String gen_sha1(String s, bool as_binary = false)

:params
s : data to be hashed
as_binary : when set to false, returns hash in hexadecimal notation (defaults to false)
return value : the resulting hash value

:content
Returns the SHA-1 hash of `s`.

When `as_binary` is `false`, the hash is returned as hexadecimal text. When it is `true`, the raw binary hash bytes are returned.


:example
print(gen_sha1("hello") != "" ? "sha1\n" : "empty\n");
