Aruna Potti commented on SSHD-869:
----------------------------------
[~lgoldstein] :(Our product really does not use MINA directly, we use Open
Daylight and it has dependency on MINA. Some how Open Daylight latest version
also not using 2.1.0 or any other MINA latest versions. I am not sure why they
are not upgrading their MINA version. So we are stuck with your 0.14.0 version.
We really need a work around like if there is way to fix the sshkeys with
leading zeros? or any other standard way of generating ssh keys that would not
use leading zeros to fill the bytes.
> java.security.SignatureException: error decoding signature bytes.
