Whatever you have mailed is correct, but I believe the TLS 1.0 RFC explains
all these in details. Try reading 2246 from ietf.org.

Hi All
I have a general question about RSA Key Block.
The output of PRF with the master_secret to give us many keys. It
includes: client_write_MAC_secret, server_wriet_MAC_secret,
client_write_key, server_write_key, client_write_IV, server_write_IV.
Could you Please verify what I think about how four of these keys being
use correcly:
1) SSL record format: Length + Data + MAC ( in general) : client----> server
client_write_MAC_secret is used to encrypted the MAC portion message
from client---->server
client_write_key is used to encrypted the Data portion message from
client----> server
2) SSL record format: Length + Data + MAC ( in general) : server----> client
servert_write_MAC_secret is used to encrypted the MAC portion message
from server----> client
client_write_key is used to encrypted the Data portion message from
server----> client
3) Data from Sever to Client is encrypted with different key from Client
to Server ???.
I just want to understand what going on underneath openssl.
Thank You
TD
