Product Overview
----------------

SecureCRT protects your passwords, user accounts, and data, combining
rock-solid terminal emulation with the strong encryption, broad
authentication options, and data integrity of the Secure Shell (SSH)
protocol.

SecureCRT provides versatile solutions for a wide range of business,
network management, information security, and development tasks, from
accessing host-based applications and administering servers to
securely accessing behind-the-firewall network resources like e-mail,
files, and printers.

SecureCRT supports SSH1, SSH2, Telnet, Telnet/SSL, RLogin, Serial,
and TAPI protocols and authentication via password, public key, X.509
certificate, and Kerberos v5 via GSSAPI.  Ciphers include AES,
Twofish, Blowfish, 3DES, and RC4.

Choose from a wide range of emulations including VT100, VT102, VT220,
ANSI, SCO ANSI, Wyse 50/60, Xterm, and Linux console -– all with ANSI
color.  Multibyte character sets are supported for Japanese, Korean,
and Chinese, as is support for scalable line-drawing fonts.

SecureCRT features a multi-session tabbed interface with extensive
session management and customization features.  Customization options
include toolbars, menus, keymaps, and login scripts, as well as fonts,
cursors, and color schemes. 

Named sessions and firewalls let you create individual configurations
that can be used on a session-specific basis.  Other features include
the Activator tray utility to minimize desktop clutter, auto logon,
printing, Emacs mode, and SOCKS firewall support.

Powerful scripting capabilities, including ActiveX scripting support
for VBScript and other scripting languages, save you valuable time by
automating routine configuration tasks.  Secure file transfers can be
performed using Zmodem or Xmodem from an SSH1 or SSH2 session. 

SecureCRT and the SecureFX(R) file transfer client can be integrated,
letting you share global and session options and the host key database
so configuring a server connection only needs to be done once.

SecureCRT includes a 30-day try-before-you-buy evaluation license for
the fully functional application and access to VanDyke Software(R)
technical support.

1. New For SecureCRT 5.5
------------------------

The major new features for SecureCRT 5.5 are:

  New productivity enhancements.

    Script recorder: Quickly create a script to automate routines
    using the new script recorder, which records keystrokes including
    function keys, and then generates a VB script.

    Improved auto session: With "Use auto session" enabled, you can
    now select a single session, multiple sessions, or folders of
    sessions to automatically connect on startup.

    Cache passwords: SSH2 session passwords can be cached like
    passphrases.  SecureCRT and SecureFX can share passwords while
    either application or the Activator utility is running.

  Improved ANSI color with color schemes.
    When using ANSI color, you can now select a color scheme to
    replace the standard white foreground and black background.

  Expanded logging options with custom log data.
    Custom log data gives you the ability to specify strings to be
    logged upon connect, disconnect, and on each line.  Parameter
    substitutions for session and date information are supported.

  Support for OpenSSH format keys.
    You can now generate keys in OpenSSH format or convert existing
    VanDyke Software format private keys to OpenSSH format, allowing
    you to use the same keys with other Secure Shell clients.

  Support for zlib@openssh.com compression.
    When zlib@openssh.com compression is specified, compression starts
    after authentication, preventing unencrypted passwords from being
    cached by the zlib library.

  Additional tab support.
    Display the list of tabs on the menu using the MENU_TAB_LIST1
    custom menu item. A new script function, GetScriptTab, returns the
    tab from which the script was started.

  Windows Vista support.
    SecureCRT has been tested under Windows Vista, so when you are
    ready to move to Vista, SecureCRT will be compatible.

By default, SecureCRT 5.5 stores all settings and sessions in:

  "C:\Documents and Settings\<Username>\Application Data
    \VanDyke\Config"

If a version of SecureCRT older than 5.0 was installed, your settings
and sessions will need to be migrated, which will move them to a new
location.  If migration is necessary, you will be prompted for the
new location the first time you run SecureCRT 5.5.

SecureCRT supports Windows Vista 2003, XP, and 2000.
