Ssl – Tomcat ECDHE-ECDSA chiphers are not supported

opensslssltomcat7

Tomcat does not support ECDHE-ECDSA* ciphers. Configuration and version information is given below.

  • OS is CentOS 6.5 x64
  • Tomcat version is 7.0.56 Tomcat native version is 1.1.30 (Loaded APR based Apache Tomcat Native library 1.1.30 using APR version 1.3.9.)
  • Java is Oracle jdk1.8.0_20

SSL config in Tomcat server.conf:

SSLHonorCipherOrder="true" SSLDisableCompression="true"
SSLCipherSuite="ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES128-SHA256:ECDHE-ECDSA-AES128-SHA:ECDHE-ECDSA-RC4-SHA:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES256-SHA38:ECDHE-ECDSA-AES256-SHA:ECDHE-ECDSA-AES128-SHA256:ECDHE-ECDSA-DES-CBC3-SHA:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-SHA256:ECDHE-RSA-RC4-SHA:AES128-GCM-SHA256:AES128-SHA256:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-SHA384:ECDHE-RSA-AES256-SHA:AES256-GCM-SHA384:AES256-SHA256:AES256-SHA:ECDHE-RSA-AES128-SHA256:ECDHE-RSA-DES-CBC3-SHA:DES-CBC3-SHA:AES128-SHA:RC4-SHA:RC4-MD5"

But sslscan script displays as ECDHE-ECDSA* ciphers as "Failed" 

Failed    SSLv3  256 bits  ECDHE-ECDSA-AES256-GCM-SHA384
Failed    SSLv3  256 bits  ECDHE-ECDSA-AES256-SHA384

SSLLabs site also does display ECDHE-ECDSA* ciphers.

I know the mentioned bug record here https://issues.apache.org/bugzilla/show_bug.cgi?id=55915 it is closed-fixed (and verified)

sslscan script with the above configured SSLCipherSuite returns only the following ciphers as accepted.

Accepted  SSLv3  256 bits  ECDHE-RSA-AES256-SHA
Accepted  SSLv3  256 bits  AES256-SHA

Any help is appreciated.

I think its not for tomcat server.

(This cipher names are for ms servers).

In tomcat cipher using underscores(_) not hyphen(-).
