353c1bf0d7 Fix secp256k1_ge_set_table_gej_var parameter order 
Rearranged secp256k1_ge_set_table_gej_var parameters so length comes last (it modifies both *a and *zr).

c6191fded8 ecmult_const: unify endomorphism and non-endomorphism skew cases 
We now do a skew correction even without the endomorphism optimization,
which costs one additional group addition but unifies a lot of code.

47b9e78e07 Cast pointers through uintptr_t under JNI 
Fixes warnings of the form "warning: cast to pointer from integer of
different size" when building on 32 bit platforms. This is the same
approach used for pointer conversions in the openjdk sources.

f36f9c64bb bench_ecdh: fix call to secp256k1_context_create 2016-04-27 10:16:18 +00:00
Andrew Poelstra
bcc4881d3a Add some missing VERIFY_CHECK(ctx != NULL) for functions that use ARG_CHECK 
The `ARG_CHECK` macro requires that a variable called `ctx` exist and be
non-NULL. However, in several functions that do not use the context variable,
we simply ignore it with `(void)ctx`. Replace these with explicit checks for
non-NULLness to avoid invalid memory accesses.

26abce7 Adds 32 static test vectors for scalar mul, sqr, inv. (Gregory Maxwell)
 2015-10-31 02:21:35 +01:00
Gregory Maxwell
26abce75ea Adds 32 static test vectors for scalar mul, sqr, inv. 
These were generated by testing more than 10^12 random test vectors
 for coverage on instrumented (comparison operator outcomes) 32-bit
 and 64-bit code, plus additional edge condition requirements (e.g.
 inputs of 0, 1, -1) and then solving a minimum set cover problem.

The required responses were generated with Sage.

This significantly improves the lcov branch coverage report and
 makes the tests much more sensitive to mutation testing of the
 scalar code.

The challenges and responses are in the form of pairs of scalars:
  C1 * C2 == R1
  (C1 * C2) * (1 / C2) == C1
  C2 * (1 / C2) == 1
  C1 * C1 == R2
  C1^2    == R2

5b71a3f460 Better error case handling for pubkey_create & pubkey_serialize, more tests. 
Makes secp256k1_ec_pubkey_serialize set the length to zero on failure,
 also makes secp256k1_ec_pubkey_create set the pubkey to zeros when
 the key argument is NULL.

Also adds many additional ARGCHECK tests.
