The output will be base64-encoded, with trailing "==", like this:

Example
#include "mbed.h" #include "hmac_md5.h" Serial pc(USBTX, USBRX); // tx, rx void main(void) { const char * key = "MySecretKey"; const char * text = "message to be signed"; char output[26]; HMAC_MD5(key, text, output); printf("result = %s\n", output); while(true){} }
