The Web Remote uses encryption to ensure that the data that you send cannot
be read or altered by unauthorized users while in transit.
The Web Remote provides the following types of encryption:
■
pcAnywhere encoding

About pcAnywhere encoding on Web Remote
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.

About symmetric encryption on Web Remote
Symmetric encryption encrypts and decrypts data using the same set of symmetric
cryptographic keys. These keys are negotiated and exchanged using standard
protocols for anonymous key exchange. During a session, both the sender and
the recipient share these keys.
The Web Remote lets you select the symmetric encryption algorithm that best
suits your security and performance needs. Each algorithm uses a string of bits
that are known as a key to perform the calculations. You can strengthen the level
of encryption by selecting a higher key length. The larger the key length, the
greater the number of potential patterns that can be created. This makes it more
difficult to break the encryption code. Higher key lengths create stronger
encryption, but they might also result in slower application performance. The
key lengths that are available depend on the type of algorithm that you select and
your computer's operating system.

How the Web Remote works with differing encryption levels
When you connect to a host computer that is running pcAnywhere 12.0 or later,
the Web Remote automatically raises the encryption of the computer with the
lower encryption level to match the encryption of the computer with the higher
encryption level. For example, if the host encryption level is configured for
pcAnywhere encoding and the remote encryption level is configured for symmetric
encryption, pcAnywhere will automatically raise the encryption level on the host
