The order may be 1 bit larger than prime for some curves.
Handle this in calculation of maximum size of curve.
SP int _sp_mont_red(): ensure m->used is never 0 when doing default
implementaion.
Ed25519CheckPubKey/Ed448CheckPubKey: get the public key from certificate
in a new function, wc_CertGetPubKey, that uses less memory.
Set the ENCRYPT_BASE_BITS to minimal values when Curve448/Curve25519 are
the largest public key algorithms.
Move declaration of sp_ints until after checks of valid parameters.
In particular, whether used field of input/s are valid.
Pull implementations of algorithms out into separate functions as a
pattern to fix.
SP int should be able to calculate size of encoded number for a radix of
10 when mp_int has all digits used.
sp_radix_size declared a temporary mp_int of 1 greater than input. Don't
need it 1 greater. Stack declaration of maximum plus one caused address
sanitizer error.
Changed temporary mp_int to be same size as input mp_int.
fix for benign clang-analyzer-deadcode.DeadStores in aes.c:wc_AesFeedbackEncrypt();
fix for cppcheck:selfAssignment in chacha.c:wc_Chacha_wordtobyte().
- Add CONFIG_PTHREAD_IPC when using threads
- Add logging config suggestions
- test.c: fix undefined `ret` error
- Increase stack size for samples
- Ignore ASN_BEFORE_DATE_E in examples
- wc_port.h: add missing posix thread includes
- wc_port.h: move definitions to relevant section
- benchmark.c: fix missing `arc` and `argv` errors
- benchmark.c: fflush does not work on stdout in Zephyr
- Update z_fs_open implementation to support flags
CheckCertSignature
Free the dataASN before calling ConfirmSignature.
dataASN not needed at this point and ConfirmSignature uses lots of
memory.
DecodeCertInternal:
Free the dataASN before calling DecodeCertExtensions,
dataASN not needed at this point and DecodeCertExtensions uses more
memory.
ecc_verify_hash:
v doesn't need to be a new allocated variable - reuse w.
v is the modular reduction of x-ordinate to prime calculated at end.
New creation of mp_ints r and s to be minimal size must not be
re-initialized.
Changes to ASN.1 code to handle r and s being initialized and to not
initialize again.
Public API wc_ecc_is_point() needs to validate the parameters.
Ensure that the x and y are in range [0, p-1] and z is one (affine
ordinates).
Made the API a wrapper around existing calculation code.
When x-ordinate is a large negative, then it will spend large amounts of
time adding the prime to a large negative intermediate value.
