---------------------------------------------------------------

Then attach the ZIP and I will see if I can find a home for it in the SSHD tree - \
then suggest it to you so we can have a PR over which we can discuss the code. \
Alternatively, I am OK with placing the code under the \
{{org.apache.sshd.common.config.keys.loader.openssh}} package for now and then \
re-factor it as needed.

In any case, since you are already working on it I rely on your discretion to decide \
when you think it is ready for some initial review and/or discussion.

> Utility method to export KeyPair in OpenSSH format
> --------------------------------------------------
> 
> Key: SSHD-984
> URL: https://issues.apache.org/jira/browse/SSHD-984
> Project: MINA SSHD
> Issue Type: New Feature
> Affects Versions: 2.4.0
> Reporter: David Ostrovsky
> Priority: Minor
> 
> There are ongoing efforts in Gerrit Code Review and JGit projects to remove \
> dependency on JSch library: [1], [2]. Instead, MINA SSSD should be used on both: \
> client and server sides. One difficulty we are facing is the fact the MINA SSHD \
> currently doesn't provide any means to export generated KeyPair in OpenSSH format. \
> Thomas Wolf added recently the ability to read encrypted OpenSSH private keys in \
> context of SSHD-708. With JSch this code would do the job:
> {code:java}
> public static com.jcraft.jsch.KeyPair genSshKey() throws JSchException {
> JSch jsch = new JSch();
> return KeyPair.genKeyPair(jsch, KeyPair.ECDSA, 256);
> }
> public static String publicKey(com.jcraft.jsch.KeyPair sshKey, @Nullable String \
> comment) throws UnsupportedEncodingException {
> ByteArrayOutputStream out = new ByteArrayOutputStream();
> sshKey.writePublicKey(out, comment);
> return out.toString(US_ASCII.name()).trim();
> }
> public static byte[] privateKey(com.jcraft.jsch.KeyPair keyPair) {
> ByteArrayOutputStream out = new ByteArrayOutputStream();
> keyPair.writePrivateKey(out);
> return out.toByteArray();
> }
> {code}
> [1] [https://bugs.eclipse.org/bugs/show_bug.cgi?id=540727]
