I have a socket application that uses obfuscation right now for security basically a shared 32 bit mask-key that when or'd with a random,server transmitted hexstring, the client
can determine the sum of the derived key and return the a
summed hextodec by pair decimal value so the transaction can be verified. A window determines the frequency of the auth checks.
Like:
1151d33b4d5d8be79bc845f34c45b984=server random key 00110010100111001110100000111101=private mask
5134d8b9bc445b94=derived private key
1029=client auth sum
window=3
This is all plain text and seems easy to defeat.
Has anyone used the tls package for tcl or can recommend
a good set of example scripts for this extension?
Thanks
MMD
