This class installs the urandom fix for Java.
On Linux low entropy can cause certain operations to be very slow. Encryption operations need entropy to ensure randomness. Entropy is generated by the OS when you use the keyboard, the mouse or the disk.
If an encryption operation is missing entropy it will wait until enough is generated. Which can slow down your system.
To fix this, there are three options:
- use rngd service (this class)
- set java.security in JDK ( jre/lib/security )
- set -Djava.security.egd=file:/dev/./urandom param
To use the rng service, just add:
to your manifest.
