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.
