Kernel crypto API: cryptoperf performance measurement

2014-08-17 Thread Stephan Mueller
Hi, during playing around with the kernel crypto API, I implemented a performance measurement tool kit for the various kernel crypto API cipher types. The cryptoperf tool kit is provided in [1]. Comments are welcome. In general, the results are as expected, i.e. the assembler implementations
