Hi,
https://tools.ietf.org/html/rfc8446
============
7.1. Key Schedule
The key derivation process makes use of the HKDF-Extract and
HKDF-Expand functions as defined for HKDF [RFC5869], as well as the
functions defined below:
HKDF-Expand-Label(Secret, Label, Context, Length) =
HKDF-Expand(Secret, HkdfLabel, Length)
Where HkdfLabel is specified as:
struct {
uint16 length = Length;
opaque label<7..255> = "tls13 " + Label;
opaque context<0..255> = Context;
} HkdfLabel;
============
In this struct, what is the value of label<0..6>?
with regards,
Saravanan
