To encrypt a string, perform the following steps:
1. Convert the source string into a byte array
2. Initialize an encryption algorithm class
3. Use this encryption algorithm class to generate an encryption entity (encryptor object) and implement the IcryptoTransform interface. He needs the key and IV value.
4. Use the encryption object to initialize a ciphertext data stream (CryptoStream object ). This data stream also needs to know which data you want to encrypt and the target data stream used
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. (This name comes from the "message decryptor", which is similar to Windows X. h macros use the same term.) First, change begin_msg_map to begin_msg_map_ex, and generate the code for "decrypting" The message with _ ex.

// Read out the result from the crypto stream

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 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 decryptor modifies the code to skip the query and verifica

Aircrack is a suite of software utilities that acts as a sniffer, packet crafter and packet decoder. A targeted wireless network is subjected to packet traffic to capture vital details about the underlying encryption. A decryptor is then used to brute-force the captured file, an

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!

If the decryptor modifies the code to skip the query and verification encryption lock section, the parameter will be an error value, which will cause program running disorder. When the program verifies the encryption algorithm, the program will choose to exit if the verification data is

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.
