, so we make it as easy as possible for more innovative users to customize Kali Linux (or even custom kernels) to the way they like it. Armel and ARMHF support: since arm-based devices have become increasingly popular and inexpensive, we know we should do our best to do Kali arm support. So there is now a system of Armel and ARMHF architectures. Kali Linux has the full mainline release of the arm source, So the arm version of the tool will be updated with other versions at the same time. Kali

1. The class file is a set of binary streams with 8-bit bytes as the basic unit. Each data item is strictly arranged in the class file in order, without any Separator in the middle, this makes almost all the content stored in the entire class file necessary data for running the program, and there is no gap. When a data item needs to occupy more than 8 bytes of space, it is divided into several 8 bytes for storage according to the method of the top position. 2. According to Java Virtual Machine r

The class file format uses a structure similar to the C language structure to store data, which has only two data types: unsigned number and table.The unsigned number belongs to the basic data type, and the different lengths of the data items are represented by U1, U2, U4, U8, respectively, representing a data item that occupies one byte, two bytes, 4 bytes, and 8 bytes in the class file.A table is a composite data type that consists of multiple unsig

, these byte streams are strictly in accordance with the specified order, and there is no gap between the bytes, for more than 8 bytes of data, will be stored in the order of Big-endian, that is, high byte stored in the lower address, And the low byte storage to high address above, in fact this is also the class file to cross the platform of the key, because the PowerPC architecture processing using Big-endian storage order, while the x86 series of processors in the Little-endian storage sequenc

represented by a single byte is represented by multiple contiguous bytes. According to the Java Virtual machine specification, the Class file stores data in a pseudo-structure similar to the C language structure, with only two data types: unsigned number and table. The Java Virtual machine specification defines U1 , U2 , U4 , and U8 to represent 1 bytes respectively , 2 bytes, 4 bytes, and 8 bytes of unsigned numbers, the unsign
