 ## CRYPTO Frame {#frame-crypto}
 
 The CRYPTO frame (type=0x06) is used to transmit cryptographic handshake
-messages. It can be sent in all packet types. The CRYPTO frame offers the
-cryptographic protocol an in-order stream of bytes.  CRYPTO frames are
-functionally identical to STREAM frames, except that they do not bear a stream
-identifier; they are not flow controlled; and they do not carry markers for
-optional offset, optional length, and the end of the stream.
