clsha1 - Man Page

clsha1 [OPTION] [FILE]

clsha1 calculates the SHA1 hash value of the input, either a file or standard input and prints the hash value in hexadecimal (default) or base64 encoding on standard output. The hash value is 160 bits long.

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.
