   4 Subject: [PATCH] wolfSSL: Fix crypto_bignum_sub()
   5
   6 The initial crypto wrapper implementation for wolfSSL seems to have
   7 included a copy-paste error in crypto_bignum_sub() implementation that
   8 was identical to crypto_bignum_add() while mp_sub() should have been
   9 used instead of mp_add().
