NioTLSMessageProcessor : Can't disable certificate validation #180

Open albertpv opened 6 years ago

albertpv commented 6 years ago

When jain-sip creates TLS Sockets using NIO it seems (or due my configuration) certificate validation is done even if tried to disable it on Sip Stack roperties

I set the following options in SIP Stack properties sipStackProps.setProperty("gov.nist.javax.sip.TLS_CLIENT_AUTH_TYPE", "DisabledAll"); sipStackProps.setProperty("gov.nist.javax.sip.MESSAGE_PROCESSOR_FACTORY", NioMessageProcessorFactory.class.getName());

However NioTlsMessageChannel seems to validate certificate even if the property TLS_CLIENT_AUTH_TYPE is setup to DisabledAll

If i disable using Nio MessageChannels (comemnt out line sipStackProps.setProperty("gov.nist.javax.sip.MESSAGE_PROCESSOR_FACTORY", NioMessageProcessorFactory.class.getName()); ) then the certificate validation is not done and everything works fine.

See error below: ioSelector-TLS-10.66.172.178/5080, fatal error: 46: General SSLEngine problem sun.security.validator.ValidatorException: No trusted certificate found %% Invalidated: [Session-2, TLS_RSA_WITH_AES_256_CBC_SHA] NioSelector-TLS-10.66.172.178/5080, SEND TLSv1 ALERT: fatal, description = certificate_unknown NioSelector-TLS-10.66.172.178/5080, WRITE: TLSv1 Alert, length = 2 NioSelector-TLS-10.66.172.178/5080, fatal: engine already closed.

Would any other info be useful? (eg sipstack logs?)

BTW where can i download latest jain-sip-ri artifact? NioTlsMessageChannel i am using has a different implementation compared to the one in this repo so maybe this one fixes the problem already (DisabledAll was not handled in implementation i am using)

@albertpv it seems this issue has something to do with a certificate that isn't available in your trusted certs. I'd check if that's something you can add there.

On the other hand, if you would like to disable certificate validation, would you like to contribute a PR that addresses this issue?
