DüşükDüzey 2Otomatikbind

Açıklama

Install the haveged package to provide enhanced entropy for generating cryptographic keys. Haveged is a user space entropy daemon which is not dependent upon the standard mechanisms for harvesting randomness for the system entropy pool. Haveged uses HAVEGE (HArdware Volatile Entropy Gathering and Expansion) to maintain a pool of 1 million random bytes used to fill /dev/random. The audit requires a running haveged process (pgrep -x haveged).
