# Functions

No description provided by the author
No description provided by the author
Peek takes a net.Conn and reads a TLS client hello message if possible.
PrefixIsTLS will return if an incoming connection is, in fact, likely to be a TLS connection.
Read reads a full TLS client hello.
ReadHandshake reads an incoming TLS handshake message.
ReadRecord reads a single TLS record.

# Constants

PrefixLength is the number of bytes required to determine if the connection is a TLS connection.

# Structs

ClientHelloMsg is a Go struct version of the TLS client hello message.
PrefixConn wraps a net.Conn but attaches a prefixed amount of data to the incoming side.
RecordingReader wraps another io.Reader but keeps track of what it has read so far.
