v0.5.0
What's New
- Implemented RSA PKCS#1v1.5 & RSASSA-PSS signature verification functions for SHA-384
- [Example] Added actions
rsasha34&rsapsssha34
What's Changed
- Eliminated potential RSA signature malleability when
s >= n - Fixed initializing
ec_curve_fpconstants - Fixed
ec_fixed_bigintfor unaligned bit sizes - Optimized passing of
std::spanandstd::string_viewobjects to functions, potentially eliminating pointer indirection and aliasing - Rename
assert_rsa_sha1_asserttoassert_rsa_sha1 - Rename
buffer_base::alloctobuffer_base::resize - Renamed word size function to
bitsize_to_wordsize - Updated test gen. scripts

v0.4.0
What's New
- Implemented SHA-384 hash function
- Added
ec_point_fp_jacobiwhich represents EC point in Jacobi coordinates.
Utilizing Jacobi coordinates yields up to 25% greater efficiency in EC point addition, and up to 32% greater efficiency when elliptic curve coefficients are a = 0 or a = -3 (secp256k1 and secp256r1, respectively).
What's Changed
- Optimized point multiplication in Homogeneous coordinates and function
ec_mul_add_fastto use NAF method (non-adjacent form representation of signed integer) for EC point-scalar multiplication.
This optimization resulted in an additional up to 10% increase in efficiency for EC point multiplication. - Optimized EC point doubling for the cases where elliptic curve coefficient a = 0 or a = -3 (secp256k1 and secp256r1, respectively).
- Optimized signature verification times of
ecdsa_verifyfunction by usingec_point_fp_jacobias point types for scalar-point multiplication & addition - Fixed bugs

- Fixed broken implementation of SHA3-512
- Added
fixed_bytesalias forstd::array<byte_t, N> - Added compile time
from_hexwhich returnsack::fixed_bytes - Refactored
from_hexfunction to allow odd length hex string - Updated copyright year
- Other bug fixes
