* Signature wrapper improvements to eliminate mallocs/frees unless small stack is used. If small stack is used only one allocation is done based on actual max (was previously was allocating too much and in the encoding case was reallocating a second buffer).
Fix asn.c and rsa.c small stack to not have large stack variables.
In RSA code don't load or store dP, dQ or u when using RSA_LOW_MEM as
they are not used.
Fix SP to recognize RSA_LOW_MEM means to use d, private exponent.
Fix wc_CheckRsaKey to work with SP.
Fix sp_int to support mp_set_int for wc_CheckRsaKey().
1. In wc_DhGenerateParams(), changed the call to mp_prime_is_prime() to
mp_prime_is_prime_ex().
2. In wc_MakeDsaParameters(), changed the call to mp_prime_is_prime() to
mp_prime_is_prime_ex().
3. Added wc_CheckProbablePrime_ex in RSA that also takes an RNG to call
mp_prime_is_prime_ex(). If RNG is NULL, call mp_prime_is_prime().
4. Rewrite wc_CheckProbablePrime() in terms of
wc_CheckProbablePrime_ex().
1. Update gitignore with some more VS outputs.
2. Update the Windows IDE user settings with FIPSv2 settings.
3. Remove redundant _InitHmac() function from ssl.c.
4. In wc_DhGenerateParams(), initialize the groupSz and bufSz to 0.
5. In wc_DhExportParamsRaw(), initialize pLen, qLen, and gLen to 0.
6. In wc_MakeRsaKey(), initialize isPrime to 0.
7. In ecc_test_make_pub(), initialize exportBuf and tmp to NULL and initialize the ECC key before any chance of trying to free it.
8. In fips_test.h header, update types.h include to use the wolfCrypt types rather than ctaocrypt types.
9. In fips_test.h header, change the visibility tags on all the function prototypes to use the WOLFSSL tags rather than CYASSL.
10. Change the wolfCrypt visibility tags to use CyaSSL's tags for old FIPS and the regular tags for new FIPS and non-FIPS builds.
1. Added APIs to perform RSA-PSS verify and padding operation in the same call.
2. Change to RsaPSS sign and verify to pick the proper salt length if the key is 1024-bits and the hash is SHA-512.
* Added support for ECC, AES-GCM and HMAC (SHA-224 and SHA3).
* Fixes for Nitrox V with TLS.
* ECC refactor for so key based `r` and `s` apply only when building with `WOLFSSL_ASYNC_CRYPT`.
* ECC refactor for `e` and `signK` to use key based pointer for Nitrox V.
* Improved the Nitrox V HMAC to use start, update and final API's instead of caching updates.
* Fix for Intel QuickAssist with unsupported HMAC hash algos using `IntelQaHmacGetType` (such as SHA3).
* Added new API `wc_mp_to_bigint_sz` to zero pad unsigned bin.
* Fix for AES GCM to gate HW use based on IV len in aes.c and remove the gate in test.c.
* Implemented workaround to use software for AES GCM Nitrox V hardware and 13 byte AAD length for TLS.
* New debug option `WOLFSSL_NITROX_DEBUG` to add pending count.
* Added PK callback context tests for client/server examples (`SetupPkCallbackContexts`).
* Added new test define for `TEST_PK_PRIVKEY` to allows simulating hardware based private key.
* Added new test.h function for loading PEM key file and converting to DER (`load_key_file`).
* Added way to get private key signature size (`GetPrivateKeySigSize`).
* Added new ECC API `wc_ecc_sig_size_calc` to return max signature size for a key size.
* Added inline comments to help track down handshake message types.
* Cleanup of RSS PSS terminating byte (0xbc) to use enum value.
* Fixed bug with PK callback for `myEccVerify` public key format.
* Fixed bug with PK callback for ED25519 verify key buffer in DoServerKeyExchange.
1. Added some bounds checking on the ciphertext passed into the RSA decrypt function. NIST SP 800-56B specifies that the ciphertext shouldn't be a number larger than the modulus.
2. Added an API test to check that the direct RSA decrypt function returns an error with a "bad" message.
3. Added an ifndef guard to disable the bounds check. Default is to keep the bounds check.
4. RSA Decrypt bounds check only checked the first time into wc_RsaFunction().
--enable-sp-math to include minimal implementation of MP (only with
--enable-sp.)
Add futher functionality for ECC (conditionally compiled):
- check key
- is point on curve
- API to add and double projective points
- API to map from project to affine
- Uncompress point (including sqrt)
Some configuration options will not work with SP math - configure.ac
detects this and errors out.
Change test code to better support SP sizes only.
A recent change to the RSA key generation process is capping the number of attempts of finding a probable prime to a multiple of the prime's size, in FIPS builds. This means it might fail once in a while. (It could also fail for a couple other reasons but this is the most likely.) The API is changed to retry key generation until it succeeds. Non-FIPS builds keep trying until they find a prime.
1. White space changes. Converting tabs to spaces.
2. Add some comments explaining where a loop bound came from.
3. Added parameter checks to a function.
