+       help
+         This option enables support of hashing using SHA1 algorithm.
+         The hash is calculated in software.
+         The SHA1 algorithm produces a 160-bit (20-byte) hash value

+       help
+         This option enables hardware-acceleration for
+         SHA1/SHA256 progressive hashing.
+         Data can be streamed in a block at a time and the hashing
+         is performed in hardware.
