This past month, we launched a new open source utility for Linux called Entropy Pool Feeder (epf). In Linux, the entropy pool is used as a source of high quality randomness for a variety of security operations. The entropy pool is accessed using the
/dev/random device. To avoid entropy pool starvation, it is important to maintain the pool with enough randomness.
epf utility can be used to properly maintain the pool, by continuously monitoring the entropy pool, and feeding it with a high quality true randomness when the entropy level is below the threshold value. The randomness can be securely downloaded from a remote service such as entropysector.com.
