PHP socket server that uses ADH. How? -

-

i'm trying create socket server using stream_socket_server().

normal connections work fine, want make server encrypts connection without certificate. know can accomplished adh cipher, , yes, know it's theoretically less secure certificate...

the reason i'm making server in first place mock different server client connects (over this protocol, if you're wondering).

the client configured ask certificate first, , fallback adh - i've tested real thing, , connects without problems, problem socket server.

everything i've tried far has resulted in "handshake failure" error.

some of configurations i've tried:

<?php $server = stream_socket_server(         "tls://127.0.0.1:6667",         $errorno,         $errstr,         stream_server_bind | stream_server_listen,         stream_context_create(             array('ssl' => array('ciphers' => 'adh'))         )     ); ?>  <?php $server = stream_socket_server(         "tls://127.0.0.1:6667",         $errorno,         $errstr,         stream_server_bind | stream_server_listen,         stream_context_create(             array('ssl' => array('ciphers' => '-complementofall adh'))         )     ); ?>

i've tried adjust client unconditionally use adh (as second example above), testing's sake, fails.

this happens every php version i've tried, latest of 5.5.0.

any ideas?

i use tool wireshark examine bits going on wire determine going wrong handshake. without ability, going flying (or debugging) blind.

once know going wrong handshake, can figure out "why".

this error has shown on many times, seems. prominent answer issue seems restkit 0.20 — coredata: error: failed call designated initializer on nsmanagedobject class however, solution posted doesn't work me. let's start beginning: i want upload file server. want parse response make sure uploaded. if not, try again later. model has boolean variable called nsnumber *senttoserver purpose (in coredata, bool saved nsnumber ) . because don't know whether sending going successful, save entity coredata model first before sending via restkit. when post request successful, server returns json string this: {"id":14,"created":true} notice that, of course, id not set on coredata model yet, both id , created new informations model. here's model: @interface recording : nsmanagedobject @property (nonatomic, retain) nsstring * audiofilepath; @property (nonatomic, retain) nsdate * createdat; @property (nonatomic, retain) nsstring * deviceid; @
