- 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
- (digest).

- SHA1/SHA256 progressive hashing.
- Data can be streamed in a block at a time and the hashing
- is performed in hardware.
