Entropy Daemon

OpenSSL requires a source of random data for providing strong cryptographic operations. Random number generation is a capability that is usually provided by the operating system or by a system-wide daemon process. The HP Integrity NonStop Server operating system does not provide this capability within the operating system.

When you are using the SSL and TLS support supplied with IBM® MQ client for HP Integrity NonStop Server, a process that is called an entropy daemon is needed to provide the source of random data. When you start a client channel that requires SSL or TLS, OpenSSL expects an entropy daemon to be running and providing its services on a socket in the OSS file system at /etc/egd-pool.
