This is the simplest direct socket implementation of the MySQL STARTTLS
protocol.
This is a binary protocol, so it requires a new stream based send
(instead of the current line based send).
openssl/master branch now supports mysql STARTTLS in s_client
This patch adds support to call and use that s_client support to run
most, but not all (pfs, client simulation) tests.
The socket implementation is stubbed, but not yet functional.
The Postgres protocol uses STARTTLS with a custom start packet. This
functionality is supported by openssl s_client in the current openssl
master branch but not yet in any released version.
This patch detects whether the given openssl binary supports postgres
and runs the default tests against a postgres server.
Example of no openssl support:
~/bin/testssl$ ./testssl.sh --quiet
--openssl=/opt/openssl/openssl-1.1.0c/bin/openssl --starttls=postgres
test.postgres.server.com:5432
Start 2016-12-07 18:03:24 -->> ip.add.re.ss:5432
(test.postgres.server.com:5432) <<--
Fatal error: Your /opt/openssl/openssl-1.1.0c/bin/openssl does not
support the "-starttls postgres" option
Example of openssl support:
~/bin/testssl$ ./testssl.sh --quiet
--openssl=/opt/openssl/openssl-2016-12-07/bin/openssl --startt ls=postgres
test.postgres.server.com:5432
Start 2016-12-07 18:06:03 -->> ip.add.re.ss:5432
