DiceCheck-x ™ is an easy Linux application to test that DiceChecker-x ™ FREE product that you are using is working correctly.
There are two kinds of inputs (that you can select with just 2 clicks), input file to check and the random number tests that you want to verify. |
 |
DiceChecker-x™ library allows random number tests to work with PhysicalCryptoRandomStream class, the class that keeps allocated virtual memory in RAM, preventing that memory from being paged to the swap area. The process using DiceChecker-x with PhysicalCryptoRandomStream class must be privileged (CAP_IPC_LOCK) in order to lock memory, and since Linux 2.6.9, no limits are placed on the amount of memory that a privileged process can lock and the RLIMIT_MEMLOCK soft resource defines the limit on how much memory an unprivileged process may lock.
The available random number tests to be checked are:
|
· Frequency |
|
· Block Frequency |
|
· Cumulative Sum Forward |
|
· Cumulative Sum Reverse |
|
· Runs |
|
· Longest Run Of Ones |
|
· Rank |
|
· Universal |
|
· Approximate Entropy |
|
· Serial |
|
· Discrete Fourier Transform |
The random number test checks are performed with the following files, one of them must be selected in order to make the check:
|
· Test file E |
|
· Test file PI |
|
· Test file SQRT2 |
|
· Test file SQRT3 |
|
· Test file SHA1 |
And that's all, once the tests are executed you can verify that the .so (shared library) is working correctly.
