DigesterCheck-x ™ is an easy Linux application to test that HashDigester-x ™ FREE product that you are using is working correctly.

HashDigester-x™ library allows hash digest algorithms 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 HashDigester-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 hash algorithms to be checked are:

The hash algorithm checks are performed with the following text for each one of hash algorithm:

- for SHA 1, SHA 224 and SHA 256:

- for SHA 384 and SHA 512:

- for Ripemd 128, Ripemd 160, Ripemd 256 and , Ripemd 320:

And that's all, once the tests are executed you can verify that HashDigester-x shared library is working correctly.
