Pieter Wuille 3bb9c44719 Rewrite ECDSA signature parsing code 
There are now 2 encoding formats supported: 64-byte "compact" and DER.
The latter is strict: the data has to be exact DER, though the values
inside don't need to be valid.

Pieter Wuille fa57f1bdf1 Use secp256k1_rand_int and secp256k1_rand_bits more 
Update the unit tests to make use of the new RNG functions.

Pieter Wuille 251b1a62d3 Improve testrand: add extra random functions 
This commit adds functions:
* secp256k1_rand_bits, which works like secp256k1_rand32, but consumes
  less randomness
* secp256k1_rand_int, which produces a uniform integer over any range
* secp256k1_rand_bytes_test, which works like secp256k1_rand256_test
  but for arbitrary byte array

ee2cb40 Add ARG_CHECKs to secp256k1_ec_pubkey_parse/secp256k1_ec_pubkey_serialize (Gregory Maxwell)

Gregory Maxwell 67f7da4087 Extensive interface and operations tests for secp256k1_ec_pubkey_parse. 
This also makes use of optional valgrind instrumentation if -DVALGRIND
 is set.

This also moves secp256k1.c above secp256k1.h in tests.c or otherwise
 we get non-null macros on the public functions which may defeat some
 of the VERIFY checks.

Gregory Maxwell ee2cb4007d Add ARG_CHECKs to secp256k1_ec_pubkey_parse/secp256k1_ec_pubkey_serialize 
This also makes secp256k1_ec_pubkey_parse's init of pubkey more unconditional.

Gregory Maxwell 213aa67397 Do not force benchmarks to be statically linked. 
Libtool will do the right thing and use whatever is available
 based on --enable-shared/--enable-static.

This also means that some of the things we build actually
 test the dynamic library.

118cd82 Use explicit symbol visibility. (Gregory Maxwell)

 2015-09-25 21:36:18 +02:00
Gregory Maxwell 118cd8210f Use explicit symbol visibility. 
The use of static makes this somewhat redundant currently, though if
 we later have multiple compilation units it will be needed.

This also sets the dllexport needed for shared libraries on win32.

Gregory Maxwell cfe0ed916a Fix miscellaneous style nits that irritate overactive static analysis. 
Also increase consistency with how overflow && zero is tested, and
 avoid some mixed declarations and code that GCC wasn't detecting.

Gregory Maxwell 2b199de888 Use the explicit NULL macro for pointer comparisons. 
This makes it more clear that a null check is intended. Avoiding the
 use of a pointer as a test condition alse increases the type-safety
 of the comparisons.

(This is also MISRA C 2012 rules 14.4 and 11.9)
