Re: adding a new custom ciphersuite to NSS (to be used by Thunderbird for TLS establishment)

***Update***

so I was doing manual patching after looking the Camellia Cipher Patch in my Thunderbird NSS direcotry on Windows platform since I want to create the the binary on windows platform and I got the following issues:

i.	pk11table.c location changed

ii.	pk11pars.h file not found [cant patch the file]

iii.	sslimpl.h had number 64 and 40 in the patch, what number should I give, following lines from orignal:
		a. #define ssl_V3_SUITES_IMPLEMENTED 64

		b. #define ssl_V3_SUITES_IMPLEMENTED 40

iv. What numbers to assign cipher in secoid.c 


ps: this patch is very old, almost a decade old, can anyone guide me or provide me a slightly new patch please thanks?
