Hello, ? To grasp how FIPS methods are called, and following one method as an example, HMAC_Update() in hmac.c, we can see that if FIPS mode is active then FIPS_hmac_update() will be called.? This is fine although searching the sources for the physical definiton of FIPS_hmac_update() does not yield any results.? How does the symbolic links function, what ends up being executed in this case and through which path ? Thanks, regards.
