I have 2 questions about Message Secret Number generation of ECDSA in wolfSSL.

Q1. According to Appendix B.5 in NIST FIPS.186.4, what method to be used for Message Secret Number generation in wolfSSL?
      It is generated by (1) using Extra Random Bits or (2) Testing Candidates or others?


Q2. How Message Secret Number will be handled in wolfSSL when the value of Secret Number so calculated is zero or greater than n -1? ('n' is a prime number in Secret Number generation algorithm)


I want to evaluate ECDSA algorithm with my customer's requirements.  smile
