During SSL decryption, several factors can impact resource consumption. Firstly, the key exchange algorithm affects the processing power required because different algorithms have varying complexities. Secondly, the transaction size influences the amount of data being decrypted, which in turn affects resource usage. Lastly, the TLS protocol version can determine resource consumption based on the specifications and security features of the protocol version in use. These three factors collectively play a significant role in determining the resource consumption during SSL decryption.
