Topic: Adding custom SRP cipher suite into wolfSSL

Hi,
Is it possible to add custom SRP-AES-128-CBC-SHA cipher suite into wolfSSL? What all steps need to be done to achieve this? I have already  done some OpenSSL applications using this cipher suite. I'm currently trying to follow instructions on this post:
https://www.wolfssl.com/forums/topic845 … urves.html.
But I'm having trouble filling out the "ssl->specs" that I have created in keys.c file. Also what are the modifications in internal.c? Is there some reference I can look at? I'm not an expert in this field. Any help is much appreciated.

Hi Arun,

Thanks for contacting wolfSSL Support. Adding support for SRP ciphers sounds great!

Here is a description of the steps for adding a custom cipher:

Re: Adding custom SRP cipher suite into wolfSSL

There doesn't seem to be a lot of information on the provided link. Is there any chance of a new wolfSSL version that supports any kind of SRP cipher suit in the near future?

Re: Adding custom SRP cipher suite into wolfSSL

Hi Arun,

I completely missed the fact that wolfSSL already has some support for SRP.
https://www.wolfssl.com/doxygen/group__SRP.html

There is even some test code you could use as an example:
https://github.com/wolfSSL/wolfssl/blob … ests/srp.c

Hope this helps!
