This is using the openssl binary which, despite it's contained in the
deps, would probably miss all it's environment. It is just prone to
failure and thus is not worth it.
Switch to SHA1, which match internal openssl hardcoded algo.
In most case, won't even be noticed
- priority on user input (default_md)
- fallback on system config
- fallback on this default value
Recent system reject MD5 digest, noticed in bug36732.phpt failure.
While SHA1 is better than MD5, SHA256 is recommenced,
and defined as default algo in provided configuration on
recent system (Fedora 21, RHEL-7, ...). But the idea is to
keep in sync with openssl internal value for PHP internal value.
- New "SNI_server_certs" context option maps host names to
appropriate certs should client handshakes advertise the
SNI extension:
$ctx = stream_context_create(["ssl" => [
"local_cert" => "/path/to/cert.pem",
"SNI_server_certs" => [
"domain1.com" => "/path/to/domain1.pem",
"*.domain2.com" => "/path/to/domain2.pem",
"domain3.com" => "/path/to/domain3.pem"
]
]]);
- Prefixing a "*." will utilize the matching cert if a client
requests the primary host name or any subdomain thereof. So
in the above example our "domain2.pem" will be used for both
requests to "domain2.com" -and- "subdomain.domain2.com"
- The "SNI_server_certs" ctx option has no effect for client
streams.
- SNI support is enabled by default as of 5.6 for both servers
and clients. Servers must specify the "SNI_server_certs" array
to actually use the SNI extension, though.
- If the `"SNI_enabled" => false` ctx option is also passed then
"SNI_server_certs" has no effect.
- While supporting SNI by itself is enough to successfully
negotiate the TLS handshake with many clients, servers MUST
still specify a "local_cert" ctx option or run the risk of
connection failures from clients that do not support the SNI
extension.
- All streams-related code now lives in xp_ssl.c. Previously
stream code was split across both openssl.c and xp_ssl.c
- Folded superfluous php_openssl_structs.h into xp_ssl.c
- Server-specific options now set on SSL_CTX instead of SSL
- Deprecate SNI_server_name ctx option
- Miscellaneous refactoring
Previously the "capture_peer_cert" SSL context option only
captured the peer's certificate if the verification routine
succeeded.
By also capturing the on verify failure applications have the
ability to parse the cert and ask users whether they wish to
proceed given the information presented by the peer.
