CBIORecv/Send are only assigned once.
IOCB_ReadCtx/WriteCtx only assigned once.
BuildMessage checks output and input wiht sizeOnly every call - state
machine doesn't cache these.
Renamed alias_tbl variables to something unique.
Other cppcheck fixes.
Also reworked pem_read_bio_key().
Passing in x=0 and y=0 meant to return ECC_INF_E.
Passing in x=0, y=not 0 or x=not 0, y=0 now checks whether the point is
valid and forces a return of BAD_FUNC_ARG when IS_POINT_E is returned
from check.
Allow Chachac20-Poly1305 to take an empty msg.
Allow AES-SIV to have an empty nonce.
Don't allow the length to be malleable. Must use the smallest number of
bytes to represent value.
ECDSA and DSA signature values are positive.
Add Sha512-224 and Sha512-256 OIDs.
ASN template - ensure the ECDSA/DSA signature uses all data.
Curve25519/Curve448 - WOLFSSL_ECDHX_SHARED_NOT_ZERO means shared secret
can't be 0.
Curve25519/Curve448 - check public value is less than order.
ECC - x or y may be zero but not both.
Ed25519/Ed448 - check S is less than order.
Ed448 - ge_p3_dbl can be simplified for ASM.
Prime check (integer.c/tfm.c/sp_int.c): Don't allow negative values and
make sure random candidate doesn't have bits higher than those in a set
when bits not a multiple of 8.
RSA: support Sha512-224 and Sha512-256.
RSA: Fix check for invalid in decryption. Affects plaintexts 256 bytes
and longer.
RSA: Don't allow base be larger than modulus.
RSA: Check small ciphertext (1 or 0) on decrypt when not using OAEP.
RSA: WOLFSSL_RSA_DECRYPT_TO_0_LEN allows decrypted value to be 0.
SP math all: fix div to handle large a and d when checking size of
remainder.
SP math all: set sign of result in sp_mod_2d()
Change Karatsuba implementations for x86_64.
Fix ECC code to better handle corner cases.
Add 'lower' versions of functions wehn an input is known to be less than m.
Add mont_add/dbl/tpl/sub for P384.
Change ECC point add to be cache-attack resistant.
Change mod_exp to be cache-attack resistant.
Need to right shift number down when hash is more than 521 bits.
Previously handled at a byte level and now at bit level.
Always return err from sp_*_ecc_mulmod_add_only_*().
When ECC add and double points are public and only have SP
implementation, check that the point ordinates are the right size.
Add support to ECIES for AES-256-CBC, AES-128-CTR, AES-256-CTR.
Added new API wc_ecc_ctx_set_algo() that sets the encryption, KDF and
MAC algorithms.
Cleanup formatting of ECIES code.
