wc_RsaEncryptSize(): assumed a key size of 2048 when using hardware key.
Added callback to do lookup and implemented for PKCS#11.
If lookup not supported then assumes 2048 bits.
Minimize use of stack.
Make very large stack allocations dynamic memory allocations unless
WOLFSSL_SP_NO_MALLOC.
ProcessBufferTryDecode() split up into a function for each type.
ProcessBufferTryDecodeRsa() decodes the data and gets key size rather
than having or allocating an RsaKey.
Added wc_RsaPrivateKeyValidate() that only validates the encoding is an
RSA key and returns the key size in bytes.
For SP int, only create sp_ints of required size in RSA and ECC
implementation. For WOLFSSL_SMALL_STACK, memory is allocated to have
just enough bytes and size is set to maximum supported. Otherwise,
relies on dynamic stack variables.
For ECC, MAX_ECC_BITS_USE used when dynamic stack variables not
supported. Significantly reduces memory usage when RSA/DH is also built.
Add macros to sp_int.h, tfm.h and integer.h to support declaring,
allocating, initializing and freeing mp_ints.
For integer.h, mp_int is always static as size is no more than 32 bytes.
For tfm.h, WOLFSSL_SMALL_STACK has a full mp_int allocated, otherwise
the full mp_int is put on the stack.
For sp_int.h with new macros, dynamically allocate sp_int to minimal
size when WOLFSSL_SMALL_STACK, or when dynamic stack variables, declare
them to be of minimal size or otherwise declare with a fixed max.
Added mp_bitsused(), for all implementations, to get the number of bits
available based on used. Included for RSA to get the size of the
modulus.
SP int now always uses dynamic stack variables if possible rather than
for builds with WOLFSSL_SP_SMALL.
Moved code out into separate functions so that stack allocations don't
happen when not going down code path.
Fix checking of negative with unsigned variables.
Check digestSz for 0 in wc_SSH_KDF() so that no possibility of dividing
by zero.
Change XMEMCPY to XMEMSET in renesas_sce_util.c.
Fix test.c to free prvTmp and pubTmp on read error.
Remove unused variables.
XFREE checks for NULL so don't check before call.
Move variable declarations to reduce scope.
ForceZero the client and server secret regardless of whether TLS 1.3 as
it may change but have been copied in.
ForceZero the input buffer in wolfSSL_Clear() when encryption was on.
Changed wc_PRF_TLS to only check the parts of data used.
Changed where scatch is added for checking in wc_AesCtrEncrypt.
Change wc_MakeRsaKey to memset p, q, tmp1, tmp2 and tmp3 to all zeros so
that MemZero check works. Memset not needed otherwise.
Changes for new compiler - thinks uninitialized.
HAVE_ECH only used by TLS 1.3 add protection around all code.
ssl->options.onlyPskDheKe only available when HAVE_SUPPORTED_CURVES.
CleanupClientTickets() defined when HAVE_SUPPORTED_CURVES.
TLSX_KeyShare_DeriveSecret only defined when HAVE_SUPPORTED_CURVES.
DecodeResponseData - initialize variable single.
New OpenSSL compatibility BN code requires mp_read_radix - turn on in
integer.c, sp_int.c when OPENSSL_EXTRA defined.
rsa.c:_CheckProbablePrime - make sure tmp1 and tmp2 are initialized
before error handling jumps to freeing them.
test_remove_hs_message uses 1024-bit DH key which is not supported when
using SP math with SP.
* Fixed `PEM_BUFSIZE` macro redefined when building with coexist.
* Updated the `user_settings_all.h` and `user_settings_wolfboot_keytools.h` to include latest options.
* Improved API unit test error case checking where `TEST_RES_CHECK` is not used.
* Changed `TEST_SKIPPED` to unique value.
* Added CI tests for enable-all, small stack, and user setting templates.
* add Versal specific glue
The same structure of an "XSecure client" is used throughout the API's,
therefor define it once and re-use in all clients.
* integrate Versal AES-GCM engine
* integrate Versal SHA3-384 engine
* add versal support to tests
- There's no intermediate-hash API for Versal.
* add specific test with large AAD
Test only with `n*16 byte` wide chunks of AAD, so it gets processed in the
hardware engine.
* add specific test with misaligned AES-GCM arguments
* integrate Versal RSA engine
* disable failing RSA test-case when Xilinx Crypto is enabled
* introduce define `WOLFSSL_XILINX_CRYPT_VERSAL`
* integrate Versal TRNG engine
* allow using Versal TRNG w/o wolfcrypt DRBG
Versal TRNG already provides a HRNG mode which does the same as the
wolfcrypt DRBG implementation.
* add support for user-supplied nonce to Versal TRNG
* add `wc_XsecureErrorToString()` to map PLM error codes to messages.
* integrate Versal EcDSA engine
* update tests to work with Versal EcDSA
If deterministic K is enabled, the tests failed here since the Versal
EcDSA engine doesn't support the SECP256R1 curve yet.
* Xilinx crypto engines like aligned memory very much
Make this a default choice, not via the user configuration.
* add Xilinx-specific `WOLFSSL_MSG()` equivalent
`WOLFSSL_XIL_MSG()` does the same as `WOLFSSL_MSG()` besides waiting for
1 second before printing to stdout, since the PLM maybe prints to same and
outputs would be mixed up.
This waiting can be disabled by defining `WOLFSSL_XIL_MSG_NO_SLEEP`.
* add option to enable DPA CounterMeasures in AES-GCM crypto engine
* add "command mode" to Xilinx bare-metal example
* update Xilinx default user settings
* add script to execute benchmarks
* add scripts to create graphics
* add Vitis 2022.1 example projects

Add x86_64 assembly code:
- BMI2
- AVX2 (using ymm, slower than BMI2)
- AVX2 of 4 similtaneous hashes
Add SHAKE128 functions and tests.
Add Absorb and Squeeze functions for SHAKE128 and SHAK256 and tests.
Add doxygen for SHA-3 and SHAKE functions.
Update other generated x86_64 assembly files to include settings.h.
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.
GCM: make borrow constant time.
AES-GCM decrypt: compare at end and constant time.
Random: array_add touchs all elements every time.
RSA-OAEP: look for padding byte in constant time (look at every byte in
array).
SP
- reduce conditional use (make them bit ops)
- Fix point adds to not use double when adding infinity to infinity
- Implement signed div as __divi3 is not constant time.
- Move check sof input variables to API.
