Systems for performing methods which include receiving by a VPN server, from a VPN client operating on a computing device, over a VPN connection a first message including a first IP address. The VPN server determines a hostname based on the first IP address, resolves the hostname to a second IP address, and transmits the first message to a network device at the second IP address.

A method of filtering a URL against a blacklist includes receiving at least a portion of a Uniform Resource Locator (URL), and determining which of a plurality of XOR filters is applicable to the received at least a portion of a URL, where each of the plurality of XOR filters represents a different portion of a URL blacklist. At least a portion of a URL is forwarded to the applicable one of the plurality of XOR filters, and the at least a portion of the URL is processed in the applicable one of the plurality of XOR filters to produce an output indicating whether the URL is likely on the blacklist.

Blocked XOR filter for blacklist filtering

A system, computer-readable storage medium, and method for secure network communication. A first device employs a first secret to establish a stream between the first and a second device. A third key, first ciphertext based on a first key, and hash of the first key are received from the second device by the first. A second key is applied to recover a second secret from the first ciphertext. The third key is encrypted to generate a second ciphertext including a third secret. Fourth and fifth keys are derived based on the first, second, and third secrets. A message authentication code is generated based on the fourth and third keys, first ciphertext, hash of the first key, and second ciphertext. The second ciphertext and message authentication code are transmitted by the first to the second device, and the fifth key is employed by the first device to modify the stream.
