Add a define WOLFSSL_CHECK_MEM_ZERO to turn on code that checks that
memory that must be zeroized before going out of use is zero.
Everytime sensitive data is put into a allocated buffer or stack buffer;
the address, its length and a name is stored to be checked later.
Where the stack buffer is about to go out of use, a call is added to
check that the required parts are zero.
wc_MemZero_Add() adds an address with length and name to a table of
addressed to be checked later.
wc_MemZero_Check() checks that the memory associated with the address is
zeroized where required.
mp_memzero_add() adds mp_int's data pointer with length and name to
table.
mp_memzero_check() checks that the data pointer is zeroized where
required.
Freeing memory will check the address. The length was prepended on
allocation.
Realloction was changed for WOLFSSL_CHECK_MEM_ZERO to perform an
allocate, check, copy, free.
The test for certificate extensions requires both the test certs option
and the certificate generation option to run. The certs for the test are
generated by wolfCrypt. This disables the extensions test if
certificate generation is disabled.
* Sniffer: Remove old restrictions for max strength, encrypt-then-mac and forcing openssl-extra.
* Fix bound warning with strncpy in sniffer.c.
* Fix for async DH issue.
* Fix for SP math all not initializing raw big int.
* Fix for array bounds warning with "-O3" on SetEccPublicKey.
* Fix a sniffer async edge case with TLS v1.2 static RSA and extended master.
* Improved the sniffer test script detection of features.
* Disable ECC custom curve test with Intel QuickAssist.
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()
Added a test for the TLSv1.3 KDF to the wolfcrypt test. It uses 6
different test cases from the CAVP tests. A set of 8 session keys are
generated using multiple exporters.
