How strong is 40-bit encryption?
40-bit encryption is not as powerful as 128-bit encryption. But this still requires a lot of dedicated effort to break. When the length of the key is increased by one bit, the amount of effort required for breaking the code doubles. However, as the power in the hands of the potential criminals increases, it is necessary to use a more complex and longer key for secure transmission of data electronically. This is being provided by 128-bit encryption.
