Please add support for host keys hashed? with ecdsa-sha2-nistp256.
When I do a ssh user@localhost on my openSuSE 12.1 box and trust the host, the entry in the ~/.ssh/known_hosts file looks like:
|1|uMRj4MI3SEWPTtQfK2PBDbc3KRM=|0JO3FUy67eeKiiWotrnY3A/DNT8= ecdsa-sha2-nistp256 AAAAE2Vj...
and JSch is unable to detect that the host key for user@localhost is already accepted
