Whats the difference between 40- bit and 128-bit encryption?
The 40-bit encryption and the 128-bit encryption differ in their complexity and the key length. 40-bit encryption can use one of the 240 possible different combinations (1 followed by 12 zeroes) and 128-bit encryption uses on of the 2128 possible different combinations (3.4 followed by 38 zeroes). 128-bit encryption is exponentially more powerful than 40-bit encryption. According to Netscape, 128-bit encryption is 309,485,009,821,345,068,724,781,056 times more powerful than 40-bit encryption.
