SecureCRT is a commercial terminal emulator supporting xterm and VT200 terminals with Telnet, Rlogin and SSH protocols.

Quote from the SecureCRT web site:

"SecureCRT combines rock-solid terminal emulation with the strong encryption, broad range of authentication options, and data integrity of the Secure Shell protocol."

VanDyke Software provides a Voluntary Product Accessibility Template (VPAT) detailing the compliance of SecureCRT with section 508 of the Rehabilitation Act to assist people with disabilities.

Communication

SecureCRT provides 5 basic communication protocols.

  • Telnet - standard Telnet protocol used for terminal communication with most systems. All data on the network is in plain-text which could be viewed by anyone with a network sniffer between the PC and the target server.
  • Telnet/SSL - standard Telnet protocol with SSL encryption
  • SSH - an encrypted implementation of communication similar to Telnet. All communication cannot be viewed while on the network. SecureCRT includes support for:
    • Authentication methods
      • Keyboard-interactive - username and password verified by SYSUAF
      • Public key
      • Stored password
      • GSSAPI - Kerberos GSSAPI or Microsoft Kerberos
    • Tunneling including X11 forwarding
  • RLogin
  • Serial - COM1 - COM50 with software or hardware flow control

File transfers may be done using one of 5 different protocols.

  • SFTP - Secure FTP
  • Plain text
  • X-Modem
  • Y-Modem
  • Z-Modem

Keyboard Mapping

Due to the diferences between the DEC VT series keyboards and the standard, and some not-so-standard, PC keyboards, terminal emulators must choose how to map many of the function and editing keys. The default keyboard configuration for SecureCRT includes mapping of the editing keys based on key function.

The 6 editing keys on the VT series keyboards are:

Find Insert Remove
Select Previous Next

These keys are mapped to standard PC keyboard for these keys is:

Insert Home Page Up
Delete End Page Down

Key mapping based on key function maps the PC keys to the DEC VT keys as:

  • Insert -> Insert
  • Home -> Find
  • Page Up -> Previous
  • Delete -> Remove
  • End -> Select
  • Page Down -> Next

Function keys F1-F4 are mapped to the DEC VT keys PF1-PF4. Function keys F6-F12 are mapped to the DEC VT function keys F6-F12. Shift F1 - shift F10 on the PC keyboard are mapped to the DEC VT function keys F11-F20.

By default, the backspace key is mapped to the backspace key. For compatibility with DEC VT terminals, this should be changed in the keyboard setup. To enable the use of the editing keys listed above, the terminal emulation should be set to VT220 or xterm.

Individual key mapping may be changed in the "Mapped Keys" option of the configuration.
