> DSA 2048 public key authentication 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
> Assignee: Lyor Goldstein
> Priority: Major
> Attachments: DSAKeyTests.java, maverick_id_dsa

> 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.

> Error trace:
> {code:java}
