Use librandom (not implemented yet).

Disable automatic seeding. This is the default on some operating systems where

+Setting the FIPS HMAC key
+-------------------------
+
+ --fips-key=value
+
+As part of its self-test validation, the FIPS module must verify itself
+by performing a SHA-256 HMAC computation on itself. The default key is
+the SHA256 value of "the holy handgrenade of antioch" and is sufficient
+for meeting the FIPS requirements.
+
+To change the key to a different value, use this flag. The value should
+be a hex string no more than 64 characters.

"descrip.mms" on OpenVMS). This requires that there is a
