1. calculation principle of large numbersThe RSA algorithm relies on the calculation of large numbers. Currently, mainstream RSA Algorithms are based on the calculation of large numbers ranging from 512 to 1024 bits. Therefore, we need to first

Sometimes we may define a BOOL B; B = YES; NSLog (@ "BOOL -- B --> % @", B); then the running program will crash, this is because % @ prints an object and BOOL is a data type. Use % @ to ensure that the corresponding parameter must be an object and

C language, designed and implemented in the 1970 s, is doomed to a language with a strong engineer culture and lacks some academic atmosphere. Its many details are designed with a strong trace of practical use. C language is born from a UNIX
