Anonymity Considerations

When designing and implementing a Pluggable Transport, care should be taken to preserve the privacy of clients and to avoid leaking personally identifying information.

Examples of client related considerations are:

• Not logging client IP addresses to disk.

• Not leaking DNS addresses except when necessary.

     - Ensuring that "TOR_PT_PROXY"'s "fail closed" behavior is
       implemented correctly.

Additionally, certain obfuscation mechanisms rely on information such as the server IP address/port being confidential, so clients also need to take care to preserve server side information confidential when applicable.
