ok,

so we will make a parallele dev on dtls and  ssl ;)

I have no time this week I'll start to correct preferences and others
stuff in dtls dissector from monday.
I'll inform you ....

regards,

Samuel

PS: what is the things that are missing in ssl dissector (I have
stopped dev because I tought that all was done....) thanks for your
answer....

ah, a misunderstanding.

ok.    so the dtls stuff does not require linking with openssl then
there wont be any problem at all.

thanks for clarifying.



please also see   wiki.wireshark.org/SSL
i just checked in a change to the preference syntax that is not
backward compatible for ssl decryption.

i think it makes it better.   please mimic these changes in dtls
dissector   (i have little interest in dtls personally now   but great
interest in ssl decryption)


i will do more changes and refactoring to ssl decryption over time.
