Detailed Description

Class to generate a SHA-1 hash value

Part of the packet for encryption

class Crypto_HASH(hsl20_4.BaseModule):

    def __init__(self, homeserver_context):
        ....
        

    def on_input_value(self, index, value):
        if index == self.PIN_I_DO_HASH:
            hash = self.FRAMEWORK.create_sha1_hash()
            hash.update(self._get_input_value(self.PIN_I_DATA))
            self._set_output_value(self.PIN_O_HEXCODE, hash.hex_digest())

If a telegram arrives at input 2 (PIN_I_DO_HASH), a hash code is formed for the data block (string) at input 1 (PIN_I_DATA). Then the hash code is output as hexadecimal number on output 1 (PIN_O_HEXCODE)
