Myths about /dev/urandom (2014) | Hacker News

Hacker News revisited a 2014 article challenging common myths about Linux /dev/urandom and PRNG security.

Commenters debated whether weak entropy and PRNG prediction have caused real-world exploits, not just theoretical concerns.

The thread pointed to concrete failures such as the Debian SSH key bug and other entropy-related vulnerabilities.

The discussion underscored how OS randomness affects key generation, encryption, and overall resistance to attack.
