Token2Shell/MD now supports all the host key types used in OpenSSH including ECDSA and Ed25519!
/in Token2Shell/MDElliptic curve cryptography (ECC) is becoming popular as it can achieve equivalent or higher level of security using less computing power than traditional methods (ex. RSA). OpenSSH and other poplar SSH servers support ECC based key exchange methods and host key types such as ECDH, ECDSA and Ed25519.
Token2Shell/MD now also supports ECC based methods that are fully compatible with OpenSSH. The following summarizes new features and changes in version 10.9.0:
ecdsa-sha2-nistp256, ecdsa-sha2-nistp384, ecdsa-sha2-nistp521, ssh-ed25519
Please note that Token2Shell/MD uses the same private/public key file format as OpenSSH. Thus if you already have private keys generated with ssh-keygen, you can simply copy them to Token2Shell/MD Home Folder (...\Token2Shell\ssh\keys) or import them via "Import" menu. You can also generate new private keys within Token2Shell/MD.
curve25519-sha256@libssh.org, ecdh-sha2-nistp256, ecdh-sha2-nistp384, ecdh-sha2-nistp521, diffie-hellman-group-exchange-sha256
Please note that Address Book entries have their own SSH related settings. Thus you need to update existing entries individually if you want to use the newly added key types and methods for the stored server settings.
Address Book entries in Token2Shell/MD correspond to plain XML text files under its Home Folder (...\Token2Shell\address.book). So if you're familiar with using a scripting language such as PowerShell, or have a text editor capable of opening multiple files and replacing a certain text on all of them, you should be able to update your Address Book entries more easily.
If your terminal output is not vertically aligned correctly even if you've selected a mono-spaced font, try setting this option off. After changing this option, you need to re-connect to the server as this option is applied only when a new session is started.

Token2Shell/MD now even supports ZModem and XModem!
/in Token2Shell/MDZModem/XModem can be handy as files are sent or received over the current connection without depending on additional daemons or background service software. You just need ZModem/XModem executables (ex. lrzsz) that are readily available for almost all Unix and Unix-like servers. They are also still widely used for embedded devices for updating firmware or retrieving log files.
All in all, Token2Shell/MD now got you covered! The following summarizes new features and changes in version 10.8.0:
Serial devices can now be directly connected from Token2Shell/MD
/in Token2Shell/MDToken2Shell/MD version 10.7.0 is now available. Along with bug fixes and minor enhancements, the new version now natively supports serial communication. The following summarizes new features and changes.
Please note that the serial communication support in the new version uses a different URL scheme name 'serial://' instead of 'com://' that we used in our other products. Hence, address book entries for serial devices are not compatible.
We decided to use a new scheme as the new serial device support in Token2Shell/MD is built around a port 'name' instead of a port 'number'. Such fundamental difference makes an address book entry incompatible. Thus we wanted to at least keep the address book entries from other programs intact by using a new scheme.
Token2Shell/MD version 10.6.0 improves handling touch gestures and context menus
/in Token2Shell/MDToken2Shell/MD version 10.6.0 is now live on Windows Store. The following summarizes new features and changes.
If you don't need to specify a port number with an IPv6 address, you can just enter its raw hexadecimal representation with colons. For example, when you want to enter an IPv6 address, '2001:0db8:0000:0000:0000:ff00:0042:8329', with a user ID, 'myid':
When you need to specify a port number, the address must be enclosed with brackets ('[' and ']'). For example, to append a port number 1234:
Token2Shell/MD now supports direct PDF file printing over SSH or TELNET
/in Token2Shell/MDToken2Shell/MD version 10.5.0 is now live on Windows Store. The following summarizes new features and changes.
Token2Shell/MD version 10.4.0 now available on Windows Store
/in Token2Shell/MDToken2Shell/MD version 10.3.0 now available on Windows Store
/in Token2Shell/MDIn order to maximize transfer speed, Token2Shell/MD seamlessly makes use of both SFTP and SCP. If the server does not support SCP or cannot handle high-speed SFTP, Token2Shell/MD automatically falls back to the standard SFTP. File uploading can also be started via drag-and-drop or paste directly from Windows File Explorer.
While transferring files or using X11 forwarding, please don't minimize Token2Shell/MD to the Taskbar. It may trigger Windows OS to pause running the app altogether.
In order to properly use X11 forwarding, you need to separately run an X server such as VcXsrv (http://sourceforge.net/projects/vcxsrv/) or Xming (http://www.straightrunning.com/XmingNotes/). Also, as mentioned above, please don't minimize Token2Shell/MD to the Taskbar while using X11 forwarding.
This option is not available for Windows 10 Mobile since it requires a separate X server running in the background and such background task is not allowed in the Mobile.
Token2Shell/MD is now Mobile and Continuum Ready!
/in Token2Shell/MDWindows 10 Mobile is not yet officially released, however we are happy to announce that you can now test drive Token2Shell/MD on smartphone with Windows 10 Mobile preview versions.
When you launch Token2Shell/MD from a smartphone, each session terminal is maximized to make full use the available screen area. However, when it's in Continuum mode with higher screen resolution, each session terminal can be freely floated and moved around the screen; just like running Token2Shell/MD on a desktop PC. It even supports setting its desktop background image and opening translucent terminal windows.
Have not yet heard about the Continuum? Here are some of the videos demonstrating the Continuum in Windows 10 Mobile:
As mentioned, Windows 10 Mobile is not yet officially released and Token2Shell/MD is built and tested against those preview versions hence there may be more glitches and unexpected bugs. If you do find such problems, just drop us a line! We'll have it fixed right away and make sure everything works flawlessly when the official version of Windows 10 Mobile is available.
By the way, buying Token2Shell/MD from Windows Store allows you to install it on both PC and smartphone without additional cost. So if you're in Windows 10 Mobile Insider program or in the market for an SSH client, you should definitely check out our Token2Shell/MD! It's now even on sale for $.99 (USD) until 11/5/2015!
