the derivation function and when it can be omitted, see [NIST SP 800-90A
Rev. 1]. Roughly speaking it can be omitted if the random source has "full
-entropy", i.e., contains 8 bits of entropy per byte. In a FIPS context,

the derivation function can never be omitted.
Even if a nonce is required, the B<get_nonce>() and B<cleanup_nonce>()
