[jira] [Commented] (SSHD-506) Add support for aes128/256-gcm ciphers

    [ https://issues.apache.org/jira/browse/SSHD-506?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16951882#comment-16951882 ] 

Lyor Goldstein commented on SSHD-506:
-------------------------------------

My understanding of the RFC is that the _AAD_ value to use for the cipher is the packet length.
