Invalid private key generated with OpenSSH

[lordofthejars]

I am trying to use a private key generated with OpenSSH, but I always get an invalid private key exception. I am using Java8 and jcabi-ssh 1.5. The private key is (it is for testing purposes):

-----BEGIN RSA PRIVATE KEY-----
8glbkhKvJ9OAOwX7iy7gcWzBLsENZouu/KIUg3yRIUQruM04Dvrd1Dv9mWifVHWT
1mAqeln1MRi3vR841NEhGD4vF3FmxY6tX+SYijEQ6RYcIthNTmc2GHf0hW2/yiny

-----END RSA PRIVATE KEY-----

And the code I am using:

String privateKey = IOUtils.toString(
                JSchTest.class.getResourceAsStream("/org/arquillian/cube/containerobject/SshdContainer/test_rsa"), "UTF-8");
        System.out.println(privateKey);
        String hello = new Shell.Plain(
                new SSH(
                        sshdContainer.getIp(), 2222,
                        "test", privateKey
                        )
        ).exec("echo 'Hello, world!'");

Anything that I am going wrong, do I need another dependency?

@yegor256 please do something about this issue

[yegor256]

@lordofthejars looks correct to me. what exactly do you see? can you post stacktrace here?

Sorry for being a bit late, JavaOne thing hehehe:

Any idea? Maybe I need to install something?

[MathieuGingras]

Any news on this ? I got the same error but I know the key is valid, since I use it almost everyday

[lordofthejars]

No answer, I tried everything but didn't work and I decided to give up.

[MathieuGingras]

Disappointed to hear this but thanks for the info !

If it may interest others, I was able to fix my problem. It turns out that my private key need a passphrase. By switching to 2.0-snapshot, and using the new constructor (https://github.com/jcabi/jcabi-ssh/issues/50) I was able to make it work.

I have the same problem. It was my mistake. I forget to put a "\n" at the end of each line, in my key string.

I have the same problem. It was my mistake. I forget to put a "\n" at the end of each line, in my key string.

Same with me, I had to edit my private key file (.ppk) to replace the \r with an \n, at the end of each line. I did this easily in Notepad++ with Find/Replace, Extended search mode, find "\r" and replace with "\n".
