Pieter Wuille 9f56bdf5b9 Merge bench_schnorrsig into bench 2021-11-05 17:35:11 -04:00
Pieter Wuille 5324f8942d Make aux_rnd32==NULL behave identical to 0x0000..00. 
BIP340's default signing algorithm always requires an aux_rnd argument,
but permits using an all-zero one when no randomness is available.

Make secp256k1_schnorrsig_sign follow this even when aux_rnd32==NULL,
by treating the same as if an all-zero byte array was provided as
input.

Russell O'Connor 6815761cf5 Remove ecmult_context. 
These tables stored in this context are now statically available from the generated ecmult_static_pre_g.h file.

Tim Ruffing f698caaff6 Use unsigned char consistently for byte arrays 
C++ does not allow initialization with string literals but we do it in other
places and -fpermissive will convince g++ to compile.

Tim Ruffing 769528f307 Don't use string literals for char arrays without NUL termination 
unsigned char foo[4] = "abcd" is not valid C++ because the string
literal "abcd" does not fit into foo due to the terminating NUL
character. This is valid in C, it will just omit the NUL character.

Fixes #962.

Jonas Nick fdd06b7967 schnorrsig: add tests for sign_custom and varlen msg verification 2021-06-27 20:26:15 +00:00
Jonas Nick d8d806aaf3 schnorrsig: add extra parameter struct for sign_custom 
This simplifies the interface of sign_custom and allows adding more parameters
later in a backward compatible way.

Jonas Nick a0c3fc177f schnorrsig: allow signing and verification of variable length msgs 
Varlen message support for the default sign function comes from recommending
tagged_sha256. sign_custom on the other hand gets the ability to directly sign
message of any length. This also implies signing and verification support for
the empty message (NULL) with msglen 0.

Tests for variable lengths follow in a later commit.

Jonas Nick b6c0b72fb0 schnorrsig: remove noncefp args from sign; add sign_custom function 
This makes the default sign function easier to use while allowing more granular
control through sign_custom.

Tests for sign_custom follow in a later commit.

Jonas Nick 442cee5baf schnorrsig: add algolen argument to nonce_function_hardened

William Bright 3c90bdda95 change local lib headers to be relative for those pointing at "include/" dir 
added relative paths to header files imported from src directory

Gregory Maxwell 99e2d5be0d Avoids a missing brace warning in schnorrsig/tests_impl.h on old compilers. 
GCC 4.9.2, at least, emits "warning: missing braces around initializer"
 without this.

Russell O'Connor fb390c5299 Remove underscores from header defs. 
This makes them consistent with other files and avoids reserved identifiers.

Tim Ruffing e89278f211 Don't use reserved identifiers memczero and benchmark_verify_t 
As identified in #829 and #833. Fixes #829.

Since we touch this anyway, this commit additionally makes the
identifiers in the benchmark files a little bit more consistent.
