Hi,
Question as title : I have an existing product that has an ARM Cortex M3 C PU and which I need to retrofit with assymetric crypto to send small amount s of encrypted data. The CPU I am landed with doen't have a crypto module available and cannot be changed so I need a C library that can do assymetri c crypto (key exchange etc) and still run, even if slowly) in a restricted memory space on a small ARM CPU.
Any ideas ?
Thanks,
Mike
