2.3.7.6 Binary Document XOR Data Transformation Method 2

  • Article

Data transformed by Binary Document XOR data transformation method 2 takes the result of an XOR operation on each byte of input in sequence and the 16-byte XOR obfuscation array that is initialized as specified in section 2.3.7.2, except when the byte of input is 0x00 or the binary XOR of the input and the obfuscation array element is 0x00, in which case the byte of input is not modified. When the end of the XOR obfuscation array is reached, start again at the beginning.
