MidpSSH | SSH and Telnet client for Mobile Devices

SSH 2 is a more secure protocol and has mostly replaced SSH 1. SSH 1 is still widely available, however there are a growing number of servers that are configured to only accept SSH 2 out-of-the-box. It is not a great idea to use SSH 1 if possible because there are several exploits known in SSH 1 with one crippling exploit that on some SSH 1 servers can allow an attacker to change your root password then connect! - VERY DANGEROUS Also prone to man-in-the-middle attacks See Here

SSH 2 is more computationally intense; on some devices this can make connecting quite slow! In that case you may want to use SSH 1 instead. Or at least please try connecting with SSH 1 to see if this is the problem.

The supported ciphers for each type are:

• SSH 1
  • Blowfish
  • IDEA
  • DES3 (this is the only available cipher in the lite builds)
  • DES
• SSH 2
  • 3des-cbc

Read more about supported SSH 2 algorithms.

Public-key authentication is supported (as of beta version 1.4.8) for SSH 2.

You can enable SSH 1 on your SSH server. The method for enabling SSH 1 will depend based on your particular SSH server.

Edit your “sshd_config” file and look the “Protocol” setting. To enable SSH 1 and SSH 2 it should read:

Protocol 2,1
