Unable to create HTTPS connection when some opnessl cipher suite with DHE are used ---------------------------------------------------------------------------------- Key: ELY-386 URL: https://issues.jboss.org/browse/ELY-386 Project: WildFly Elytron Issue Type: Bug Components: SSL Affects Versions: 1.0.2.Final Environment: Oracle java 1.8.0_66 Reporter: Martin Choma Can't configure OpenSSL cipher suites EXP-DHE-RSA-DES-CBC-SHA, DHE-RSA-DES-CBC-SHA, DHE-RSA-DES-CBC3-SHA, EXP-DHE-DSS-DES-CBC-SHA, DHE-DSS-CBC-SHA, DHE-DSS-DES-CBC3-SHA [1] for HTTPS connection. Seems like everlasting problem DHE vs. EDH [2] - these cipher suites don't work neither in EAP6. IMHO problem is in MechanismDatabase.properties, where these DHE cipher suite are mapped to openssl EDH cipher suite what contradict openssl documentation [1]: {code} SSL_DHE_RSA_EXPORT_WITH_DES40_CBC_SHA = alias:TLS_DHE_RSA_EXPORT_WITH_DES40_CBC_SHA SSL_DHE_RSA_WITH_DES_CBC_SHA = alias:TLS_DHE_RSA_WITH_DES_CBC_SHA SSL_DHE_RSA_WITH_3DES_EDE_CBC_SHA = alias:TLS_DHE_RSA_WITH_3DES_EDE_CBC_SHA TLS_DHE_RSA_EXPORT_WITH_DES40_CBC_SHA = EXP-EDH-RSA-DES-CBC-SHA,DHE,RSA,DES,SHA1,SSLv3,true,EXP40,false,40,56 TLS_DHE_RSA_WITH_DES_CBC_SHA = EDH-RSA-DES-CBC-SHA,DHE,RSA,DES,SHA1,SSLv3,false,LOW,false,56,56 TLS_DHE_RSA_WITH_3DES_EDE_CBC_SHA = EDH-RSA-DES-CBC3-SHA,DHE,RSA,3DES,SHA1,SSLv3,false,HIGH,true,168,168 SSL_DHE_DSS_EXPORT_WITH_DES40_CBC_SHA = EXP-EDH-DSS-DES-CBC-SHA,DHE,DSS,DES,SHA1,SSLv3,true,EXP40,false,40,56 SSL_DHE_DSS_WITH_DES_CBC_SHA = EDH-DSS-DES-CBC-SHA,DHE,DSS,DES,SHA1,SSLv3,false,LOW,false,56,56 SSL_DHE_DSS_WITH_3DES_EDE_CBC_SHA = EDH-DSS-DES-CBC3-SHA,DHE,DSS,3DES,SHA1,SSLv3,false,HIGH,true,168,168 {code} Note that MechanismDatabase.properties is inconsistent in mapping DHE cipher suites to openssl cipher suites, as there also exist couple of them which map DHE to DHE, for example {code} TLS_DHE_RSA_WITH_AES_128_CBC_SHA256 = DHE-RSA-AES128-SHA256,DHE,RSA,AES128,SHA256,TLSv1.2,false,HIGH,true,128,128 TLS_DHE_RSA_WITH_AES_256_CBC_SHA256 = DHE-RSA-AES256-SHA256,DHE,RSA,AES256,SHA256,TLSv1.2,false,HIGH,true,256,256 TLS_DHE_RSA_WITH_AES_128_GCM_SHA256 = DHE-RSA-AES128-GCM-SHA256,DHE,RSA,AES128GCM,AEAD,TLSv1.2,false,HIGH,true,128,128 TLS_DHE_RSA_WITH_AES_256_GCM_SHA384 = DHE-RSA-AES256-GCM-SHA384,DHE,RSA,AES256GCM,AEAD,TLSv1.2,false,HIGH,true,256,256 {code} In MechanismDatabase.properties is also said that ??Note that all EDH ciphers automatically get a DHE OpenSSL-style alias (and vice-versa)?? I think this JIRA contradict this comment. Last thing, based on [1] shouldn't be SSL_DHE_DSS_WITH_DES_CBC_SHA defined as SSL_DHE_DSS_WITH_DES_CBC_SHA = DHE-DSS-CBC-SHA,DHE,DSS,DES,SHA1,SSLv3,false,LOW,false,56,56 ?
