Hello, Following on the 'SP800-90 DRBG in OpenSSL FIPS 140 for SP800-90A?' topic, the OpenSSL source code does not seem to mention SP 800-90A.? Only SP 800-90.? So the certifications were made for SP 800-90, is that right ? Also, does it depend on the application to choose which DRBG and moreover, for regular FIPS uses, does it matter which DRBG is used since they are all approved ? One more question: is there a way for us to actually know/test which one id used by an application ?? I currently am using a FIPS_post_set_callback() placed in FIPS_mode_set() - can this be useful to identify which DRBG is used ?? Maybe FIPS_drbg_set_callbacks() could be more useful ? Regards.
