Hi Michael,

I would think that the issue regarding the logging is relevant for 
cryptographic use cases or use cases requiring strong random numbers only. 
Only those use cases should be fixed eventually to wait for a fully seeded 

The logged messages you present here indicate use cases where no strong 
security is required. It looks like that the logs show ASLR related use of 
random numbers. Those do not require a fully seeded ChaCha20 DRNG.

IMHO, users using the get_random_u64 or get_random_u32 are use cases that do 
not require a fully seeded DRNG thus do not need a cryptographically strong 
random number. Hence, I would think that the logging should be removed from 

Yet, logging should remain for get_random_bytes which should be denominated as 
the interface for use cases where cryptographically strong random numbers are
