Cloudera software, specifically in its distribution of Hadoop*, Navigator Encrypt*, provides transparent data encryption and key management to secure sensitive data at rest.
The OpenSSL* ENGINE API includes an engine specifically for Intel® Data Protection Technology with Secure Key. When this engine is enabled, the RAND_bytes() function will exclusively use the RDRAND instruction for generating random numbers and will not need to rely on the OS's entropy pool for reseeding. End applications can simply call RAND_bytes(), do not have to invoke RAND_seed() or RAND_add(), and the OpenSSL library will not call RAND_poll() internally.
