162 = 256; 3 x 256 = 768; 840 - 768 = 72; 4 x 16 = 64, 72 - 64 = 8Hexadecimal equivalent of 840 = 348

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

5x = 125 3x = 27 1/3 x 4x = 64/3

64^3 is equivalent to 262,144 or 64*64*64

8 * 8 = 64, 4 * 16= 64, 2 * 32 = 64, 64 * 1 = 64

Each of the 64 hexadecimal characters encodes 4 bits of binary data, so the entire 64 characters is equivalent to 256 binary bits - which is the actual binary key length used by the WiFi WPA pre-shared key (PSK).

The 64 bit WEP key uses a 40 bit (10 Hex character) Encryption and a128 bit WEP key uses a 104 bit (26 Hex Character) Encryption.So the 128 bit WEP key is a higher level of encryption compared to 64 bit WEP.

Hex(41) = 4*161+1 = 64+1 = 65

Most keyboards have a set of mapped keys. This will vary on the file that is loaded, many have a specific key for this character. However holding down the 'Alt' key and typing 64 will produce it. @

Hexadecimal is used whenever we want to notate a binary value because each hex digit maps directly with each 4 bit nybble (half a byte). A 64-bit binary value can therefore be reduced to a more concise 16-digit hex value.
