@rishabhBudhouliya , I was using the sshj library to accomplish the task for ssh authentication for private keys in openssh format, sadly I couldn't achieve the desired results , so I am using the
maverick-synergy which works great, I am attaching the code below to show what the I have been working with

    public static void main(String[] args) throws IOException, InvalidPassphraseException {
        File f = new File("auth.key");
        String s;
        //TODO METHOD-1
        OpenSSHKeyV1KeyFile o = new OpenSSHKeyV1KeyFile();
        char[] arr = new char['passphase'];
//        o.init(ECDSA_Joined,"",new Pass(arr));
//        PrivateKey p = o.getPrivate();
//        String format = p.getFormat();
//        byte[] c = p.getEncoded();
//        PKCS8EncodedKeySpec pk = new PKCS8EncodedKeySpec(c);
        //TODO METHOD-2
//        OpenSSHKeyV1KeyFile o = new OpenSSHKeyV1KeyFile();
//        o.init(UNENCRYPTED_KEY,"");
//        OpenSSHPrivateKeySpec kp = new OpenSSHPrivateKeySpec(o.getPrivate().getEncoded());

        //TODO METHOD-3
//        byte[] dec = Base64.decode(RSA_Joined);
//        AsymmetricKeyParameter p = OpenSSHPrivateKeyUtil.parsePrivateKeyBlob(dec);

        SshKeyPair key = SshKeyUtils.getPrivateKey(en_RSA,"Jenkins");
        s =  SshKeyUtils.getFormattedKey(key,"");
//        String s = Base64.toBase64String(new OpenSSHPrivateKeyFile(key.getPrivateKey().getJCEPrivateKey().getEncoded()).getFormattedKey());
        //TODO BASE64-ENCODED
        FileWriter fo = new FileWriter(f);
//        s =Base64.toBase64String(c);
        fo.write(s);
        fo.close();

        //TODO PEM ENCODED
//        PemObject po = new PemObject("",c);
//        PemWriter pw = new PemWriter(new OutputStreamWriter(new FileOutputStream(f)));
//        pw.writeObject(po);
//        pw.close();

        //TODO notes[SPECIFY PATH OF SSH IN WINDOWS PROPERLY]
    }

    static class Pass implements PasswordFinder {

        char[] p;

        Pass(char[] passForKey){
            this.p = passForKey;
        }
        @Override
        public char[] reqPassword(Resource<?> resource) {
            return p;
        }

        @Override
        public boolean shouldRetry(Resource<?> resource) {
            return false;
        }
    }
}

The problem that I faced with sshj and even with bouncycastle was, the decrypted key generated is altered and isn't matching with the public key . I know this shouldn't happen may I need to dig a bit more on that.
Also I am a bit concerned about the license of
maverick-synergy maybe @MarkEWait could shed some light on that?
