need a `Secp256k1`
which doesn't need any signing or verification capabilities, only
checking the validity of various objects. We can get away with a bare
context (i.e. no precomputation) which can be cheaply created on demand,
avoiding the need to pass around references to Secp256k1 objects everywhere.
API break because the following functions can now fail (given an insufficiently
capable context) and therefore now return a Result:
Secp256k1::generate_keypair
Secp256k1::sign
Secp256k1::sign_compact
2015-04-13 22:15:52 -05:00

[API BREAK] Remove Rng from Secp256k1 and associated code
...
The Rng was only used for key generation, and for BIP32 users not even then;
thus hauling around a Rng is a waste of space in addition to causing a
massive amount of syntactic noise. For example rust-bitcoin almost always
uses `()` as the Rng; having `Secp256k1` default to a `Secp256k1<Fortuna>`
then means even more syntactic noise, rather than less.
Now key generation functions take a Rng as a parameter, and the rest can
forget about having a Rng. This also means that the Secp256k1 context
never needs a mutable reference and can be easily put into an Arc if so
desired.
2015-04-12 15:54:22 -05:00
83823379e4
[minor API BREAK] Add unit tests to cover all error cases
...
This comes with a couple bugfixes and the following API changes:
- Secp256k1::sign and ::sign_compact no longer return Result;
it is impossible to trigger their failure modes with safe
code since the `Message` and `SecretKey` types validate when
they are created.
- constants::MAX_COMPACT_SIGNATURE_SIZE loses the MAX_; signatures
are always constant size
- the Debug output for everything is now hex-encoded rather than
being a list of base-10 ints. It's just easier to read this way.
kcov v26 now reports 100% test coverage; however, this does not
guarantee that test coverage is actually complete. Patches are
always welcome for improved unit tests.
