MD5 is an insecure cryptogrpahic hashing algorithm and is therefore
blocked in FIPS mode. NumPy uses MD5 has digest algorithm without any
security requirements. Use `usedforsecurity=False` flag to tell OpenSSL
that the use of MD5 is okay in FIPS enforcing mode. I implemented the
flag in Python 3.9 for exactly this purpose
