Numeric constant conversion

Confuse and encrypt constant numbers in the hap code, making it impossible for crackers to use them to quickly locate the core code of the program

Boolean constant conversion

Convert boolean constants in the hap code into complex logical expressions, making it difficult for crackers to directly identify boolean constants from the code, effectively increasing the difficulty of code reverse engineering

String slicing

Cut strings in the hap code into multiple sub-strings, and recombine or disperse them to different positions in the code, effectively protecting the core code

Control flow flattening

Flatten the control flow corresponding to functions in the hap code 'horizontally,' making it more difficult for crackers to analyze using common decompilation tools, effectively protecting the original logic of the core algorithm

String encryption

Perform syntactic and logical analysis on the hap code, accurately parse the positions of strings in the code, and then use advanced encryption algorithms to obfuscate and encrypt the strings.The subsequent string is difficult to reverse engineer, thus preventing crackers from using it to quickly locate the position of the program's core code

Variable merging and conversion

Merge and transform variables in the hap code to reduce the number of variables, disrupt the original structure of variables, making it difficult for crackers to understand the relationships between variables in the code, and increasing the complexity of reverse engineering

If - statement conversion

Analyze the hap code to locate all if statements. Convert simple if statements into complex nested structures or logical expressions, making the logical judgment of the code obscure, thereby preventing crackers from quickly mastering the core logic of the program by analyzing if statements

Expression key conversion

After identifying and analyzing expression keys in the hap code, convert them into a more complex form. For example, use function calls, mathematical operations, and other methods to transform expression keys, making it difficult for crackers to recognize the original expression keys and increasing the difficulty of code reverse engineering

Flower Instruction Injection

After in-depth analysis of the HAP code, inject some seemingly meaningful but actually harmless code at appropriate positions, which are known as flower instructions. These flower instructions interfere with the analyst's thought process, thereby enhancing the security of the code

Member expression conversion

Analyze and locate member expressions within the HAP code, transforming them into complex forms. This involves confusing the code by altering the way members are accessed and adding extra intermediate variables
