This change makes SSL virtual hosting possible. You can now load
multiple certificates for multiple domains and redbean will just
figure out which one to use, even if you only have 1 ip address.
You can also use a jumbo certificate that lists all your domains
in the the subject alternative names.
This change also makes performance improvements to MbedTLS. Here
are some benchmarks vs. cc1920749e

There aren't any special tricks to the performance imporvements.
It's mostly due to code cleanup, assembly and intel instructions
like mulx, adox, and adcx.

DESCRIPTION
|
|
|
|
Mbed TLS is a crypto library built by ARM that's been released
|
|
under a more permissive license than alternatives like OpenSSL
|
|
and is useful for interoperating with systems that require TLS
|

LOCAL CHANGES
|
|
|
|
- Reduce build+test latency from 15 seconds to 5 seconds.
|
|
|
|
- Features have been added that enable this library to produce SSL
|
|
certificates that can be used by Google Chrome. This required we
|
|
add featurces for editing Subject Alternative Names and Extended
|
|
Key Usage X.509 extension fields since upstream mbedtls can only
|
|
do that currently for Netscape Navigator.
|
|
|
|
- Local changes needed to be made to test_suite_ssl.datax due to it
|
|
not taking into consideration disabled features like DTLS.
|
|
|
|
- Local changes needed to be made to test_suite_x509parse.datax due
|
|
to the features we added for subject alternative name parsing.
|
|
|
|
- We've slimmed things down to meet our own specific local needs.
|
|
For example, we don't need the PSA code since we don't target ARM
|
|
hardware. We also don't need algorithms like camellia, blowfish,
|
|
ripemd, arc4, ecjpake, etc. We want security code that's simple,
|
|
readable, and easy to maintain. For example, the formally verified
|
|
eliptic curve diffie-helman code was 38 files and most of it was
|
|
dead code which could be consolidated into one < 1 kLOC file.
|
|
|
|
- The only breaking API change that's been made is to redefine int
|
|
arrays of things like long lists of ciphersuites to be uint8_t or
|
|
uint16_t instead when appropriate.
|
|
|
|
- Exported test code so it (a) doesn't have python as a build time
|
|
dependency, (b) doesn't print to stdout on success, (c) bundles
|
|
its dependencies inside a zip container so the tests are able to
|
|
run hermetically if the binary is scp'd to some machine, and (d)
|
|
doesn't have large amounts of duplicated generated code.
|
|
|
|
- Fix mbedtls_mpi_sub_abs() to not call malloc/free/memcpy since
|
|
it's called 11,124 times during as SSL handshake.
|
|
|
|
- Make P-256 and P-384 modulus goes 5x faster.
|
|
|
|
- Make chacha20 26% faster.
|
|
|
|
- Make base64 100x faster.
|
|
|
|
- Make gcm faster.
