Commit 6467de5 added some timing resistance to ECC shared secret
agreement. It involved adding an RNG object to the ecc keys so
a random z value can be added to the mix. The older FIPS release
has ECC outside the boundary, so it uses the new ECC code. FIPSv2
has ECC inside the boundary, but all the TLS code checks for that
version of FIPS and leaves out the calls to the new functions as
it is using an older version of ecc.c. FIPS Ready uses the latest
version of ecc.c but compiles as FIPSv2. So, the code outside of
the crypto layer is treating ECC as FIPSv2 and not calling the new
functions, but the crypto layer assumes the RNG should be present,
and errs out on testing.
1. Added a separate option for FIPS Ready to the enable-fips
configure option. `--enable-fips=ready`. It will treat FIPS
Ready as the next kind of FIPS release. FIPS Ready will be
treated like FIPS v3 in the build.
2. Changed the C preprocessor checks for FIPS version 2 to be
checks for not version 2, with respect to ECC Timing Resistance
and FIPS builds.
An RNG is required for shared secret calculation now.
Use wc_ecc_set_rng() to set an RNG against the ECC object.
ECC verification does not need timing resistance and does not randomize
z ordinates.
Fix SkipInt() to work with DSA.
Fix protection around SetBitString16Bit() - when WOLFSSL_CERT_GEN and
WOLFSSL_CERT_EXT defined is only use.
WOLFSSL_RSA_VERIFY_ONLY and PSS means testing of PSS won't work.
Fix g++ build around ASN1_SEQUENCE - const variable required to be
initialized.
* Added TLS v1.3 sniffer support using static ephemeral key.
* Add support for using a static ephemeral DH and ECC keys with TLS v1.3 using `WOLFSSL_STATIC_EPHEMERAL`.
* Adds new API's `wolfSSL_CTX_set_ephemeral_key` and `wolfSSL_set_ephemeral_key`.
* Expanded TLS extension support in sniffer.
* Refactor of the handshake hashing code.
* Added parameter checking to the TLS v1.3 key derivations (protects use of "DoTls13Finished" if handshake resources have been free'd).
* Added support for loading DH keys via `wc_DhImportKeyPair` and `wc_DhExportKeyPair`, enabled with `WOLFSSL_DH_EXTRA`.
* Added sniffer documentation `sslSniffer/README.md`.
* Refactor the PEM saving code in `test.c`, so its not using large 4K buffer and calculates based on DER.
* Enable ECC key generation test even without `WOLFSSL_KEY_GEN`.
* Added `ECC_KEYGEN_SIZE` macro for ECC key generation testing.
* Refactor ECC DER key generation to use `ECC_BUFSIZE`.
