             Summary: To pick up Mac/Cipher preferred values out of the default 
list
                 Key: SSHD-1142
                 URL: https://issues.apache.org/jira/browse/SSHD-1142
             Project: MINA SSHD
          Issue Type: Question
            Reporter: Susmit Sarkar


Hello Lyor,

I want to use a preferred value while configuring sftp adapter for both cipher 
and mac algos:

System.out.println(sshd.getMacFactories());

[[email protected], [email protected], 
[email protected], hmac-sha2-256, hmac-sha2-512, hmac-sha1, hmac-md5, 
hmac-sha1-96, hmac-md5-96]

Now if the customer wants a preferred value of *hmac-md5* how can I give it 
priority compared to all other default ciphers?

sshd.setMacFactoriesNames(Arrays.asList("hmac-md5"));

This only sets to hmac-md5, but the list should contain all only the hmac-md5 
will be in the priority order 1

*[ hmac-md5]*

[https://github.com/apache/mina-sshd/blob/master/docs/server-setup.md#configuring-ciphers-macs-digest]

*One can configure other security components using built-in factories the same 
way. It is important to remember though that the order of the factories is 
important as it affects the key exchange phase where the client and server 
decide what options to use out of each peer's reported preferences.*
