Detailed Description

Class for generating an MD5 hash

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_md5_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 is received at input PIN_I_DO_HASH, a hash code is formed for the data block (string) at input PIN_I_DATA. Then the hash code is output as hexadecimal number at output PIN_O_HEXCODE
