Hello,
I found this library : http://www.yassl.com/
The main implementation claims (partial) OpenSSL compatibility. There is a C implementation in development - cYaSSL - targetted for small footprint.
There is already matrixssl in OpenWrt repositories but the OpenSSL compatibility is a good point. However I don't know exactly how far goes the compatibility with cYaSSL for now.
Does anyone knows it or tested it ?
ffrrrr
