Python Implementation Method for RC4 file encryption, This article describes how to implement RC4 file encryption in python. Share it with you for your reference. The specific analysis is as follows: Based on the RC4 stream encryption algorithm, the extended 16*16 S box and

When you use vi or vim to edit folder encryption, you should use wq or: x to exit when saving the disk, but sometimes you may accidentally Press: X. In this case, the system will prompt: enterencryptionkey: If you have not carefully read the prompt, for example, continue to input: x, Enterencryption... When you use vi or vim to edit folder encryption, you should use wq or: x to exit when saving the disk, b

File encryption and decryption Experiment [Experiment content] Use des, AES, and RC2 algorithms to encrypt and decrypt texts, images, audios, videos, and other files. File encryption and decryption Experiment [Experiment principle] Some of the computer's unsuitable private or confidential files are easily stolen and

ObjectiveIn the daily development, you may encounter to be sensitive to the system of code to protect, then the following summarizes the way to protect the source of the simplest way, that is, file encryptionFirst of all, the general idea of encryption and decryption is: encryption is nothing more than the class file i

resource manager, but can be opened in the "run" column, provided that the real path of the folder is known. For example, you can open this folder by typing "E: \ damojinghong \" in the "run" column and pressing the Enter key.Finally, let's talk about how to delete these folders. In cmd, enter rd E: \ damojinghong \ to delete the file.As you can see, many friends may find that creating such a folder can not only be deleted by mistake, but also store some important data to achieve the effect of

Python code encryption source code protection-pyc file 'bytecode'The practical application of Python code encryption has become increasingly popular, it has become indispensable in real life. This article mainly introduces the Python code encryption operations through the actual application method of the pyc

General encryption PHP file restoration method previous article practice restoring PHP encrypted files said I found the PHP encrypted file method is insufficient, so this article was available. Background Analysis As we all know, PHP is a scripting language, which is mainly used to explain and run rather than compile and run. Therefore, compared with compiled la

Adding salt is a way to increase the file encryption strength. We know that encryptionAlgorithmThe longer the user password, the stronger the encryption strength (when the user password is fully utilized). In fact, the so-called "salt" is to encryptProgramThe password is set. The program randomly generates several random numbers during the

answer after 10 retries. 2. dictionary attack. Compared with the mentally retarded child, the dictionary attack is probably the IQ of a three-year-old. It uses a dictionary file and tries every password in the file one by one. Nowadays, many people share their dictionary files on the Internet, which makes dictionary attacks much more efficient than brute-force cracking. Especially when the target
