ssh2

ssh2 #
SSH and SFTP client for Flutter. Wraps iOS library NMSSH and Android library JSch. This is a fork of flutter_ssh: https://github.com/shaqian/flutter_ssh
Wraps iOS library NMSSH and Android library JSch.
Installation #
Add ssh2 as a dependency in your pubspec.yaml file.
Known issue #

Older Gradle versions are not supported due to incompatibilities with the newer JSch dependency. This release was tested with Gradle version 7.0.2.

Usage #
Create a client using password authentication #
import 'package:ssh2/ssh2.dart';

var client = new SSHClient(
host: "my.sshtest",
port: 22,
username: "sha",
passwordOrKey: "Password01.",
);

OpenSSH keys
Recent versions of OpenSSH introduce a proprietary key format that is not supported by most other software, including this one, you must convert it to a PEM-format RSA key using the puttygen tool. On Windows this is a graphical tool. On the Mac, install it per these instructions. On Linux install your distribution's putty or puttygen packages.

Temporarily remove the passphrase from the original key (enter blank password as the new password)
ssh-keygen -p -f id_rsa
convert to RSA PEM format
puttygen id_rsa -O private-openssh -o id_rsa_unencrypted
re-apply the passphrase to the original key
ssh-keygen -p -f id_rsa
apply a passphrase to the converted key:
puttygen id_rsa_unencrypted -P -O private-openssh -o id_rsa_flutter
remove the unencrypted version:
rm id_rsa_unencrypted
