+
+Tool that computes hashes using the specified algorithm.
+Runs for 5 seconds and prints the average execution time per hash.
+Uses the EVP API by default, but this tool can also use the corresponding deprecated API's.
+Prints out the average time per hash computation.

+Usage: evp_hash [-h] [-x] [-t] [-u update-times] [-a algorithm] thread-count
+-h - print this help output
+-x - use deprecated API instead of EVP API
+-t - terse output
+-u update-times - times to update digest. 1 for one-shot (default: 1)
+-a algorithm - One of: [SHA1, SHA224, SHA256, SHA384, SHA512] (default: SHA1)
+thread-count - number of threads
