- The `ssl->dtlsMtuSz` value is the maximum possible size of the DTLS record layer. We read `ssl->dtlsMtuSz + 100` in case peer has slightly different MTU set.
- The `-u` option in the examples takes the value of the MTU size.
- MTU tests are added in `tests/test-dtls-mtu.conf`
Encrypts with ChaCha20-Poly1305 or AES-GCM.
Two keys in rotation.
Key used for encryption until ticket lifetime goes beyond expirary
(default 1 hour). If key can still be used for decryption, encrypt with
other key.
Private random used to generate keys.
- explicit conversions
- not all curves available for wolfSSL_CTX_set1_groups_list
- group funcs depend on HAVE_ECC
- `InitSuites` after `ssl->suites` has been set
- I observed that client TX throughput < client RX throughput, but server TX
throughput > server RX throughput. Turns out this is just a typo in the
printing of the stats. The RX stat was being printed as the TX stat and vice-
versa.
- I added a note to scripts/benchmark.test about a 2 second sleep we do waiting
for the server to come up. If you were to time this script with the time
command, you'll see that 2 seconds in the result, which might be confusing
if you didn't realize the sleep was there.
1. Fixed a couple possible 0 byte allocations.
2. Fixed a couple missed frees due to error conditions.
3. Fixed a possible double free.
To recreate:
$ scan-build ./configure --disable-shared --enable-opensslextra=x509small --disable-memory

```
./examples/server/server -H overrideDateErr -A ./certs/ca-cert.pem -k ./certs/server-key.pem -c ./certs/intermediate/server-chain.pem &
./examples/client/client -D -A ./certs/ca-cert.pem -k ./certs/client-key.pem -c ./certs/intermediate/client-chain.pem
```
1. Rearrange the deprecation cryptodev option so it doesn't overwrite the cryptocb option, and so it doesn't break its case in the build-test.
2. Fix the content length in the sample HTTP used by the example server.
3. Disable OCSP stapling in the example server if RSA is disabled.
4. Fix a variable in asn.c that was declared in the middle of its scope.
5. Retag the xmalloc, xrealloc, xfree functions used in the memory test as WOLFSSL_API like all the other allocators, instead of extern.
1. The combination enable-all and disable-rsa breaks some of the
testing. Added the NO_RSA guards as appropriate.
2. Disabled the OCSP stapling and CRL tests when RSA is disabled as they
use test certificates with RSA keys.
Added an API for enabling the Trusted CA Key Indication extension from
RFC6066 section 6. If the server doesn't have a match for the client,
the client will abandon the session.
Fix wc_ecc_fp_free() to be called when using HAVE_STACK_SIZE.
Increase size of replyin client.c so all HTTP reply is displayed.
Fix api.c to support only Ed25519 (not RSA and ECC)
Fix suites.c to detect when CA for client won't work (Ed25519 only)
For Static Memory add debugging and small profile.
Also allow realloc to be called with NULL.
Add more Ed25519 certs and keys.
Fix names of Ed25519 filenames for client and server.

Enable WOLFSSL_STATIC_MEMORY_SMALL if low resource and no RSA.
1. Add a second select for tx.
2. Revised tcp_select to work for either rx or tx.
3. Updated client and server to use new tcp_select_tx() for checking the
tx socket if the nonblocking connect/accept would block on transmit.
1. Fix testing issue with a client using the SCSV cipher suite to indicate desire for renegotiation.
2. Add indication to both the server and client examples that the renegotiation was successful.
1. Add the server side renegotiation flag to the secure renegotiation option.
2. Changed the AddEmptyNegotiationInfo so it doesn't create an extension, just adds a reply if SCR is enabled.
3. Fix the server's reaction to the client sending the SCR extension.
1. Add enables to the example server for turning on secure renegotiation.
2. Add encryption assists to the handhshake message handler functions.
3. Add a hello request message function. Includes handshake timing pre/postambles.
When loading DH domain parameters into a CTX, test the prime
immediately. When loading them into a session, test the prime right
before using it during the handshake. Sessions that get their prime from
their context do not need to test their prime. Added a function to
disable testing the prime in a session. The goal is to speed up testing
as every single test case loads DH parameters whether they are used or
not.
1. Define Timeval in callbacks.h if the file sys/time.h is missing.
2. When picking the correct strtok() function, take into account MINGW64.
3. In the example server, changed the call to SSL_accept_ex() as it doesn't exist. Using wolfSSL_accept_ex(). Only a problem when setting WOLFSSL_CALLBACKS.
4. PickHashSigAlgo() is missing a ; when WOLFSSL_CALLBACKS is set.
It is highly recommended that the PSK be different for each protocol.
Example callback already returns a different key for TLS 1.3.
New callback includes the ciphersuite, as a string, to use with the key.
Allows configurations without RSA, DH and ECC but with Curve25519
algorithms to work with SSL/TLS using X25519 key exchange and Ed25519
certificates.
Fix Ed25519 code to call wc_Sha512Free().
Add certificates to test.h and fix examples to use them.
1. AesGcmEncrypt_ex requires the RNG, remove function if RNG disabled.
2. Fix a couple function name changes in the example server.
3. Removed the old FIPS wrapping added to dh.h, was redundant.
4. Move include of random.h in the aes.h file.
5. Fix where ecc.c was being left out of old FIPS builds.
6. Exclude the AES-GCM internal IV test case when building without the RNG.
7. Fix api test where AES-GCM Encrypt was called with a too-long IV in old FIPS mode. Non-FIPS and new FIPS are allowed longer IVs.
1. Moved the rest of the FIPS algorithms to FIPSv2.
2. Updated the fips-check and autogen scripts.
3. Updated the automake include for the crypto files.
4. Updated the example server to use the wolfSSL API and wolfSSL-based OpenSSL compatibility layer.
5. Added error code for the SHA-3 KAT.
6. Updated an test case in the API test for AES-GCM encrypt that is now considered a success case, but the FIPS mode was still treating as a failure.
* Added test for certificate with bad alt name containing a null character mid byte stream.
* Fix for issue with suites unit test where last arg in file doesn't conain data for a param, causing it to skip test.
* Fix for last test in tests/test.conf not being run for `TLSv1.2 RSA 3072-bit DH 3072-bit`.
* Moved the `tls-cert-fail.test` tests into the new expected failure suite test (`./tests/test-fails.conf`). Now it explicilty checks RSA and ECC for the no signer and no sig tests.
Support Draft 28: able to compile code to return BAD_BINDER if no PSKs
match and certificates not to be used.
Change key share implementation to use server preference - server now
checks each client key share's group is in supported_groups extension.
Client and server examples modified to support server preference.
Application can set client's and server's supported groups by rank.
Server's supported groups is sent back in encrypted_extensions if
preferred group is not in client's list - able to be turned off at
compile time.
Application can query server's preferred group from client.
Able to compile using 0x0304 as version instead of draft version.
Fix state machine in TLS 1.3 to support unexpected hello_retry_request.
Also fixes non-blocking.
Fix resumption to use the named group from session.

for AVX1.
Fix Curve25519 code to use define instead.
Change Curve25519 to memset all object data on init.
Change Poly1305 to put both sizes into one buffer to avoid a second call
to wc_Poly1305Update().
Added WOLFSSL_START and WOLFSSL_END API and calls to show time of
protocol message function enter and leave to analyse performance
differences.
Moved Curve25519 code in KeyShare extension out of general ECC code.
* 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.

* Cleanup to combine all certificate subject information into global `certDefaultName`.
* Updated cert request info to use wolfSSL instead of Yassl.
* Cleanup to combine keyUsage into `certKeyUsage` and `certKeyUsage2`.
* Re-number error codes in rsa_test.
* Moved the certext_test after the ecc_test, since it uses a file generated in `ecc_test_cert_gen`.
1. Make the decrypt and verify MAC failure cases behave the same with
respect to DTLS messages. It should pretend the message never happened.
2. Allow the echoclient to survive the echoserver sending a message with
a bad MAC.
3. Allow the server to survive the client sending a message with a bad MAC.
1. Since multicast's only cipher suite uses null cipher

1. Update the example client and server to test DTLS-SCTP.
2. Modify the test.h functions for setting up connections to allow
for a SCTP option.
3. Update other examples to use the new test.h functions.
4. Removed some prototypes in the client header file were some functions
that should have been static to the client.c file and made them static.
1. Added the usual cipher suite changes for the new suite.
2. Added a build option, WOLFSSL_ALT_TEST_STRINGS, for testing
against GnuTLS. It wants to receive strings with newlines.
3. Updated the test configs for the new suite.
Tested against GnuTLS's client and server using the options:
$ gnutls-cli --priority "NONE:+VERS-TLS-ALL:+AEAD:+ECDHE-ECDSA:+AES-128-CCM:+SIGN-ALL:+COMP-NULL:+CURVE-ALL:+CTYPE-X509" --x509cafile=./certs/server-ecc.pem --no-ca-verification -p 11111 localhost
$ gnutls-serv --echo --x509keyfile=./certs/ecc-key.pem --x509certfile=./certs/server-ecc.pem --port=11111 -a --priority "NONE:+VERS-TLS-ALL:+AEAD:+ECDHE-ECDSA:+AES-128-CCM:+SIGN-ALL:+COMP-NULL:+CURVE-ALL:+CTYPE-X509"
To talk to GnuTLS, wolfSSL also needed the supported curves option
enabled.
