 2. wolfSSL Inc also wanted an option available should one wish to call one of the ESV validated entropy sources so a callback option made sense.

 A: Absolutely! wolfCrypt FIPS modules v2.x (cert #3389, 140-2 module) has 100% API compatibility minus the 3DES services with wolfCrypt FIPS module v5.2.1 (cert #4718, 140-3 module). In addition to the 140-2 APIs, there are new services (TLS KDFs, AES-OFB, etc) and newer extended APIs. For a full list of new services and new API definitions supported by the 140-3 module please refer to the FIPS 140-3 User Guide [UG] which includes an exhaustive list of every FIPS service and correlated API + description(s). If you need a copy of the [UG] please let the wolfSSL team know by emailing support@wolfssl.com requesting a copy of the FIPS [UG].

 If a user-supplied seed routine is to be used in conjunction with the TLS layer, wc_SetSeed_Cb(user_seed_function) must be called after the initial wolfSSL_Init(), and before the application calls wolfSSL_CTX_new().

 To avoid potential implementation bugs users could alternatively use the setting #define CUSTOM_RAND_GENERATE' and register their own custom RNG seed gen callback.
