et.schmizz.sshj.userauth.UserAuthException: Exhausted available authentication methods

Hi,
Let me explain my problem !
I am trying to authenticate using rsa keys & passphrase

I'm using sshj 0.23.0 & bc 1.59

Let me know if I do something wrong !!

Thanks !

**Code used:**

`privateKey = readFile("../clef/id_rsa");`
`publicKey = readFile("../clef/id_rsa.pub");`
`passphrase = readFile("../clef/passphrase");`
`System.out.println("privateKey = " + privateKey);`
`System.out.println("publicKey = " + publicKey);`
`System.out.println("passphrase = " + passphrase);`

`OpenSSHKeyFile key; `
`key = new OpenSSHKeyFile();`
`key.init(new File("../clef/id_rsa"),new StaticPasswordFinder(passphrase)); `
`try`
`{`
` System.out.println("Authentificate with user & passphrase" + user + " (key)");`
` ssh.authPublickey(user, key);`
` System.out.println("Authentificate with user & passphrase" + user + " (key) DONE ");`
`}`
` catch (UserAuthException e)`
`{`
` System.out.println(e.getMessage());`
` e.printStackTrace();`
`}`

**And the output log**
