I'm looking for a cryptography library for my LPC8N04 Development Board. I tried to cross-compile libsodium, but for some reason I get "undefined reference" linker errors when compiling code which includes library functions. I have little experience with embedded C programming, so I'm a little lost. Does anyone here have experience with crypto libraries for the Arm Cortex M0 and could help me getting one to work on my chip? Specifically, I'm looking for an implementation of DSA/ECDSA and a SHA hash function.
