 ## Why does this library exists?
 
-The censorship circumvention system [Snowflake](https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snowflake) has previously been blocked by fingerprinting the dtls handshake. This library is a module that extends the `pion/dtls` library by hooking and manipulating messages to make them indistinguishable from other dtls implementations used for webrtc traffic.
