encryption algorithm class to generate a decryptor object and implement the ICrytoTransform interface. He needs the key and IV value. 5. Use the decryption object to initialize a ciphertext data stream (CryptoStream object ). This data stream also needs to know what data you want to decrypt and a source data stream from which encrypted data is read. 6. Use the ciphertext data stream to read the decrypted data (you can use StreamReader. ReadToEnd to o

Enhancement of message ing by wtl Restoring wparam and lparam data transmitted by Win32 APIs through messages is troublesome and error-prone. Unfortunately, ATL does not provide us with more help, we still need to restore the data from the message, except for the wm_command and wm_notify messages. However, the emergence of wtl has saved all of this! The extended message ing macro of wtl is defined in atlcrack. h

During the tracing process, even if some program code is found, it is difficult for the decrypted to find the association between the other two codes and all three parts. The program is difficult to crack. Use the response string returned by the encryption lock as a parameter in the program. For example, if an algorithm unit returns the "response strin

Use the response string returned by the encryption lock as a parameter in the program. For example, if an algorithm unit returns the "response string" as "87611123", the "123" parameter must be used in the program. After obtaining the "response string" in the program, subtract "87611000" from the "response string" to obtain the parameter. If the

programmer certificate, you must do not only 3, you need to connect as many problems as possible in real life with computers and solve them; 5. If you want to become a hacker, try to create things and solve all possible problems. I hope that you can position yourself on the second or higher level. This is not only an attitude issue, but also a realm of life. Set your own goals to a high point, far away, in order to show the value of a person. Here, by the way, we will give explanations for
