Re: Re: Ask for mentor - Improve Bcrypt

Hey Kaiyi Zhang,

Welcome to wine dev! If you decide to move forward with this(DH and DSS), I
wish to share with you all that I have finished up to now. Using a few
things from RSAENH I have all the related algorithms functioning. Also
using LibTomCrypt I have partially implemented DSA but you would have to
choose on the PRNG that DSA will use. My plan was to use RC4 but have not
gotten to test that. I have yet to touch anything with DH_EPHEM (Ephemeral)
or DH_SF (Store and Forward).  If you have any questions shoot them to Juan
or me (Juan is the better choice). Best of luck!

Ask for mentor - Improve Bcrypt

[Kaiyi Zhang]

Hi  Marek:
According to Lang's suggestion, I think DH and DSS is a better choice.
Thanks for your generous. DH and DSS is strange to me. I need to to learn
more about this. I accept it 's difficult for me to absorb your proposal .
it's better for me to get this step by step. As i said in my gsoc
proposal I'm interested in this. joining the wine  project is the best for
me.

thank you.
