How pcAnywhere works with encryption
Symantec pcAnywhere uses a combination of symmetric and public-key encryption.
By combining both techniques, pcAnywhere takes advantage of the strengths of
each method: speed and security.
Symantec pcAnywhere provides the following options for protecting the data
stream between a host and remote computer during a remote session:
■
pcAnywhere encoding
■
Symmetric encryption
■
Public-key encryption
If the host computer and remote computer are running pcAnywhere 11.5 or later
and the encryption levels do not match, pcAnywhere automatically raises the
encryption level on the computer that is using the lower level to match the
encryption level on the computer that is using the higher level. If you are using
symmetric encryption, pcAnywhere also raises the algorithm levels if the one of
the computers is using a lower level.
For example, if the host encryption level is configured for pcAnywhere encoding
and the remote encryption level is configured for symmetric encryption,
pcAnywhere automatically raises the encryption level on the host to symmetric.
If either the host computer or the remote computer is running pcAnywhere 11.0.x
or earlier and the encryption levels or algorithms do not match, Symantec
pcAnywhere attempts to lower the encryption level on the computer that is using
the higher level to match the encryption level on the computer that is using the
lower level. You can configure pcAnywhere to deny the connection instead.
See “Denying connections from computers that use lower encryption” on page 216.
Configuring pcAnywhere to use pcAnywhere encoding
Symantec pcAnywhere encoding applies a simple transformation to data so that
the data stream cannot be easily interpreted by a third party. This encryption
level is compatible with earlier versions of pcAnywhere that do not support
stronger encryption techniques.
To configure pcAnywhere to use pcAnywhere encoding

In the Symantec pcAnywhere window, in Advanced View, do one of the
following:
■
To set up pcAnywhere encoding on the host computer, on the left
navigation bar, click Hosts.
