What is 18446744073709551616?
18446744073709551616 is the value of (2^{64}), which represents the total number of unique values that can be represented by a 64-bit unsigned integer. This number is significant in computing, particularly in data types and memory addressing. In hexadecimal, it is represented as 0x10000000000000000.
What pseudo-random block stream is generated by 64-bit OFB with a weak DES key?
With (OFB) output feed back, a random 64-bit number, known as the IV is encrypted with the weak secret key to create the one-time pad. A weak DES secret key is one which is either all 1's, 0's or alternating ones and zeros. The plain text is XOred with as many bits of the generated one-time pad. If a weak key patterns will emerge in the ciphertext. - Eric Appelboom
