In particular, is the Karatsuba multiplication (`bn_mul_recursive`) and/or Comba multiplication (`bn_mul_comba4`, `bn_sqr_comba8`, `bn_sqr_comba4`, etc.) actually useful, or is it just needless complexity?\r\n\r\nWe already made RSA signing and RSA verification independent from it, AFAICT. (That needs to be verified.) RSA key generation (#219) might need these optimizations?"}}
