Hash Performance Test

Just a little script to check the performance difference between md5. sha1 and sha2 (256bit and 512bit)

Results

The test was executed in docker with php 7.1-fpm (offical image) on my Macbook Pro 13" (late 2012) 8GB RAM and Intel Core i5 (2,5GHz)

1.000.000 interations with a small string and the interation number as slat.
