clsha1 [OPTION] [FILE]

No FILE or "-" reads from standard input.

-base64 | -b64

   prints the hash value base64 encoded. Without this option the hash value
   is printed hexadecimal

--help

   prints a help text

--version

   prints the version of clsha1

clsha1 uses the cryptlib shared object library and its python3 bindings.
