--------------------------

             Summary: DSA 2048 keys fails
                 Key: SSHD-945
                 URL: https://issues.apache.org/jira/browse/SSHD-945
             Project: MINA SSHD
          Issue Type: Bug
    Affects Versions: 2.1.0
            Reporter: Logan
         Attachments: DSAKeyTests.java

While RSA 1024, 2048 and DSA 1024 keys succeed, DSA 2048 fails with error trace 
listed below. I am trying to figure out if the issue is related to DSA keys 
generated by JDK or apache SSHD. Attached is the test case. 

 

Tests with JSch API also fail with DSA 2048 keys.
