Secure Shell Overview

You can configure Secure Shell connections when you need secure, encrypted communications between a trusted host and your PC over an insecure network. Secure Shell connections ensure that both the client user and the host computer are authenticated; and that all data is encrypted. Passwords are never sent over the network in a clear text format as they are when you use Telnet, FTP, or rlogin.

Encryption Standards

Encryption protects the confidentiality of data in transit. This protection is accomplished by encrypting the data before it is sent using a secret key and cipher. The received data must be decrypted using the same key and cipher. The cipher used for a given session is the cipher highest in the client's order of preference that is also supported by the server. You can use the Encryption tab of the Reflection Secure Shell Settings dialog box to specify which ciphers the Secure Shell connection should use.

Attachmate Reflection 2008 supports the following data encryption standards:

  • DES (56-bit)
  • Arcfour (40- or 128-bit)
  • TripleDES (168-bit)
  • Cast (128-bit)
  • Blowfish (128-bit)
  • AES (also known as Rijndael) (128-, 192-,or 256-bit)
