tinycrypt: Add test case for the CTR PRNG algorithm
This commit adds the test case for the CTR PRNG algorithm. Origin: https://github.com/01org/tinycrypt/tree/v0.2.0 The code was refactored to eliminate malloc and free function calls and checkpatch errors. However, many warnings are still present. Refactoring history is available at: Repo: https://gitlab.com/santes/tinycrypt/commits/refactoring Commit: 5d0482c26c4ad69e7854dde58d15bb57a3e5f18f Jira: ZEP-614 Jira: ZEP-860 Change-Id: I0620868d092941931762718c81fe13fc01f251b2 Signed-off-by: Flavio Santes <flavio.santes@intel.com>

Title: test_ctr_prng
|
||||
|
||||
Description:
|
||||
|
||||
This test verifies that the TinyCrypt CTR PRNG APIs operate as expected.
|
||||
|
||||
--------------------------------------------------------------------------------
|
||||
Building and Running Project:
|
||||
|
||||
This microkernel project outputs to the console. It can be built and executed
|
||||
on QEMU as follows:
|
||||
|
||||
make qemu
|
||||
|
||||
--------------------------------------------------------------------------------
|
||||
|
||||
Troubleshooting:
|
||||
|
||||
Problems caused by out-dated project information can be addressed by
|
||||
issuing one of the following commands then rebuilding the project:
|
||||
|
||||
make clean # discard results of previous builds
|
||||
# but keep existing configuration info
|
||||
or
|
||||
make pristine # discard results of previous builds
|
||||
# and restore pre-defined configuration info
|
||||
|
||||
--------------------------------------------------------------------------------
|
||||
|
||||

|
||||
|
||||
